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.

Disassembly
CAUTION: The power steering components are made of aluminum. Avoid damaging the componenk during assembly.
NOTE:
. Clean the disassembled parts with a solvent, and dry them with compressed air. Do not dip the rubber parts in a sol-
vent.
. Always replace the O-rings and rubber seals with new ones before assembly.
. Apply recommended power steering fluid to the parts indicated in the assembly procedures.
. Do not allow dust, dirt, or other foreign materials to enter the power steering system.
. Replace the pump as an assembly if the parts indicated with asterisk (*l areworn ordamaged'

Flow Control Valv€:
1. Check the flow control valve for wear. burrs, and
other damage to the edges of the grooves in the
valve.
FLOWCONTROL VALVE
Inspect the bore the flow control valve for scrstches
or wear,
Slip the valve back in the pump, and check that it
moves in and out smoothly.
lf OK, go on step 4; if not, replace the pump as an
assembly. The flow control valve is not available
separately.
Attach a hose to the end of the valve as shown.

5. Submerge the valve in a container of power steer-
ing fluid or solvent, and blow in the hose. lf air bub-
bles leak through the valve at less than 98 kPa
(1.0 kgf/cm', 14.2 psi), replace the pump as an
assembly.
f. AIR PRESSURE
lf the flow control valve tests OK, reinstall it in the
pump. lf the flow control valve still leaks air, replace
the pump as an assembly. The flow control valve is
not available seDaratelv.
