2. Construction
(1) Steering Gear
The steering gear is of the 2-ram, 4-cylinder fork type rapson slide
electro-hydraulic, single loop system equipped with the servo
controlled hydraulic pumps.
The steering gear is so designed to move the rudder from 35 degrees on one
side to 30 degrees on the other side in 28 seconds with one(1) pump
operation with the ship running ahead at maximum service speed.
In case of single oil leakage from piping or power units, the remaining
steering gear system is to be capable of moving the rudder from 15 degrees
on one side to 15 degrees on the other side in not more than 60 seconds
with the ship at the summer draft while running at one-half the max. speed
ahead or 7 knots whichever is the greater.

(2) Tiller
Tiller to be of solid cast steel with integral boss and the material
and dimensions is to be in accordance with the Classification's
requirements.
Tiller is to be supplied with rough machined bore and key-way uncut.
Key is supplied by the steering gear manufacturer.

(3) Cylinder, Ram

The cylinders are made of ductile iron casting.
Hydraulic cylinders to be pressure tested according to the
Classification's requirements.
The rams are made of solid carbon steel.
 3

(4) Oil· Tank

Two oil tanks are to be provided with the following fittings :
1 - oil level switch for low level alarm and auto isolation system
1 - oil level gauge with flat glass and self-closing valve
1 - thermometer
1 - oil filling connection
1- air breather.

(5) High Pressure Piping

·seamless steel pipes designed to meet Classification's requirements
are used for all high pressure lines.
The pipe connections are of flanged type.

(6) Main Pump Unit

The domestic hydraulic pumps manufactured by Brueninghaus Hydromatik
GERMANY are used for the pump unit. This pump is of the variable
displacement swash plate type axial piston pump, in which the hydraulic
servo control system is incorporated for enabling to control with
the torque motor.

(7) Main Relief Valve

The dischar·ge capacity of the relief valve is not to be less than
110 percent of the pump capacity which can deliver through it. Under
such condition the rise in pressure is not exceed 10 percent of the
setting pressure.

(8) Torque Motor

The torque motor is a kind of DC multi pole motor. It is connected
to the control lever of the main pump with the link mechanism and
control the angle of the pump cylinder casing.
The pump control lever is extended for manual control that can be
used for gear side control in an emergency.

3. Automatic Isolation System

The steering gear is arranged that in the event of loss of hydraulic fluid from one
system, the. loss can be detected and the defective system is automatically isolated
within 45 seconds so that the other actuating system shall remain fully operational
(50% torque remained).

(1) Construction
This system comprises a standard 2-rams, 4-cylinders steering gear controlled
by one or two pump units. In addition to the steering gear, it would be
necessary to provide the following equipment :
1) 2-Isolation valves
2) 2-Level switches with level "I", "II" & "III" level positions
3) 2-Qil tanks having chamber for level switch and system test valves
4) Electric control panel for automatic isolation system
5) Alarm panel for automatic isolation system (supplied by shipbuilder)

(2) Operation (Refer to the page 13)

Two identical power actuating systems with one or two pump units act
simultaneously in normal operation.
Alarm is given when oil level " I " goes down and level switch is acted.
1) Failure mode operational sequence in both pump units running:
a) If oil level in No. I oil tank goes down to "II" position, No. 2 pump
unit is automatically stopped, and No.1 isolation valve (IB-1) is
automatically energized and hydraulic system associated with No. 2
pump unit is isolated.
b) If the oil loss is in the hydraulic system associated with No.2 pump
unit, steering gear is being carried out by No.1 pump unit and its
two related cylinders (No. 1 & No. 2) giving 50 % torque.
c) On the other hand, if the oil loss in the hydraulic system associated
with No. 1 pump unit, the oil level in No. 1 oil tank goes down to
"III" position and No. 2 pump unit is automatically started. And also
No.1 isolation valve (IB-1) is automatically de-energized No.2
isolation valve (IB-2) is automatically energized and No. 1 pump unit
is automatically stopped, then the hydraulic system associated with
No.1 pump unit is isolated. Steering gear is now being carried out by
No.2 pump unit and its two related cylinders (No. 3 & No. 4)giving 50%
torque.
 5

In case of the oil level of No.2 goes down to "II" position, No.1 and No.2
of pump unit, No.1 and No.2 of isolation valves (IB-1, IB-2) are vice versa
in above sequence.
2) Failure mode operational sequence in one pump unit running with No. 1 pump
unit running and No.2 pump unit stopped if loss of oil occurs, the following
sequence will take place.
a) If the oil level in No.1 oil tank goes down to "II" position, No.1
isolation valve (IB-1) is automatically energized and the hydraulic
system associated with No.2 pump unit is isolated.
b) If the oil loss is in the hydraulic system associated with No.2 pump
unit, steering gear is being carried out by No.1 pump unit and its
two related cylinders (No.1 &No.2) giving 50% torque.
c) On the other hand, if the oil loss is in the hydraulic system
associated with No.1 pump unit, the oil level in No. 1 oil tank goes
down to "III" position and No.2 pump unit is automatically energized,
No.2 isolation valve (IB-2) is automatically energized and No.1 pump
unit is automatically stopped, then the hydraulic system associated
with No.1 pump unit is isolated. Steering gear is now being carried
out by No.2 pump unit using and its two related cylinders (No.3 & No.
4) giving 50 % torque.
If No.2 pump unit running and No.1 pump unit stopped, No.1 and of pump
unit, No.1 and No.2 of isolation valve are vice versa in above
sequence.

(3) System test valve

The system test valves would be operated at pre-sailing check in
order to isolate the main oil tank and drain the float chamber.
The system shall be tested in simulate by them and confirmed they are
operational.

Chapter 1 General

The Single Loop System Steering Gear provides high-accuracy and quick response with
directly/continuously controlling pump swash plate angle by torque motor comparing target
and actual rudder angle then feeding back to pilot stand.
The steering gear thus establish best course-keeping ability and less yaw of the vessel.
This means that the vessel requires less operation of the steering gear and propulsion loss,
therefore can reduce the fuel consumption.

1. Steering Gear
The steering gear is of the 2-ram, 4-cylinder fork type Rapson slide electro-hydraulic,
single loop system equipped with the servo controlled hydraulic pump controlled by
a torque motor.
The steering gear is so designed to move the rudder from 35 degrees on one side to 30
degrees on the other side in 28 seconds with the ship proceeding ahead at full speed.
For emergency, the steering gear can be operated with reduced steering torque
using a couple of opposed cylinders, in this condition the ship's speed and the
tilting angle of the main pump should be restricted.
The steering gear consists of the following main parts. For detailed description of
them, refer to Chapter 2 and the following pages, too.

1) Cylinders, Rams, Ram Pins, and Swivel Blocks

2) Tiller
3) Main Hydraulic Pumps
4) Torque Motors
5) Oil Tank, Filters, and Valves

2. Control of Steering Gear

The steering gear can be controlled in the following methods
1) Auto. pilot control from the bridge
•
2) Follow up control from the bridge
3) Non-follow up control from the bridge
4) Engine side operation with the control lever of the main hydraulic pump
 2

Chapter 2 Steering Gear

1. Construction (See Fig. 1)
1.1 Tiller
The cast steel tiller designed to Classification Society requirements is keyed to the
rudder stock. The torque is transmitted through the ram pin to the tiller with
the swivel block sliding in the tiller fork.

1.2 Cylinder and Ram

The cylinders are made. of spheroidal graphite cast iron.
The rams are made of solid carbon steel. The rams have a high surface finish to
prevent damage to gland packing thus causing oil leakage.
The guide rod is to prevent the rotation of the ram and the bush is provided in
the ram guide.
The four hydraulic cylinders are installed to firmly to the ship.
Opposed hydraulic cylinders are precisely positioned using guide rods.
Two couples of opposed cylinders are connected each other by cylinder struts.
The hydraulic pump units and their electric motors are mounted on the hydraulic
cylinders. Each hydraulic cylinder has a bush in its internal surface to guide the
movement of the ram and sustain the bending force.

1.3 Gland Packing (See Fig. 2)

The gland packing is a V-shaped lip made of canvas-contained synthetic rubber.
The gland packing for each cylinder consists of the following parts.
Header ring 1 piece
V packing 5 pieces
Base ring 1 piece
The V-packing seals with its lip expanding automatically by the internal pressure,
not by the clamping force of the gland. There, tightening the gland retainer will
not require large force.

A dust seal is provided around the gland packing to prevent dust or foreign
matters from entering into the gland part.
 3

1.4 Ram Pin and Swivel Block (See Fig. 3)

The ram pin is made of alloy steel. The swivel block is made of carbon steel.
The ram pin transmits the torque to the tiller through the upper and lower swivel
blocks. The sliding surfaces of the swivel block are equipped with the reinforced
plastic pads.

1.5 Isolation Valve (See Fig. 4)

An .isolation valve is provided with each couple of opposed cylinders owing to
bypass the hydraulic oil between the cylinders. These two valves shall be set to
the Normal position during the normal operation. However, in an emergency the
valve for the isolated cylinders should be set to the bypass position. For the
detailed procedure, see the Chapter 6 and also the instruction board attached to
the steering gear.

1.6 Oil Tank (See Fig. 1 & Fig. 5)

Two(2) sets of oil tank units are installed on port and starboard sides hydraulic
cylinders, respectively.
Each tank is made of welded steel plate, and on which level gauge, level switch,
thermometer, air-breather, filling connection, drain plug and manifold block on
which pilot change-over valve, relief valve and etc. are fitted.

1.7 High Pressure Piping

Seamless steel pipes designed to meet Classification Society requirements are used
for all high pressure lines. The pipe connections are made by flange.

1.8 Air Release and Pressure Gauge Valve (See Fig. 6)

Air release valve is fitted on the top of each cylinder. For the guidance in its use
see Chapter 6.

Gauge valves cylinder pressure are directly mounted to the top of manifold block
on the side wall of the oil tanks.
Cylinder drain plug is screwed on the bottom of each cylinder.
 5

Chapter 3 Hydraulic Pump Unit

1. Construction and Operation of Hydraulic Pump
1.1 Basic Construction (See Fig. 7 & 8)
The hydraulic pump is of the variable displacement swash plate and axial piston
type. It is made compact and light in weight and designed to be suitable for high
-pressure and high-speed operation.

The pump consists of the following main parts :

1) 9 pistons and a cylinder block
2) Valve plate and bearing plate
3) Swash plate
4) Servo cylinder for swash plate control
5) Control servo valve
6) Charge pump
7) Charge relief valve and check valves

The swash plate is controlled by the control valve and the servo cylinder from the
neutral position to 20 degrees at the maximum according to the change of the
control lever. Therefore, discharge direction and displacement can easily be
changed by the control lever operation.

1.2 Basic Operation

Nine (9) pistons are inserted in the cylinder block. The slippers are fitted to the
end of each piston with the ball joints and caulked, being made free to rotate.
The slippers are being pressed to the thrust plate fitted to the swash plate with
a moderate pressure by the retainer guide and the pressure in the piston chamber.
When the driven shaft is rotated, these parts are rotated by the splines fitted to
the cylinder block and the retainer guide.
The slipper rotates along with the thrust plate of the swash plate.
Thus the piston sucks oil during a half turn of the drive shaft according to the
swash plate angle and discharges oil during the remaining half turn.

Suction and discharge .of oil are made through the ports in the bearing plate and
the valve plate. The bearing plate rotates with the cylinder block and slides on
the valve plate.
 6

The splines of the drive shaft and the cylinder are crowned to avoided the
influence of machining errors. The slideways of the bearing plate and the valve
plate are pressed by the cylinder block spring under constant pressure at all times.

As no connecting rod for piston or bearing for cylinder block is provided, the pump
is compact and light in weight and suitable for high-speed rotation with less noise.

1.3 Swash Plate Control (See Fig. 8)

The swash plate angle is controlled by the servo control valve and the servo
cylinder using the hydraulic charge pump.

The Fig. 8 shows both the control lever angle and the swash plate angle are
maximum degree.

With the control lever operation the spool of the servo valve moves and oil
discharged from the charge pump is fed to the servo cylinder through the control
valve and then the swash plate angle is changed.
When the swash plate angle becomes an angle set by the control lever, the spool
of the servo valve returns to the neutral position and keeps the swash plate angle
constant. The control lever can be operated very lightly by using the servo
cylinder.
By leaving the lever free, the lever and the swash plate return to the neutral
position automatically by the bending moment of the swash plate by the force of
inertia of the piston and the spring of the servo cylinder and the action of the
centering spring of the control valve.

1.4 Charge Pump

The charge pump is fitted on the opposite side of the pump drive shaft and
connected to the pump drive shaft.
The pump is used for the swash plate control servo system and replenishment
to the main line.
Take note of to keep the suction pressure of the charge pump less than
250 mmHg vacuum.
 7

2. Accessory
2.1 Coupling of Pump and Motor (See Fig. 9)
ROTEX coupling is used for this pump to permit the centering error of pump
and motor shaft.

Check the coupling periodically and make up or recharge the grease according
to Chapter 8.

2.2 Manifold Block (See Fig. 10)

Associated valves such as the pilot operated valves, main relief valves, isolation/by
pass valves and pressure gauge are to be provided on the manifold block.
The isolation/bypass valve has two positions one for bypassing oil and another for
isolating oil line in case of oil leak from one of the two lines.

2.3 Pilot Operated Valve (See Fig. 11)

The pilot operated valve is provided to prevent the stopping pump from motoring
with counter pressure of the running pump.
The valve is the pilot operated 4-ports center by-pass type.
It changes over by the charge pressure of the main hydraulic pump.

2.4 Main Relief Valve (See Fig. 12)

Two relief valves are provided on the manifold block.
The relief valve is to relief the excessive pressure from the high pressure side to
the low pressure side at the time of abnormally high pressure of main line. The
setting pressure adjustment of the relief valve is set according to Chapter 7.
 8

2.5 Line Filter (See Fig. 13)

The line filter of 20 JJ. paper element is provided on charge pump delivery

line and delivered oil will pass it from outside to inside.

The line filter is equipped with a differential pressure indicator which shows
a differential pressure due to clogging by color ; green showing clean, red
showing the differential pressure becomes 5 bar, a fully red ring appears when
.the pressure becomes 6 bar or over and makes.
The red ring is the sign to replace the element with a new one.

2.6 Oil Cooler (If use)

( 1) In the case of cooler
A cooler is fitted at the back of electric motor for cooling hydraulic oil.
When the temperature of oil becomes low especially, a circuit which oil
by-passes the cooler automatically is fitted.

(2) In the case of motor driven fan cooler

An air blast hydraulic oil cooler is fitted for each hydraulic oil system.
The fan motor of this cooler is operated automatically by detected the oil
temperature of the tank.
Setting Temperature of Temp. Switch.
ON 55 "C
OFF 45 "C

Chapter 4 Single Loop System

1. Control System (See Fig. 14)
Fig. 14 shows a diagram of the single loop control system.
As shown in it, the control system directly controls the pump swash plate angle with
the torque motor through the signal from the auto. pilot and feeds back the final
steering angle to control the steering gear.
It has the following advantages :

1) The composition of the control system is simple and maintenance is easy.

2) As the hydraulic pump swash plate angle is controlled by the torque motor
continuously, high precision control can be made without dead band.

3) With good response and high precision control, superior ship's course keeping
performance is assured with a small amount of steering. This saves fuel
consumption of the main engine.

2. Torque Motor Unit (See Fig. 15)

The torque motor is a kind of DC multi pole motor. It is connected to the control lever
of the main hydraulic pump through link mechanism and controls the pump swash
plate angle. To ensure the torque motor control the linear synchro (or potentiometer)
for feed back the angle is incorporated in the torque motor unit to control the hydraulic
pump swash plate angle continuously through the signal from the auto. pilot.
In the case of control power failure of the torque motor, the swash plate is returned to
the neutral position automatically and the steering gear remains as it is as described
in Chapter 3.

The maximum swash plate angle is set by bridge control (auto. pilot) so that the
rudder is moved from 35 degrees on one side to 30 degrees on the other side in 28
seconds with the ship proceeding ahead at full speed.
(The number of operation pumps are to be in accordance with the specifications.)
This setting has been made at sea trial.
The pump control lever is extended for hand control that can be used for engine side
control in an emergency.
 10

3. Limit Switch
The limit switches are to prevent the steering gear from striking the stopper thus
making the pump main relief valve work in the case where the steering angle exceeds
its maximum due to same accident to the control system. The limit switches are set at
angle a little over the maximum steering angle for both starboard and port, and the
torque motor controlling power is cut by these limit switches.

Therefore, the steering. gear is designed not to strike against the stopper
{normal maximum steering angle + 2 deg.) as the pump swash plate is returned to the
neutral position.

Note that the limit switches will not work at the time of manual control on the engine
side in case of emergency.
 11

Chapter 5 Installation on Board

1. Shipment
The steering gear is delivered in some blocks. Put them on board, taking care not to
give damage to every part, especially to the sliding surface such as the ram surface.

2. Installation
Usually the tiller is delivered earlier than the steering gear and keyed to the rudder
stock and engaged. After that, the steering gear is mounted on the steering engine
seat. The cylinder must be installed with perfect centering.
Install the cylinder correctly as shown in the drawing and adjust the height with the
liners to match the steering engine seat.
The cylinder is fitted to the steering engine seat with the foundation bolts and the
abutment. Tighten the bolts firmly and apply the stopper so that they will not get
loose by vibration.

The hydraulic pipes have been cut, bent and arranged at the works. As they are
delivered after pickling and flushing are made, take care to avoid dust entering into
them before arranging the piping. JIS standard flanges are used for the high pressure
pipes. For the hydraulic pipes, arrange pipe bands at suitable places to avoid vibration.
When installing the pump, pay special attention to the alignment with the motor.
Take care lest the force in the radial and axial directions is applied to the pumps.
The permissible tolerances of the parallel error and inclination error shall be adjusted
within the range shown in Fig. 9.

Make sure of the alignment after the pump unit has been arranged.
After installing the steering gear on board, carefully protect it from dust and wounds.
When the installed steering gear is painted aboard ship, care should be taken that
machined. sliding surfaces are not painted over but rather coated with lubricant or
grease for preventing paint adhesion.
For the details of installation on board, see the instruction Manual of Installation
on Board.
 12

Chapter 6 Operation
1. Preparation for Operation
1.1 Greasing (See Fig. 16)
After assembling has been made, grease the grease fitting part on the tiller fork.

Recommendable grease is No. 2 grade of lithium base or equivalent.

The parts to be grease are collected on the top of the tiller with the piping and
every part is so arranged to be greased at either fore or aft.

Slightly apply grease for rust prevention to surface of guide rod.

Grease every part once a week or so.

1.2 Supplying Hydraulic Oil to Oil Tank and Pump Casing (See Fig. 17)
Hydraulic oil is supplied to the oil tank, hydraulic pump casing. As for the oil
supplied to the hydraulic pump casings, use oil filtered to 10 microns.

Supply oil in the following order :

1) Supply oil to the oil tank from ship's storage tank. (As oil flows into each
part, replenish oil until the oil level comes to the normal oil level range.)

2) Remove the connection at the case drain port at the upper part of the pump
and supply oil filtered to 10 microns. Supply oil in the casing up to about 80
percent.

3) Check the level of oil in the tank and replenish oil if reduced.

4) Fully apply hydraulic oil to ram surface.

 13

1.3 Starting the Pump

Oil has been supplied to each pump casing in 1.2. Operate the hydraulic pump
as following instructions :

1) Before starting the pump, make sure all the valves attached to the tank are
open.

2) Shut off the electric power of the control amplifier from the starter for the
hydraulic pump motor of the steering gear. Make sure the pump is returned
to the neutral position by the spring by operating the hand control lever fitted
to the pump.

3) Remove the coupling cover of the pump, rotate the pump by hand in the
arrow direction and make sure the pump rotates smoothly.

4) Fit the coupling cover again, rotate the motor for a moment and make sure
the pump rotates in the direction of the arrow shown on the nameplate of the
pump. If rotates reversely, exchange the wires of the motor.

5) After making sure of the correct direction of the rotation, inch the motor
several times and make sure.
a) the charge pump pressure (1.18 MPa and over) increase and that
b) there is no abnormal noise or vibration.

6) If nothing is wrong with the pump at the time of inching, start the pump
while keeping the pump control lever neutral, let it run without load for about
ten minutes and make sure of the above a) and b).

Pay attention especially when the hydraulic pump is started at low

tern perature such as winter season (below 10 "C approx.).

If the oil temperature is low, continue this no-load running further until it
becomes about 30 "C.
 14

1.4 Supplying Hydraulic Oil to the Cylinders

Supply the oil to the cylinders by the charge pump incorporated in the main
pump as following procedure.

1) Oil filling should be done one by one with releasing air inside cylinder by air
release valve, not simultaneously. Oil filling shall be also done with the
associated isolation valve to be isolated position("!" position).

2) The cylinder air release valve is adjusted to keep the charge pressure. at
0.69 MPa and above.
The charge pressure must be keep minimum 0.69 MPa at steady condition to
lubricate the sliding parts of the pump.

3) When the oil bled from the air release valve, the air release valve is close.

4) Supply the oil for the other cylinder in order as same procedure.

5) After supplying the oil for all cylinders. All isolation valves are should be set
to the Normal position ("N" position).
And tilt the pumps hand control lever for port and starboard direction and
confirm the pump is in good order.

6) Make sure the ram does not move at the time of neutral running of the pump.

After that, move the ram slowly by operating the pump hand control lever
port and starboard direction.

7) Release the air from the cylinder completely.

Thus starting the pump and releasing air have been completed and operation is
ready.
 15

1.5 Purging Air from the Hydraulic Circuit (See Fig.6)

The air purging operation mentioned in Section 1.4 is not sufficient, since there
might be still a large amount of air remaining in the circuit and cylinders. This
rich status may cause abnormal sound when controlling the pump tilting angle.
In this case, operate the steering gear by using the control lever to move the
rudder slowly to the position of about 30 degrees on one side and then move it to
the other side in order to purge air from the system. Continue this operation for
several turns of the rudder until the rams can move smoothly. In this operation,
make sure that the air release valve of the cylinder at the pressure side (the side
supplied with oil) is kept opened (note that the pressure side will change depend-
ing on the moving direction of the rudder). This air purging operation should be
done with both pumps, but using one pump at a time. During and after the air
purging operation, check the oil tank, and replenish the tank if necessary.

Caution 1 Never open the air release valve of the cylinder into which the ram
is entering. Opening the valve of such the cylinder will cause brea
thing a large amount of air into the system.
Caution 2 Long time operation of the pump should be not done until the
purging operation is completed.
 16

2. Operation
The steering gear is now ready for operation. Run the pumps in the number as
specified in the ship's specifications. They are 'controlled by the pilot stand at the
bridge.

For the details of combined operation with the pilot, see the Instruction Manual of the
Auto. Pilot.

When the pump stops running temporarily (about 10 hours and over) at the ship is in
port for instance, make sure of air release again according to the instructions given
above and start the operation after increasing the oil temperature to about 30 "C or
more at neutral running of the pump.

3. Emergency Operation
In case normal steering is not available at wheel house as a trouble is happened,
operate according to the "PROCEDURE OF EMERGENCY OPERATION FOR
REMOTE STEERING CONTROL SYSTEM" made by auto. pilot maker.

In case auto. pilot can not be used by any reason carry out emergency engine side
operation according to the following order keeping in good contact between bridge and
steering room.

3.1 Emergency Engine Side Operation (See Fig. 17)

(1) Shut off the power supplied to the control amplifier from the starter for the
hydraulic pump motor.

(2) In the emergency engine side operation, operate the pump hand control lever
(Fig. 18) according to the instruction plate on the control lever.
If the desired steering angle is obtained, return the pump control lever to the
neutral position.
 17

(3) By releasing the control lever, it is automatically returned to the neutral

position as described in Chapter 3.
However as it takes much time for the pump having larger capacity to be
returned the control lever to the neutral position it is difficult to be coincided
with the steering angle. In that case return the control lever to the neutral
position forcibly by manually.

(4) In the case of engine side operation, the safety device with the limit switch
set near 35 degrees does not work.
Therefore, take care the steering angle should not exceed 35 degrees.

3.2 Emergency Operation when the Piping System is damaged (See Fig. 17)
This steering gear has two separate hydraulic systems.
If it were single failure in any part of alternative hydraulic system, it would be
possible to operate one by using the normal hydraulic system to operate by-pass
position the isolation valve of the defective hydraulic system.
(1) If the ship is maintaining full speed, rudder angle must not exceed 15 degrees.
If rudder angle of 35 degrees is required, the ship's speed must be reduced to
approximately the half of the full speed, but make sure to keep it at least 7
knot.
(2) Correctly operate the hydraulic pump and valves as instructed in Fig.17 and
the instruction plate .on the steering gear.
 18

4. Hydraulic Oil
Mineral oil with high acid-resistibility and high lubricant quality should be used.
Same brand oil should be used at replenishing and never mixed different ones.
Never use vegetable oil even for replenishment. Recommended oils are listed as follows.
If oil not mentioned in the list, it should be equivalent to one of the brands.

Chapter 7 Adjustment of Relief Valve and Temp. Switch

1. Setting Pressure and Temperature
Main relief valves 27.5 MPa
Charge relief valves 1.47 ~ 1.96 MPa

2. Adjustment of Main Relief Valve

The adjusting pressure has been set before delivery from our works.
Re-adjustment is not required accordingly.
However, it is necessary to confirm the operation on board together with the pressure
test of the hydraulic pipes, gaskets, etc., whose procedures are as follows;

(1) Preparation :
The main relief valve test will be carried out by means of the pump control lever.

a) Shut off the power supplied to the control amplifier from the starter for the
.hydraulic pump motor.

b) Depending on the main relief valve subject to confirmation, the hydraulic

pump and the stop valves shall be operate as. shown "Procedure of adjusting
main relief valve" in Fig. 17.

c) Start the electric motor and hydraulic pump, and operate the steering gear to
moved 35 degrees by the pump control lever.
 20

(2) Main relief valve operation

a) When the rudder angle is over 35 degrees move the rudder slowly.
Since the ram reaches the stopper at the bottom of the cylinder, the pressure
will rise.

b) Confirm the adjusting pressure of the relief valve by observing the movement
of the pointer of the pressure gauge. (The adjusting pressure is marked with
red on the dial plate of the pressure gauge.)

c) The operation of the relief valve shall not· exceed 30 seconds at a time because
the electric motor may cause burning.

(3) Adjustment of main relief valve

If the adjusting pressure of the relief valve is differed with the designed one,
adjust it in the following manners :
The assembly section is shown in Fig. 12.
a) Loosen the lock nut 2.

b) Adjust the pressure by turning the adjust bolt 3. Pressure will rise if screw
is turned to right and pressure will drop if turned to left.

c) After the adjustment, fix the lock nut as original.

When con!rrming the main relief valve, check for oil leakage and abnormality
in each part of the steering gear.
After, the test is over, put the stop valve, by-pass valve, power unit, etc. to
the original condition.

2. Exchange the Gland Packing

When oil leaks from the gland packing deteriorated with age or for some reason,
exchange it in the following way referring to Fig. 2 :

1) Removiiig the packing

Remove the gland follower and then the gland packing, taking care not to damage
the ram surface.
The header ring and the base ring can be used so long as they are not damaged.

2) Fitting the packing

Before inserting new packings, thoroughly remove dirt and impurities sticked on the
interior of the stuffing box and the ram surface.
The spare packing having a cut can be exchanged without drawing out the ram.
If the packing is hard, make it soft by hand rubbing.
Insert the base ring (male adapter) inward.
Insert the packing inward by fingers or a bamboo spatula to support the packing.
Wind the new packing to the ram. At the moment, confirm that the section is
correctly met.
Follow the same manner subsequent to the second one.
As shown in Fig. 2, shift the cuts 90 degrees each when fitting the packings.
Five packings are required for each cylinder.
Insert the header ring (female adapter) inward.

3) Clamping the gland

Take care not to clamp the gland one-sidedly.
The suitable clearance between the cylinder and the packing gland is shown in
Fig. 2.
As mentioned before, as this ''V" packing is designed to seal automatically by the
lip of the packing expanded by the internal pressure, no large clamping force is
required.
 26

3. Examination of Hydraulic Oil

Most hydraulic oil systems are prone to a certain amount of aeration and this action
results in deterioration of the oil characteristics after lengthy operation of the system.
If this condition is allowed to continue too long then excessive wear within the pump
can happen. To avoid this a periodical examination of the oil is essential. The oil
should be examined at least once every six months when conditions to look for would
be
a) Any change of oil color to brownish black.
b) Any visible sings of impurities in oil at tank.
c) Any emulsification.
In addition to above visual inspection, most oil suppliers will analyse samples of used
oil, and from the results give their recommendations.
This service could be used to advantage by submitting at regular intervals (every six
months) a sample of oil for analysis.
If the result exceeds the renewal standard, renew the hydraulic oil. When the existing
oil has to be replaced by new oil, care must be taken to use the same brand or
equivalent grade of oil. In this case also the procedure for charging and venting the
system should be adhered to. See Chapter 6, section 1.

5. Dismantiling and Assembling of Hydraulic Pump

Overhauling snd assembling a hydraulic pump will require special cares and well-
trained skill. It should therefore be left to specialists of the pump manufacturer.

6. Maintenance Manual for Torque Motor (See Fig. 15)

·This steering gear uses a torque motor supplied from the manufacturer of the auto
pilot system. Adjustment of the torque motor (adjusting the turning speed of the
rudder) has been done before the delivery of the vessel.
For trouble shooting and maintenance of the torque motor, consult the manufacturer of
the auto pilot system.
 28

Chapter 9 Trouble Shooting Guide

1. Judgement of Trouble Origin
The steering apparatus consists of steering gear and bridge control (auto. pilot). So in
case steering trouble ia happened, first of all, judge which is something wrong according
to the flow chart shown below. When auto. pilot is something wrong, see operating
hand book of auto. pilot.

Sometimes element to be changed in early stages at the first time of element is
. needed within 1000 hours since second time after entering service following
maintenance to be carried out.

(a) An extent of pollution or analysis of component of hydraulic. oil to be

requested oil maker, consult with hydraulic oil maker or steering gear maker,
if it is not good condition.

(b) Consult with steering gear maker if a grain of metal is found at the
examination of a foreign matter fitted to the element.

(c) [n case hydraulic oil is polluted or is dirty there is a method that oil is
cleaned by flushing cast with the filter of absolute 3 microns, consult with
hydraulic oil maker or steering gear maker about working plan.

Chapter 10 Dismantling Procedures for Pintle Bearing Inspection

When inspecting the pintle, the rudder plate must be jacked up 400 to 500 mm.
However, it cannot be done as it is because the arms of fork-typed tiller has inserted
the ram at upper and lower parts.
Therefore, dismantle the steering gear in the following procedures by referring
to Fig. 3 :

a) Remove all the connecting levers above the tiller.

b) Remove the guide and guide rod.

c) Remove the set pin for ram pin.

d) Jack up the ram pin from the lower part and pull out it completely upwards.

e) Carefully and slowly turn the tiller and rudder plate (rudder stock) by means of a
which of the dock up to the 90' position as shown in Fig. 3.
Caution : For the rudder plate not allowing the 90' turn due to the hull
construction, remove the key, jack up only the tiller and turn it up to
the 90' position.

f) . Jack up the rudder plate (rudder stock) and the tiller in such condition, and inspect
the pintle portion.

g) After the inspection, assemble the steering gear in reverse order to that of
disassembly. At the moment, the set pin for ram pin without fail.

 Chapter 1 General

· This instruction manual is described for automatic isolation system of

Single Loop System Steering gear.

Also refer to the instruction manual for steering gear together with this one.
The automatic isolation system is consist of automatic isolation valves, servo pump
unit and level switch. The electric control panel is supplied by shipbuilder.

In the loss of hydraulic oil from one system, which is detected by the level switch
of tank, then the defected system is automatically isolated within 45 seconds so
that the other actuating system shall remain fully operational (50% torque
remained).
In this case, the torque is decrease about half of rated· one, then the ship's speed
or maximum rudder angle must be reduced.

Chapter 2 Hydraulic System (Refer to Fig. I )

The hydraulic system is divided into two systems and interconnected with automatic
isolation valves. The valves are arranged for each fore and aft cylinder unit to by
pass them. These valves are of hydraulic operated four ports valve controlled by
the servo pump solenoid valve. The oil tank is equipped with level switch and test

valve.

-J-
Chapter 3 System Components

1. Isolation Valve (Refer to Fig. II)

The isolation valve is of hydraulic operated four poets spool type valve and fitted

on the manifold valve block directly. Refer to the instruction manual of the.
steering gear for the details of the manifold valve block. This valve is fitted on
interconnection line of No.1 and No.2 system to isolate the defected system and
also. to by-pass the oil of defected system.

2. Level Switch (Refer to Fig. ill)

Each one set of level switch is provided for No.1 and No.2 oil tank.
The level switch is of reed type having three floats and three reed switches.

The level switch is provided in the separated chamber and can be tested by the
test valve without changing the main oil tank level.

-2-
Chapter 4 Operating Sequence (Refer to Fig. IV)

Two identical power actuating systems with one or two units act simultaneously in.
normal operation.

Alarm is given oil level " I " goes down and level switch is acted.

1) Failure mode operational sequence in both power units running

a) If oil level in No.1 oil tank goes down to "II" position, No.2 power unit is

automatically stopped and No.1 isolating valve (IB-1) is automatically energized

and hydraulic system associated with No.2 power unit is isolated.
b) If the oil loss is in the hydraulic system associated with No.2 power unit,
steering gear is being carried out by No.1 power unit and its two related
cylinders (No.1 & No.2) giving 50% torque.
c) On the other hand, if the oil loss is in the hydraulic system associated with
No.1 power unit, the oil level in No.1 oil tank goes down to "ill" position and

No,2 power unit is automatically started. And also No.1 isolating valve (ffi-1)
is automatically de-energized, No.2 isolating valve (ffi-2) is automatically
energized and No.1 power unit is automatically stopped, then the hydraulic
system associated with No.1 power unit is isolated. Steering gear is now being
Carried out by No.2 system unit and its two related cylinders (No.3 & No.4)
giving 50% torque.
2) Failure mode operational sequence in one power unit running with No.1 power
unit running and No.2 power unit stopped if loss of oil occurs, the following
sequence will take place.
a) If the oil level in No.1 oil tank goes down to "II" position, No.1 isolating valve

(IB-1) is automatically energized and the hydraulic system associated with No.2
power unit is isolated.
b) If the oil loss is in the hydraulic system associated with No.2 power unit,
steering gear is being carried out by No.1 power unit and its two related
cylinders (No.1 & No.2) giving 50% torque.

~-------- ~ -----

c) On the other hand,· if the oil loss is in the hydraulic system associated with
No.1 power unit, the oil level in No.1 oil tank goes down to "III;" position and

No.2 power unit is automatically started. And also No.1 isolating valve (IB-1)
is automatically de-energized, No.2 isolating valve (IB-2) is automatically
energized and No.1 power unit is automatically stopped, then the hydraulic
system associated with No.1 power unit is isolated. Steering gear is now being
Carried out by No.2 power unit and its two related cylinders (No.3 & No.4)
giving 50% torque.

Chapter 5 Emergency Operation during Sea Going

Mter isolated automatically therein before, the ship's speed and steering angle of
rudder must be reduced because the steering torque is decreased about half of rated
one.
And fill the hydraulic oil to normal for operating system from storage tank.
And also make sure that the steering is operated with two cylinders and manual
isolation valve and by-pass valve are set according to the steering gear condition.
