PILOT VALVE – HYDRAULIC UNITS
OPERATION
The pilot valve casing contains a vertical shaft hole with a reducing valve incorporated into it. When the handle is tilted, the push rod and spring seat are pushed down changing the secondary pressure springʼs pressure.
The casing provides the inlet port P (the primary pressure) and the tank port T. The secondary pressure commensurate with the variation of the operation angle of the handle (1) is taken out through the output ports A and B below the vertical shaft hole. The secondary pressure functions as the pilot pressure to actuate the spool of the control valve (2).
When the Handle (1) is at the Neutral Position:
The force of the spring (3) for setting the secondary pressure that determines the output pressure of the pilot valve is not conveyed to the spool (4). There- fore, the spool (4) is pushed up by the return spring (5), and the output ports A and B are connected with the tank port T, making the pressures in the ports A and B equal to the pressure in the tank port T.
When the Handle (1) is Tilted:
When the handle (1) is tilted and the push rod (6) is pushed, the spool (4) moves downward and the input port P is connected with the output port A. Then, the oil from the pilot pump flows into the output port A, generating a pressure.
When the Handle (1) is Kept at a Certain Position:
When the pressure in the output port A increases to the level equivalent to the force of the spring (3) set by inclination the handle (1), the hydraulic pressure balances with the spring force. When the pressure in the output port A becomes higher than the set spring force, the output port A and the input port P close while the output port B and the tank port T open. When the pressure in the output port A becomes lower than the set spring force, the output port A and the input port P open while the output port B and the tank port T close. Thus, the secondary pressure is always kept constant.

TRAVEL MOTOR
General Cautions
• Carry out disassembly and assembly in a clean place and place the disassembled parts in a place where they will be kept clean at all times.
• Before disassembly, clean the outside surfaces around the ports thoroughly, using a wire brush to remove paint from the joints.
• Clean all disassembled parts with clean hydraulic oil such as diesel fuel.
• Make match marks, etc. on each of the parts so that they can be assembled in their original positions during assembly.
Disassembly
1. Take out the socket bolts and remove the cover (1 ).
2. Take out the plug (2).
3. Take out the cap (3).
HYDRAULIC UNITS
• Replace all seals each time the travel motor is disassembled, applying a thin coat of grease to the seals before fitting them.
• Check each part to make sure there is no abnormal wear or seizing and use sand paper, etc. to remove burrs and sharp edges, etc.

(2) Diaphragm assy inspection
Inspect the diaphragm assy on the rocker arm cover
every 1000 hours or 2 years, whichever comes first. Refer to 4.2.4 point 6 for the function of the diaphragm.
1)Loosen screws, and remove a diaphragm assy, and check whether oil and so on doesn’t enter between the diaphragm and the cover. If oil and so on enters into the diaphragm assy, the diaphragm doesn’t work well.
2)Check the damages of the diaphragm rubber and the spring. If necessary, replace with new ones.
[NOTICE]
• When a diaphragm is damaged, pressure control inside the crankcase becomes insufficient, and troubles
such as combustion defect and so on occur.
• At lube oil replacement or lube oil supply the amount of lube oil isn’t to be beyond the standard upper limit.
If the lube oil quantity is beyond the upper limit or an engine is operated beyond the allowable maximum angle of an engine, the amount of oil mist may be inducted in the combustion chamber and the oil hammer sometimes may occur.
(3) Intake/exhaust valve clearance adjustment
Make measurement and adjustment while the engine is cold.
(a)Valve clearance measurement
1)Remove the rocker arm cover above cylinder head.
2)Set the No.1 cylinder in the compression TDC
Turn the crankshaft to bring the piston of the No.1 cylinder to its compression top dead center while watching the rocker arm motion, timing scale and the top mark position of the crankshaft pulley.
(Position where both the intake and exhaust valves are closed.)
Notes:
• The crankshaft shall be turned clockwise as seen from the radiator side.
• The No.1 cylinder position is on the opposite side of the radiator.
• Since there is a clearance between the rocker arm and valve at the compression top dead center, the position of TDC can be checked by hand. Also see that the top mark on the crankshaft pulley aligns with the mark on the gear case. If there is no valve clearance, disassemble and inspect around the valve seat, since the valve seat may be worn abnormally.
