Inspection and Adjustment
2-6. Measurement and adjustment of steering circuit pressure
1. Measurement
・
Hydraulic oil temperature: 50±5 °C
Position the machine on level ground.
Stop the engine. Chock the wheels.
★
Because the return line of the steering cir-
cuit makes the pressure source of the
propulsion charge circuit, ensure before
measurement, that the steering system
operates correctly.
1) Disconnect hose (1) at the outlet port of the
steering pump, and fit adapter
u
. Then
reconnect the hose.
2) Install a 0-24.5 MPa (0-250 kgf/cm
2
) pres-
sure gauge to adapter
u
.
3) Start the engine. Ensuring that the F-R
lever is in the neutral position, operate the
throttle lever to select the high idle position.
4) Rotate the steering wheel clockwise or
counterclockwise to full lock in order to
allow the pressure relief valve to release
the pressure. Take the gauge reading.
*
When rotating the steering wheel, do not
allow anyone to enter the pinch area of the
articulated frame.
2. Adjustment
If the measured value is not within the permis-
sible range, disassemble and clean or renew
the relief valve assembly built in Orbitrol.
★
The valve is not adjustable. Do not attempt
to adjust it.
Carefully perform disassembly and
reassembly taking necessary means to
avoid entry of foreign matter.
