A Engine Oil : Oil used in the engine should have an American Petroleum Institute (API) service
classification and Proper SAE Engine Oil according to the ambient temperature as shown above.
A With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use
of a low-sulfur fuel on on-road vehicle engines. When an off-road vehicle engine runs on a high-sulfur
fuel, it is advisable to employ the CF, CD or CE lubricating oil with a high total base number. If the CF-
4 or CG-4 lubricating oil is used with a high-sulfur fuel, change the lubricating oil at shorter intervals.
A Lubricating oil recommended when a low-sulfur or high-sulfur fuel is employed.
O : Recommendable X : Not Recommendable

A Transmission Oil : The oil used to lubricate the transmission is also used as hydraulic fluid. To insure
proper operation of the hydraulic system and complete lubrication of the transmission, it is important
that a multi-grade transmission fluid be used in this system. We recommend the use of KUBOTA SUPER
UDT fluid for optimum protection and performance.
Do not mix different brands together.
A Indicated capacity of water and oil are manufacture's estimate.

Flush Cooling System and Changing Coolant

A Do not remove the radiator cap (1) while coolant is hot.


When cool, slowly rotate cap to the first stop and allow
sufficient time for excess pressure to escape before
removing the cap completely.
1. Stop the engine and let cool down.
2. To drain the coolant, remove the radiator hose (3) and radiator
cap. The radiator cap (1) must be removed to completely drain
the coolant.
3. After all coolant is drained, install the hose (3) securely.
4. Fill with clean water and cooling system cleaner.
5. Follow directions of the cleaner instruction.
6. After flushing, fill with clean water and anti-freeze until the
coolant level is just below the radiator cap.
7. Fill with clean water and anti-freeze up to the upper line of
recovery tank (2).
8. Install the radiator cap (1) securely.
9. Start and operate the engine for a few minutes.
10. Stop the engine. Check coolant level and add coolant if
necessary.

A Do not start engine without coolant.


A Use clean, fresh water and anti-freeze to fill the radiator.
A When the anti-freeze is mixed with water, the anti-freeze
mixing ratio must be less than 50 %.
A Securely tighten radiator cap (1). If the cap is loose or
improperly fitted, water may leak out and the engine could
overheat.

A On cabin type machines, fresh water circulates through


the heater. This means that one more liter or so of fresh
water is required.
In changing fresh water, pour fresh water up to the filter
port of the recovery tank. Turn ON the heater (shift the
temperature control lever toward WARM), and run the
engine for a while in order to warm fresh water. Then stop
the engine.
When fresh water has cooled down, some of the fresh
water in the recovery tank is sucked. Now the recovery
tank is appropriately filled with fresh water.

Flush Cooling System and Changing Coolant (Continued)


B Anti-Freeze

A When using antifreeze, put on some protection such as


rubber gloves (Antifreeze contains position.).
A If should drink antifreeze, throw up at once and take
medical attention.
A When antifreeze comes in contact with the skin or
clothing, wash it off immediately.
A Do not mix different types of Antifreeze.
The mixture can produce chemical reaction causing
harmful substances.
A Antifreeze is extremely flammable and explosive under
certain conditions. Keep fire and children away from
antifreeze.
A When draining fluids from the engine, place some
container underneath the engine body.
A Do not pour waste onto the grounds, down a drain, or into
any water source.
A Also, observe the relevant environmental protection
regulations when disposing of antifreeze.
If it freezes, coolant can damage the cylinders and radiator. If
the ambient temperature falls below 0 or before a long-term
storage, let out cooling water completely, or mix fresh water with
long-life coolant and fill the radiator and reserve tank with the
mixture.
1. Long-life coolant (hereafter LLC) comes in several types. Use
ethylene glycol (EG) type for this engine.
2. Before employing LLC-mixed cooling water, fill the radiator
with fresh water and empty it again.
Repeat this procedure 2 or 3 times to clean up the inside.
3. Mixing the LLC
Put the LLC in cooling water in the percentage (%) for a target
temperature. When mixing, stir it up well, and then fill into the
radiator.
4. The procedure for the mixing of water and antifreeze differs
according to the make of the antifreeze and the ambient
temperature. Refer to SAE J1034 standard, more specifically
also to SAE J814c.

A When the antifreeze is mixed with water, the antifreeze


mixing ratio must be less than 50 %.
Freeze Point Boiling Point*
Vol % Anti-freeze

40 -24 106

50 -37 108

*At 1.013 x 1000000 Pa (760 mmHg) pressure (atmospheric).


A higher boiling point is obtained by using a radiator pressure cap
which permits the development of pressure within the cooling
system.

KiSC issued 04, 2006 A


G-32
ME5700, WSM GENERAL

5. Adding the LLC


(1) Add only water if the mixture reduces in amount by
evaporation.
(2) If there is a mixture leak, add the LLC of the same
manufacture and type in the same mixture percentage.
*Never add any long-life coolant of different manufacture.
(Different brands may have different additive components, and
the engine may fail to perform as specified.)
6. When the LLC is mixed, do not employ any radiator cleaning
agent. The LLC contains anticorrosive agent. If mixed with
the cleaning agent, sludge may build up, adversely affecting
the engine parts.
7. Kubota's genuine long-life coolant has a service life of 2 years.
Be sure to change the coolant every 2 years.

A The above data represents industry standards that


necessitate a minimum glycol content in the concentrated
anti-freeze.
A When the coolant level drops due to evaporation, add
water only to keep the antifreeze mixing ratio less than 50
%. In case of leakage, add antifreeze and water in the
specified mixing ratio before filling in to the radiator.

[5] TIRE LIQUID INJECTION


Auxiliary weights can be used to increase traction force for plowing in fields or clayey grounds.
Another way is to inject water or another liquid, such as a calcium chloride solution in the tires. Water must not be
used in winter since it freezes at 0 (32 ). The calcium chloride solution will not freeze and moreover, affords
higher effect than water since its specific gravity is higher than that of water by about 20 %. Below is an explanation
of calcium chloride solution injection.

A Do not fill the front tires with liquid.


0000001190E
Preparation of Calcium Chloride Solution

A When making a calcium chloride solution, do not pour


water over calcium chloride since this results in chemical
reaction which will cause high temperature. Instead add
a small amount of calcium chloride to the water at a time
until the desired solution is achieved.

Injection

A When a calcium chloride solution is used, cool it before


pouring it into the tire.
A Do not fill tires with water or solution more than 75 % of
full capacity (to the valve stem level).
A To avoid damage of transmission, do not use rear wheel
weights and liquid ballast at the same time.
The following four ways can be used to inject water or a calcium
chloride solution into tires.
1. Gravity injection (Fig. 1)
2. Pump injection (Fig. 2)
3. Pressure tank injection (Fig. 3)
4. Injection directly from tap (only when water is being used).

A Once injection is completed, reset the air valve, and pump


air into the tire to the specified pressure.

Draining Water or Solution


1. Lift the rear tires off the ground.
2. Turn the tire so that the air valve is at the bottom.
3. Remove the air valve, and drain liquid (liquid can only be
drained to the level of the valve and liquid under that level
remains inside).
4. To drain liquid completely, use the injector (1), and direct
compressed air into the tire to force out the liquid through the
injector's vent (3).

(1) Rocker Arm and Rocker
Arm Shaft
(2) Oil Pressure Switch
(3) Camshaft
(4) Piston
(5) Oil Filter Cartridge
(6) Relief Valve
(7) Oil Strainer
(8) Oil Pump

This engine's lubricating system consists of oil strainer (7), oil pump (8), relief valve (6), oil filter cartridge (5) and
oil pressure switch (2). The oil pump sucks lubricating oil from the oil pan through the oil strainer (7) and the oil flows
down to the filter cartridge (5), where it is further filtered. Then the oil is forced to crankshaft, connecting rods, idle
gear, camshaft and rocker arm shaft (1) to lubricate each part.
Some part of oil, splashed by the crankshaft or leaking and dropping from gaps of each part, lubricates these parts:
pistons (4), cylinders, small ends of connecting rods, tappets, pushrods, inlet and exhaust valves and timing gears.

(6) Cylinder Block Water
Jacket

The cooling system consists of a radiator (1), a centrifugal water pump (4), a cooling fan (2) and a thermostat (3).
The water is cooled as it flows through the radiator core, and the cooling air through the radiator core by cooling
fan (2).
The water pump receives water from the radiator or from the cylinder head and force it into the cylinder block.
The thermostat (3) opens or closes according to the water temperature. When the water temperature is high, the
thermostat (3) opens to allow the water to flow from the cylinder head to the radiator (1). When the water temperature
is low, the thermostat close to flow the water only to the water pump (4).
The opening temperature of the thermostat (3) is approx. 71 (159.8 ).

3. FUEL SYSTEM
(1) Fuel Tank
(2) Fuel Overflow Pipe
(3) Injection Nozzle
(4) Injection Pipe
(5) Injection Pump
(6) Fuel Lift Pump
(7) Fuel Filter

Fuel from the fuel tank (1) passes through the fuel filter (7), and then enters the injection pump (5) after impurities
such as dirt, water, etc. are removed.
The fuel pressurized by the injection pump (5) to the opening pressure (13.73 to 14.71 MPa, 140 to 150 ,
1991 to 2062 psi), of the injection nozzle (3) is injected into the combustion chamber.
Part of the fuel fed to the injection nozzle (3) lubricates the moving parts of the plunger inside the nozzle, then
returns to the fuel tank (1) through the fuel overflow pipe (2) from the upper part of the nozzle holder.

As shown in the figure above, the PTO propeller shaft 1 (1) is always rotated while the engine runs.
The PTO clutch pack (2) has seven clutch discs (7), seven drive plates (8) and one pressure plate (9). The clutch
piston (6) actuated by hydraulic from PTO clutch valve, tightly presses the clutch discs (7) and drive plates (8) toward
the pressure plate (9).
As a result, the rotation of the PTO propeller shaft is transmitted to the gear shaft (4) through the PTO clutch pack
(2).
The PTO clutch valve can be in a semi-clutching state by means of the modulating valve. Thereby, the PTO clutch
is engaged very smoothly.

B PTO Clutch "Engaged"
The oil from power steering controller flows into the
clutch valve (1). When the PTO shift lever is set at the
"Engaged" position, the spool (2) is turned to A
position, then oil flows through the spool (2) into the
modulating valve and the clutch pack. Oil entering the
clutch pack pushes the piston (4) to engage the clutch
pack. The modulating valve (12) absorbs the engaging
shock of the clutch pack.

B PTO Clutch "Disengaged"


When the PTO shift lever is set at the "Disengaged"
position, the spool (2) is turned to B position, then the oil
from the power steering controller is stopped by the
spool (2) and the oil in the PTO clutch pack drained into
the tank. Thus the piston (4) is pushed back by the
return spring (8).
When the piston (4) is pushed back, the brake plate
(7) is also moved to contact the brake disc (6) so as to
stop the rotation and the drag of the PTO shaft.

The rear axles are the final mechanism which transmit power from the transmission to the rear wheels. Direction
of power transmitted is changed at a right angle by the differential gear (10) and, at the same time, speed is reduced.
It is further reduced by the planetary gear to drive the rear axles.
The rear axles (1) are semi-floating type with the ball bearing between the rear axle (1) and rear axle case (2), which
support the rear wheel load as well as transmitting power to the rear wheel. They withstand all the forces caused by
tire rotation and side skidding.

The front axle of the 4WD is constructed as shown above. Power is transmitted from the transmission through the
propeller shaft (24) and to the bevel pinion shaft (21), then to the spiral bevel gear (5) after that to the differential gear.
The power through the differential is transmitted to the differential yoke shaft (4), and to the bevel gear shaft (15)
in the bevel gear case (1).
The revolution is greatly reduced by the bevel gears (17), (13), then the power is transmitted to the axle (12).
The differential system allows each wheel to rotate at a different speed to make turning easier.

B Hydraulic Oil Flow
When the engine starts, the hydraulic pump (4) of the
power steering system pressure-feeds the oil drawn
from the transmission case through the suction pipe.
The oil which has entered steering controller (2) is
directed to control valve (5).
As the steering wheel is turned, control valve (5)
operates and the oil passes through gerotor (6) and into
steering cylinder (1). The cylinder rod then moves to
control the directional movement of the front wheels.
Return oil from steering cylinder (1) passes through
control valve (5) is sent to the PTO clutch valve and
shuttle valve.
When the engine is not operating, and the steering
wheel is turned, gerotor (6) rotates to supply oil to
steering cylinder (1). Thus the machine can be steered
manually.

[2] DRAFT CONTROL


Draft control is a system which maintain a constant traction load, and is suited for the work which needs heavy
traction load such as plowing.
The implement is automatically raised when its traction load is increased, and lowers when the traction load is
decreased. By maintaining a constant load level, it prevents the tractor from slipping and being loaded excessively.
The setting traction load can be adjusted by changing the position of the draft control lever (5).
The draft control system uses the same control valve as the position control system. The traction load applied to
the tractor is sensed and is fed back to the control valve by means of the other linkage mechanism.
0000001719E
With this type of draft control, operation is as
described below according to the position of the draft
control lever.
1. When the draft control lever is positioned in the
floating range, the implement lowers to the ground.
2. When the draft control lever is positioned in the draft
control range, work is performed as follows.
-As the traction load applied to the tractor from the
implement increases, the implement is raised.
-As the traction load decreases, the implement
lowers to the position at which it matches the setting
traction load.
3. When the implement is raised as described in 2
above, the force to raise the implement is applied to
the rear wheels so that the ground pressure of the
wheels is momentarily increased to prevent
slippage.
(Reference)
A When the draft control is used, the position control
lever should be set at "FLOATING" range.
A If the position control lever is set at working range,
both control systems operate performing mix control
system. (See "(3) Mixed Control")

The traction load applied to the tractor from the implement act as a torsional force to the torsion bar (6) via the top
link (7) and top link holder (5). When the torsion bar (6) is twisted, its displacement is transmitted to the feedback
shaft (3) to rotate via the feedback rod (4). The feedback shaft rotates and push the link 1 (10) to rotate the link 2 (8).
The end of the spool drive lever (9) is connected to the link 2 (8) and the other end is hold by the fixed arm (13), pulling
out or pushing in the spool (12) by the rotation of the link 2 (8).
The spring (11) is pulling the spool drive lever (9) to keep the link 1 (10) coming in contact with the feedback shaft
(3).
The angle of the link 1 (10) is controlled by the draft control lever (1) via the lever shaft (2).

[3] MIXED CONTROL


Mixed control is a system combining position control
with draft control.
When traction load increases, the draft control
functions to raise the lift arms (implement). When
traction load reduces, the lift arms (implement) lower to
the height set by the position control only, when traction
load increases, slippage or engine stop may occur
unless the implement is raised.
With the draft control only, plowing depth cannot be
kept constant if soil hardness changes greatly.
The mixed control serves to eliminate such
disadvantages.

8. OIL COOLER RELIEF VALVE


The oil cooler relief valve is located on the right hand
side of the clutch housing case.
This valve uses a direct acting relief valve, which is
suitable for low volume and less frequent operations.
This valve has a fast response, makes it ideal for
relieving shock pressure caused by engine starting.
If pressure in the oil cooler line becomes to great, oil
pressure forces the ball (5) off the seat of valve body (3),
compressing the coil spring (2) and allows oil to flow to
the transmission case through the T port.

4. CHECKING, DISASSEMBLING AND SERVICING

A To avoid accidental short circuit, be sure to attach the positive cable to the positive terminal before the
negative cable is attached to the negative terminal.
A Never remove the battery cap while the engine is running.
A Keep electrolyte away from eyes, hands and clothes. If you are spattered with it, wash it away
completely with water immediately.
A Keep open sparks and flames away from the battery at all times. Hydrogen gas mixed with oxygen
becomes very explosive.

A If the machine is to be operated for a short time without battery (using a slave battery for starting), use
additional current (lights) while engine is running and insulate terminal of battery. If this advice is
disregarded, damage to alternator and regulator may result.
A Insulate terminal of battery. If this advice is disregarded, damage to alternator and regulator may result.

Battery Specific Gravity


1. Check the specific gravity of the electrolyte in each cell with a
hydrometer.
2. When the electrolyte temperature differs from that at which the
hydrometer was calibrated, correct the specific gravity reading
following the formula mentioned in (Reference).
3. If the specific gravity is less than 1.215 (after it is corrected for
temperature), charge or replace the battery.
4. If the specific gravity differs between any two cells by more
than 0.05, replace the battery.

A Hold the hydrometer tube vertical without removing it


from the electrolyte.
A Do not suck too much electrolyte into the tube.
A Allow the float to move freely and hold the hydrometer at
eye level.
A The hydrometer reading must be taken at the highest
electrolyte level.

(Reference)
A Specific gravity slightly varies with temperature. To be exact,
the specific gravity decreases by 0.0007 with an increase of
1 (0.0004 with an increase of 1 ) in temperature, and
increases by 0.0007 with a decreases of 1 (0.0004 with a
decrease of 1 ).
Therefore, using 20 (68 ) as a reference, the specific
gravity reading must be corrected by the following formula :
-Specific gravity at 20 = Measured value + 0.0007 x
(electrolyte temperature - 20 )
-Specific gravity at 68 = Measured value + 0.0004 x
(electrolyte temperature - 68 )

Recharging

A When the battery is being activated, hydrogen and


oxygen gases in the battery are extremely explosive.
Keep open sparks and flames away from the battery at all
times, especially when charging the battery.
A When charging battery, remove battery vent plugs.
A When disconnecting the cable from the battery, start with
the negative terminal first. When connecting the cable to
the battery, start with the positive terminal first.
A Never check battery charge by placing a metal object
across the posts.
A Use a voltmeter or hydrometer.
1) Slow Charging
1. Add distilled water if the electrolyte level is low. When
charging, the amount of electrolyte should be slightly lower
than the specified level to prevent overflow.
2. Connect the battery to the charging unit, following the
manufacture's instructions.
3. As the electrolyte generates gas while charging, remove all
port caps.
4. The electrolyte temperature must not exceed 40 (105 )
during charging.
If it exceed 40 (105 ), decrease the charging amperage
or stop charging for a while.
5. When charging several batteries in series, charge at the rate
of the smallest battery in the line.
2) Quick Charging
1. Determine the proper charging current and charging time with
the tester attached to the quick charger.
2. Determine the proper charging current as 1/1 of the battery
capacity. If the battery capacity exceeds 50 Ah, consider 50 A
as the maximum.
B Precaution for Operating a Quick Charger
A Operation with a quick charger differs according to the type.
Consult the instruction manual and use accordingly.

Directions for Storage


1. When shutting down the tractor for long periods of time,
remove the battery from the tractor, adjust the electrolyte to
the proper level, and after fully charging, store the battery in a
well ventilated placed where it is not exposed to direct
sunlight.
2. Since the battery self-discharges by approx. 0.5 % per day
even in storage, it must be once every two months in cold
season.
3. When storaging the battery mounted on the tractor, disconnect
the ground cable from the battery's negative terminal post.

4. PRECAUTIONS AT REPAIRING REFRIGERANT CYCLE


When checking or repairing the air conditioning system, the following precautions and rules must be observed. And
it is of first importance that no other personnel than a well-trained serviceman should be allow to handle the
refrigerant.

A Since direct contact of the liquid refrigerant with your skin will cause frostbite, always be careful when
handling the refrigerant. Always wear goggles to protect your eyes when working around the system.
A The refrigerant service container has a safe strength. However, if handled incorrectly, it will explode.
Therefore, always follow the instructions on the label. In particular, never heat the refrigerant container
above 40 (104 ) or drop it from a high height.
A Do not steam clean on the system, especially condenser since excessively high pressure will build up
in the system, resulting in explosion of the system.
A If you improperly connect the hose between the service valve of compressor and gauge manifold, or
incorrectly handle the valves, the refrigerant service container or charging hose will explode. When
connecting the hose or handling the valve, be sure to check the high pressure side or low pressure side.
A In case the refrigerant is charged while the compressor is operated, do not open the high pressure valve
of the gauge manifold.
A Beware of the toxicity of the gas. The gas is harmless and nontoxic in its original state, however it
produces a toxic substance when it comes in contact with high temperature parts and decomposes.
A Do not heat the service can unless necessary. When it has to be heated, use warm water of 40 (104
) or lower. Do not heat using boiling water.

A If the refrigerant, O-rings, etc. for R12 are used in the R134a air conditioner system, problems such as
refrigerant leakage or cloudiness in the sight glass may occur. Therefore, in order to prevent charging
of refrigerant or erroneous connections, the shapes of the piping joint as well as the shapes of the
service valve and the service tools have been changed.
A Always keep the working place clean and dry and free from dirt and dust. Wipe off water from the line
fittings with a clean cloth before disconnecting.
A Use only for R134a refrigerant service tool.
A Use for R134a refrigerant recovery and recycling machine when discharging the refrigerant.
A Before attaching the charging hose to the can tap valve of the refrigerant container, check each packing
for clogging.
A When disconnecting the charging hose from the charging valve of compressor and receiver, remove it
as quick as possible so that gas leakage can be minimized.
A Be sure to charge the specified amount of refrigerant, but not excessively. Over-charging of the
refrigerant in particular may cause insufficient cooling, etc..
A Since the charging hose can be connected to can tap valve by hand, do not use a pliers for tightening it.
A Keep refrigerant containers in a cool and dark place avoiding such place which are subject to strong
sunlight or high temperature.
A R134a compressor oil absorbs moisture easily, so that be sure to seal after disconnecting the each
parts.
A Do not use old-type refrigerant R12a or compressor oil for old-type refrigerant.
A When replacing the condenser, evaporator and receiver, etc., replenish the compressor oil to
compressor according to the table below.

(2) Refrigerant Charging Hose


The charging hoses are classified into three colors. Each
charging hose must be handled as follows :
A The air conditioner manufacture recommends that the blue
hose (3) is used for the LO pressure side (suction side), the
green hose (5) for refrigeration side (center connecting port)
and the red hose (4) for HI pressure side (discharged side).
(When connecting)
A Push the quick disconnect adaptor (6) into the charging valve,
and push on part A until a click is heard.

A When connecting, push carefully so the pipe doesn't


bend.
A When connecting the quick disconnect connector, should
the sleeve (7) move before the quick link connector can be
connected to the charging valve, move the quick sleeve to
its original position and try again.
A When some refrigerant remains in the charging hose at
the time of connections, it may be difficult to connect the
quick link connector. In this case, perform the operation
after removing any residual pressure in the hose.
(Remove the residual pressure by pushing the pusher
(8).)
(When reassembling)
A While holding on to part A of the quick disconnect adaptor,
slide part B up.

A After removing the adaptor, ensure to cap the quick


disconnect adaptor service valve.

(3) Vacuum Pump Adaptor


Objective of the Vacuum Pump Adaptor
1. After vacuum has been created in the air conditioning cycle,
when the vacuum pump is stopped, since there is vacuum in
hoses within the gauge manifold, the vacuum pump oil flows
back into the charging hose. If the refrigerant is refilled with
the system still in this state, the vacuum pump oil left in the
charging hose enters the air conditioner cycle together with
the refrigerant. Vacuum pump adaptor with a solenoid valve
is used to prevent this back-flow of oil from the vacuum pump.
The role of the solenoid valve is that when the current passes
through the solenoid valve, the valve closes to keep out the
outside air and allow the vacuum to build up, but when the
current stops, the valve opens to allow in air and end the
vacuum.
2. Attaching this adaptor to the R12 vacuum pump currently
being used allows the pump to be used with both R134a and
R12.

(4) Electric Gas Leak Tester


The current R12 gas leak tester has poor sensitivity for R134a
and cannot be used. Therefore, a new electric gas leak tester with
greater sensitivity has been designed and can be used with both
R134a and R12.
(Reference)
Leak tester with halide torch
A Since the reaction with chlorine within the refrigerant is used
to detect gas leaks, R134a, which contains no chlorine, cannot
be detected.

(5) Can Tap Valve


The can tap valve that is used to charge the refrigerant into the
air conditioning system, should be used as follows :
1. Before putting the can tap valve on the refrigerant container,
turn the handle (1) counterclockwise till the valve needle is
fully retracted.
2. Turn the plate nut (disc) (4) counterclockwise till it reaches its
highest position, then screw down the can tap valve into the
sealed tap.
3. Turn the place nut clockwise fully, and fix the center charging
hose to the valve.
4. Tighten the place nut firmly by hand.
5. Turn the handle (1) clockwise, thus making a hole in the
sealed tap.
6. To charge the refrigerant into the system, turn the handle (1)
counterclockwise. To stop charging, turn it clockwise.

(7) R134a Refrigerant Recovery and Recycling Machine


When there is necessity of discharging the refrigerant on
repairing the tractor, it should use recovery and recycling
machine. (Don't release the refrigerant into the atmosphere.)

A Use only R134a refrigerant recovery and recycling


machine, eliminate mixing R134a equipment, refrigerant
and refrigerant oils with R12 systems to prevent
compressor damage.

(3) Charging the System


Charging an Empty System (Liquid)
This procedure is for charging an empty system through the HI
pressure side with the refrigerant in the liquid state.

A Never run the engine when charging the system through


the HI pressure side.
A Do not open the LO pressure valve when refrigerant
R134a is being charged in the liquid state (refrigerant
container is placed upside-down).

A After charging the refrigerant in the liquid state with


approx. 500 g (1.1 lbs) through the HI pressure side, be
sure to recharge the refrigerant in the vapor state to
specified amount through the LO pressure side.
1. Close the HI and LO pressure side valves (6), (5) of manifold
gauge after the system is evacuated completely.
2. Connect the center charging hose (4) to the can tap valve (7)
fitting, and then loosen the center charging hose at the center
fitting of manifold gauge until hiss can be heard.
Allow the air to escape for few seconds and tighten the nut.
3. Open the HI pressure side valve (6) fully, and keep the
container upside-down to charge the refrigerant in the liquid
state from the HI pressure side.
4. Charge the refrigerant in the liquid state with approx. 500 g
(1.1 lbs) from the HI pressure side.

A If LO pressure gauge does not show a reading, the system


is clogged and must be repaired.

Charging an Empty or Partially Charged System (Vapor)


This procedure is to charge the system through the LO
pressure side with refrigerant in the vapor state. When the
refrigerant container is placed right side up, refrigerant will enter
the system as a vapor.

A Never open the HI pressure valve of manifold gauge while


the engine is running.

A Do not turn the refrigerant container upside-down when


charging the system by running the engine.
A Put refrigerant container into a pan of warm water
(maximum temperature 40 (104 )) to keep the vapor
pressure in the container slightly higher than vapor
pressure in the system.
1. Check that the HI pressure valve (4) is closed.
2. Start the engine and set an approx. 1500 (rpm).
3. Turn on the A/C switch.
Set the temperature control lever to maximum cooling
position and the blower switch to HI position.
4. Open the LO pressure valve (3) of manifold gauge and the can
tap valve (5) on refrigerant container and charge the
refrigerant until air bubbles in the sight glass of the receiver
vanish.
5. After charging the specified amount of refrigerant into the
system, close the LO pressure valve (3) of manifold gauge
and can tap valve (5), then stop the engine.
6. Check for gas leak with an electric gas leak tester (see page
10-S13).

(4) Checking Charge Refrigerant Amount


After charging the refrigerant, check for amount of charging
refrigerant as follows.

A The pressure on the following checking are the gauge


indications at ambient temperature 30 (86 ), so it
should be noted that the pressure will differ some what
with the ambient temperature.
1. Disconnect the 1P connector (6) of magnetic clutch.
2. Start the engine and set a approx. 1500 (rpm).
3. Connect the 1P connector (6) of magnetic clutch to battery
directly, and then set the blower switch to HI position.
4. Leave the system for approx. 5 minutes until the refrigerant
cycle becomes stable, keeping pressure on the HI pressure
side from 1.27 to 1.66 MPa (13 to 17 , 185 to 242 psi).
5. When the refrigerant cycle is stabilizer, turn off the blower
switch and let the compressor alone to run. Then pressure on
the LO pressure side gradually drops. At this time, if pressure
on the HI pressure side is maintained from 1.27 to 1.66 MPa
(13 to 17 , 185 to 242 psi), air bubbles which pass
through the sight glass becomes as stated below depending
on refrigerant charged amount.
B Insufficient refrigerant charge
Air bubbles pass continuously the sight glass when pressure on
the LO pressure side is over 99.0 kPa (1.01 , 14.4 psi). In
this case, charge the refrigerant from the LO pressure side.
B Properly refrigerant charge
Air bubbles pass through the sight glass continuously when
pressure on the LO pressure side is within 59 to 98 kPa (0.6 to 1.0
, 9 to 14 psi).
If the charge refrigerant amount is proper, no air bubble is
observed on the sight glass at pressure on the LO pressure side
over 99.0 kPa (1.01 , 14.4 psi) when the blower switch is
turned on. When the blower switch is turned off, bubbles pass
through the sight glass in case pressure on the LO pressure side
is within 59 to 98 kPa (0.6 to 1.0 , 9 to 14 psi).
B Excessive refrigerant charge
Air bubbles pass through the sight glass time to time or no air
bubble is observed when pressure on the LO pressure side is
under 59 kPa (0.6 , 9 psi).
In this case, discharge excessive refrigerant gradually from the
LO pressure side.

1. Connect the manifold gauge (3) to compressor as following
procedure.
Close the HI and LO pressure valves (4), (5) of manifold gauge
tightly, and connect the charging hoses (red and blue) (6), (7)
to the respective compressor service valves. (Refer to
HANDLING OF SERVICE TOOLS : See page 10-S10.)

A Be sure to blow out the air in the charging hoses at the


manifold gauge connection end by utilizing the refrigerant
pressure in the refrigerant cycle.
2. Start the engine and set at approx. 1500 (rpm). Turn on
the A/C switch, then set the blower switch to HI position.
3. Raise pressure on the HI pressure side of the refrigerant cycle
by covering the condenser front with a corrugated carboard,
and the pressure switch (8) is activated and the compressor
magnetic clutch is turned off. At this time, read the HI pressure
gauge of the manifold gauge. If this pressure reading differs
largely with the setting pressure, replace the pressure switch
with a new one.
