RELIEF OIL PRESSURE
CAUTION:
Make sure that belt tension is normal before starting the following procedure.
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 the engine. Run the 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 the 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-59, "Disassembly and Assembly"
5.
Disconnect the oil pressure gauge from hydraulic circuit.

When installing eye bolt (1) and copper washers (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
• Securely insert harness connector to pressure sensor.
7.
Check fluid level, fluid leakage and air bleeding hydraulic sys-
tem 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 necessary.
Side Plate Inspection
• Check side plate for damage. Replace side plate if necessary.
Flow Control Valve Inspection
• Check flow control valve and spring for damage. Replace if necessary.
