INSPECT RELIEF VALVE
Coat the valve with engine oil and check that it falls
smoothly into the valve hole by its own weight,
If it does not, replace the relief valve.,If necessary, replace
the oil pump assembly.
INSPECT BODY CLEARANCE
Using a thickness gauge, measure the clearance between
the driven gear and pump body.
Standard clearance:
0.105 - 0.175 mm
(0.0041 - 0.0069 in.1
Maximum clearance: 0.2 mm (0.008 in.)
If the clearance is greater than maximum, replace the gear
or oil pump assembly.
INSPECT GEAR BACKLASH
Using a thickness gauge, measure the backlash as shown
in several places.
Standard backlash: 0.5 - 0.6 mm
(0.020 - 0.024 in.)
Maximum backlash: 0.9 mm (0.035 in.)
If the backlash is greater than maximum, replace the oil
pump drive shaft and driven gear.
INSPECT SIDE CLEARANCE
Using a thickness gauge and precision straight edge,
measure the clearance between the gears and precision
straight edge.
Standard clearance:
0.03 - 0.09 mm
(0.0012 - 0.0035 in.)
Maximum clearance: 0.15 mm (0.0059 in.)
If the clearance is greater than maximum, replace the drive
shaft and driven gear. If necessary, the oil pump assembly.
