Symptom Chart
Listed below are symptoms and probable causes for problems that DO NOT cause the malfunction Indicator Lamp (MlL) to
come on. lf the MIL was reported on, go to page 11-32.
Troubleshooting each probable cause in the order listed (from left to right) until the symptom is eliminated.
The probable cause and troubleshooting page relerence can be found below.

Inspection and Adjustment
Pump Pressure Check
Check the fluid Dressure 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.
CAUTION: Disconnect the pump outlet hose (high-pres-
sure line) with care so as not to spill the power steering
fluid on the frame and other parts,
1. Disconnect the pump outlet hose (high-pressure)
from the pump outlet fitting, then install the P/S
joint adapter (pump) on the pump outlet.

PUMPFITTING
Connect the P/S joint adapter (hose) to the power
steering pressure gauge, then connect the pump
outlet hose (high-pressure)to the adapter.
Install the power steering pressure gauge to the P/S
joint adapter (pump).
Open the shut-off valve fully.
Open the pressure control valve fulli.
1.
Start the engine and let it idle.
Turn the steering wheel from lock-to-lock several
times to warm the fluid to operating temperature.
Measure steady-state fluid pressure while idling. lf
the pump is in good condition, the gauge should
read less than 1500 kPa (15 kgflcm' ,213 psi).
lf it reads high, check the outlet hose or valve body
unit (see General Troubleshooting 17-101.
Close the pressure control valve, then close the
shut-off valve gradually until the pressure gauge
needle is stable, Read the pressure.
lmmediately open the pressure control valve fully.
CAUTION: Do not keep the pressure control valve
closed more then 5 seconds or the pump could be
damaged by over-heating.
lf the pump is in good condition, the gauge should
read at least 6,400 - 7,400 kPa (65 - 75 kgflcm',924- 1,067 psi). A low.eading means pump output is
too low for full assist. Repair or replace the pump.

Rear Bearing ReplacementAlternator Reassembly
MITSUBISHI:
1. Pull off the rear bearing.
Make sure the tips of the bearing puller jaws are
thin enough to fit between the bearing and the
slip rings.
Do not reuse the bearing.
BEARING PULITRSLIPRINGS (Commorciallyav6ilable)
Use a hand press to install the new bearing. Applypressure only on the inner race to avoid damaging
the bearing.

REAR BEARING
1.Push the brushes in, then insert a pin or drill bit(about 1.8 mm diameter)to hold them there.
ARUSHES
Heat the rear bearing seat in the rear housing as
described on page 23-12. After heating, continue
immediately with assembling before the rear bear-ing seat cools completely.
Put the rear housing/stator assembly and drive-end
housing/rotor assembly together, tighten the four
through bolts and pull out the pin.
