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.

(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.

2. COOLING SYSTEM
(1) Radiator
(2) Cooling Fan
(3) Thermostat
(4) Water Pump
(5) Cylinder Head Water
Jacket
(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.

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.

With the shuttle lever at F or R position, when the clutch pedal is depressed, the spool 2 (9) is moved to the left.
And pressure difference between a part and b part is generated. As the spool 1 (2) is moved to the left by pressure
difference, F port (or R port) and T1 port are connected.
The oil in the shuttle clutch returns into the transmission case via F port (or R port), notched portion of spool 1 (2)
and T1 port. This cause the shuttle clutch to be set to off.
At the same time, as the hole c and passage d are connected, oil passage among the hole e, hole c and T1 port
are connected. As a result, even when the spool 1 (2) does not move, the oil passage from F port (or R side) to T1
port is secured..

5. OIL FILTER
Two oil filter are located in parallel at the pump
suction line. A permanent magnet, servicing as a
magnet filter, is inserted in the paper type element of
each cartridge, which ensures a filtration degree of b60
or BETA60 = 2.5 (MIN)*
* This is authorized by ISO / 4572 Filter Element Multi
Pass Test.

6. POWER STEERING
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.

[1] POSITION CONTROL
Position control is a linkage mechanism to raise or lower the implement attached to the tractor in proportion to the
movement of the position control lever.
The implement can be positioned at any height by moving the position control lever. Fine position adjustment is
also easy.

(2) Lever Shaft (6) Torsion Bar (10) Link 1 (13) Fixed Arm
(3) Feedback Shaft (7) Top Link (11) Spring (14) Control Valve
(4) Feedback Rod (8) Link 2
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).
0000001721E
When the traction load increases, the torsion bar (6) is twisted, and its displacement is transmitted to the feedback
shaft (3) via the feedback rod (4). The feedback shaft (3) rotates clockwise and push the link 1 (10) to rotate the link
2 (8) clockwise.
The link 2 (8) pushes the spool (12) in via the spool drive lever (9) and the "LIFT" circuit is formed.
As the implement is raised and the traction load decreases, the torsion bar (6) is restored to return the spool (12) to
neutral.
0000001722E
When the traction load decreases, the torsion bar (6) is restored and its displacement is transmitted to the feedback
shaft (3) via the feedback rod (4). As the feedback shaft (3) rotates counterclockwise, the spool drive lever (9) pulls
the spool (12) out by the spring (11) to form the "DOWN" circuit.
As the implement lowers and the traction load increases, the torsion bar (6) is twisted to return the spool (12) to
neutral.

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.

(1) Checking
Battery Voltage
1. Stop the engine and turn the main switch off.
2. Connect the COM (-) lead of the voltmeter to the battery's
negative terminal post and the (+) lead to the positive terminal
post, and measure the battery voltage.
3. If the battery voltage is less than the factory specification,
check the battery specific gravity and recharge the battery.
Battery voltage Factory spec. More than 12 V
0000001140E
0000001141E
(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 )

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.
