Troubleshooting
Fluid Leaks
Check the gearbox assembly for oil leaks carefully. Oil can leak out of various points. depending on location of thefaulty oil seals/seal rings. Check the following before removing the gearbox from the frame.

lnspection and Adjustment
Pump Pressure Check
Check the fluid pressure as follows to determine
whether the trouble is in the pump or gearbox.
NOTE: First check the power steering fluid level and
pump belt tension,
CAUnON: Dilconn€st the high pros3uro ho3s with cale

1. Disconnect the outlet hose from the oumo outlet fit-
ting, 8nd install the pump joint adapter on the
pump outlet.
2, Connect the hose joint sdapter to the power steer-
ing pressure gauge, then connect the outlet hose to
the adaotor.
3. Instsll the power steering pressure gauge to the
pump joint adaptor as shown.

1.
Start the engine and let it idle.
Turn the stee.ing wheel from lock-to-lock several
times to warm the fluid to operating temperature.
Measure steady-state fluid pressure while idling
with the shut-off valve fully open. lf the pump is in
good condition, the gauge should read less than
1500 kpa (15 kgf/cm,,213 psi).
lf it reads high, check the feed line or valve body
unit (see General Troubleshooting l7-10).
Close the shut-off valve. then close the pressure
control valve gradually until the pressure gauge
needle is stabl6, Read the pressure.
lmmediately open the shut-off valve fully.
CAUTION: Do not keep the shut-ott valvs closod
moro thgn 5 soconds or th9 pump could b6 dam"
agod by over-h6ating,
lf the pump is in good condition, the gauge should
read at least 6.400 - 7,400 kpa (65 - 75 kgIlcm,,924- 1,067 psi). A low reading means pump output is
too low for full assist. Repair or replace the pump.
