2-3. Measurement of propulsion motor speed selecting pressure
1. Measurement
・
Hydraulic oil temperature: 50
±
5 °C
Position the machine on level surface.
Stop the engine and place chock blocks
in front and rear of wheels.
★
Prior to measurement, check that the
steering system works correctly, since oil
is fed from the steering/charge pump.
1) Disconnect hose (1) in the speed selecting
line from the propulsion motor. Attach a
pressure gauge with adapter
e.
・
Pressure gauge: 0-4.9 MPa (0-50 kgf/cm
2
)
★
These procedures should not apply to the
rear motors.
2) Start the engine and set the throttle lever to
the high idle position.
3) Set the speed selector switch to the High
speed range and take the gauge reading.
