2-2. Measuremment and adjustment of propulsion charge circuit pressure
1. Measurement
・
Hydraulic oil temperature: 50±5 °C
Position the machine on level ground.
Stop the engine and chock the wheels.
★ Because oil is supplied from the
steering/charge pump, make sure, prior to
measurement, that the steering system
works correctly.
★ Ensure that the pump swashplate is in the
exact neutral position with the F-R lever
placed in the neutral position.
1) Remove plugs from servo pressure gauge
points (1) and (2) of the propulsion pump.
Attach a pressure gauge with adapter
w
.
・
Servo pressure gauge port: 9/16-18UNF-2B
・
Pressure gauge: 0-4.9 MPa (0-50 kgf/cm
2
)
2) Start the engine and set the throttle lever to
the high idle position.
3) Make sure that the F-R lever is in the
neutral position. Take the gauge reading.
2. Adjustment
If the measured value falls outside the
permissible range, disassemble and wash clean
or renew the pressure relief valve assembly.
★
The valve is of a non-serviceable item. Do
not attempt to adjust it.
Carefully perform disassembly and
reassembly to prevent engress of dirt or
other contaminations.
