POWER STEERING OIL PUMP
1.
Connect the oil pressure gauge [SST: KV48103500 (J-26357)]
and the oil pressure gauge adapter [SST: KV48102500 (J-
33914)] between oil pump discharge connector and high-pres-
sure hose. Bleed air from the hydraulic circuit while opening
valve fully. Refer to
.
2.
Start engine. Run engine until oil temperature reaches 50 to
80
°
C (122 to 176
°
F).
CAUTION:
• Leave the valve of the oil pressure gauge fully open while
starting and running engine. If engine is started with the
valve closed, the hydraulic pressure in oil pump goes up
to the relief pressure along with unusual increase of oil
temperature.
• Be sure to keep hose clear of belts and other parts when
engine is started.
3.
Fully close the oil pressure gauge valve with engine at idle and
measure the relief oil pressure.
CAUTION:
Never keep valve closed for 10 seconds or longer.
4.
Open the valve slowly after measuring. Repair oil pump if the relief oil pressure is outside the standard.
Refer to
ST-51, "WITH 4WAS : Disassembly and Assembly"
5.
Disconnect the oil pressure gauge from hydraulic circuit.
6.
When installing eye bolt (1) and copper washer (2) to oil pump
(3), refer to the figure.
CAUTION:
• Never reuse copper washer.
• Apply power steering fluid or equivalent to around copper
washer, then install eye-bolt.
• Install eye-bolt with eye-joint (assembled to high pressure
hose) (B) protrusion (A) facing with pump side cutout, and
then tighten it to the specified torque after tightening by
hand. Refer to
(2WD mod-
els),
(AWD models).
• Securely insert harness connector to pressure sensor.
7.
Check fluid level, fluid leakage and air bleeding hydraulic system after the installation. Refer to
BEFORE DISASSEMBLY
Disassemble oil pump only when the following malfunctions occur.
• If oil leakage is found on oil pump.
• Oil pump pulley is damaged or deformed.
• Performance of oil pump is low.
AFTER DISASSEMBLY
Body Assembly and Rear Cover Inspection
• Check body assembly and rear cover for internal damage. Replace rear cover if it is damaged. Replace oil
pump assembly if body assembly is damaged.
Cartridge Assembly Inspection
• Check cam ring, rotor and vane for damage. Replace cartridge assembly if there are.
Side Plate Inspection
• Check side plate for damage. Replace side plate if there are.
Flow Control Valve Inspection
• Check flow control valve and spring for damage. Replace if there are.
