Inspection
Inspect oil pump shaft assembly, housing and cov-
er for marks or other damages.
Check inner rotor for corrosion, pin-holes or other
damages. If so, replace oil pump shaft assembly.
Ensure to also check oil pump housing and cover
and replace if damaged.
1. Pittings on the teeth
Using a feeler gauge, measure the clearance be-
tween inner and outer rotors.
1. Outer rotor
2. Inner rotor
If clearance between inner and outer rotors ex-
ceeds the tolerance, replace oil pump shaft as-
sembly. Ensure to also check oil pump housing
and cover and replace if damaged.
If clearance between outer rotor and its bore in oil
pump exceeds the tolerance, replace the com-
plete oil pump and the PTO housing.
Using a vernier depth gage, measure side wear as
shown.
1. Oil pump housing surface
2. Vernier depth gage
1. Oil pump outer rotor surface
2. Vernier depth gage
Difference between pump housing and outer rotor
should not exceed 0.1 mm (.004 in). If so, replace
the complete oil pump assembly.
NOTE: When the axial clearance of the oil pump
shaft assembly increases, the oil pressure de-
creases.
Check the inside of oil pump housing and its cover
for scoring or other damages and replace if dam-
aged.
