z Inspection and correction
1) With steel rule and feeler gauge,
measure the axial end play of the
oil pump gear. Replace if the
measured value is beyond the limit.
End play limit 0.03 ∼ 0.136 mm
2) With a feeler gauge, measure the
amount of backlash between the
oil pump drive gear and driven
gear. Replace if the measured
value is beyond the limit.
Standard 0.312 ~ 0.476 mm
Limit 0.64 mm
3) Measuring clearance between drive shaft and bushing
a. Measure the outside diameters of the drive shaft and driven shaft, and
replace if the measured values are less than the limit.
Standard φ21.936 ∼ φ21.95
Limit φ21.90 mm
b. Measure the inside diameter of the pump body bushing to determine the
clearance between the bushing and shaft, and compare the measured
value with the standard value to determine whether to replace or no.
Oil clearance 0.050 ~ 0.085 mm
z Reassembly
(1) For reassembly, reverse the disassembly sequence.
