STEERING ±
On-vehicle Service
37A-10
8.
If the level changes more than 5 mm, the air is badly bled.
So, bleed air again.
Caution
(1) If the fluid level rises suddenly after the engine
is stopped, the bleeding is incomplete.
(2) Incomplete bleeding causes abnormal noises from
the pump and the flow-control valve. This could
lessen the life of the pump and the other parts.
OIL PUMP PRESSURE TEST
1.
Disconnect the pressure hose from the oil pump, and then
connect the special tools.
2.
Bleed air. Without the vehicle moving, turn the steering
wheel several times to raise the fluid temperature to 50
to 60
_
C.
3.
Start the engine and idle at 1,000
±
100 r/min.
4.
Fully close the shut-off valve of the pressure gauge and
measure the oil pump relief pressure.
Standard value: 8.3 ± 9.0 MPa
5.
If the standard value is not met, disassemble and assemble
the oil pump again. Then, remeasure oil pressure.
6.
With the pressure gauge shut±off valve fully open, check
the hydraulic pressure in unladen condition.
Standard value: 0.2 ± 0.7 MPa
7.
If the standard value is not met, the oil line or steering
gear is probably defective. So, repair and measure oil
pressure again.
8.
Turn the steering wheel fully either left or right and check
the retention hydraulic pressure.
Standard value: 8.3 ± 9.0 MPa
9.
If the pressure is below the standard value, disassemble
and reassemble the steering gear. If above, disassemble
and reassemble the components of the oil pump flow
control valve. Then, measure oil pressure again.
10. Remove the special tools, and tighten the pressure hose
to the specified torque.
Tightening torque: 57 Nm
11. Bleed the system.
Fluid level change: Within 5 mm
