Inspection & Adjustment
2. Inspection & Adjustment
2-1. Measurement and adjustment of pressure in propulsion main
circuit
Park on level ground. Apply the parking
brake. Stop the engine and block the
wheels.
Make certain that the parking brake func-
tions correctly.
★ Ensure that the propulsion charge circuit
pressure is as specified.
1. Measurement
★
Hydraulic oil temperature: 50±5°C (122±41°F)
1-1. Cut off valve
1
)
Mount a pressure gauge to the couplings
fitted in gauge ports (1) and (2) of the
propulsion pump.
• Port (1): for forward travel
• Port (2): for reverse travel
• Pressure gauge:
0 ~ 60 MPa (0 ~ 600 kgf/cm 2 )
{0 ~ 9000 psi}
2) Apply the parking brake by operating the
parking brake switch.
3) Start the engine and set the throttle to high
idle.
4) Move the F-R lever so that the pressure in
the port to be measured may build up. Take
the pressure reading quickly. Immediately
when the measurement has been taken,
bring the lever to the neutral position.
1-2. High pressure relief valve
1
)
The gauge mounting procedure is the
same as that in step 1-1-1) above.
2 ) Screw in adjust screw (5) of cut off valve
(3) one full turn. Block the cut off valve.
★ For the adjustment screw, see Fig.
SW8003013.
