Note
l
Sefore disconnecting the hose, make marks at the
connections for proper reinstallation.
2. Disconnect the high-pressure hose from the oil pump. At-
tach the SST.
3.
Bleed air from the system,
4. Open the gauge valve fully. Start the engine and turn the
steering wheel fully left and right to raise the fluid tempera-
ture to 50-60% (122-140OF).
5. Close the gauge valve completely. Increase the engine
speed to l,OOO-1,500 rpm and measure the fluid pres-
sure generated by the oil pump. If the pressure is below
specification, replace the oil pump assembly.
Oil pump fluid pressure:
7,848 kPa (80 kg/cm2, I $137 psi)
Caution
l
If the valve is left closed for more than 15 seconds,
the fluid temperature will increase excessively and
adversely affect the oil pump.
6. Open the gauge valve fully again and increase the engine
speed to l,OOO-1,500 rpm.
7. Turn the steering wheel fully to the left and right and meas-
ure the fluid pressure generated by the gear housing. If the
pressure is below specification, replace the gear housing
assembly .
Gear housing fluid pressure:
7,848 kPa (80 kg/cm2, 1,137 psi)
Caution
l
If the steering wheel is kept in the fully turned po-
sition for more than 15 seconds, the fluid tempera-
ture will rise excessively.
8. Remove the gauge set. Install and tighten the high-pressure
hose to the specified torque.
Tightening torque:
16-24 N-m (I .6-2.4 m-kg, 12-17 f&lb)
9. Bleed air from the system.
