OIL PUMP

INSPECTION AFTER DISASSEMBLY
Clearance of Oil Pump Parts

●

Measure the clearance with feeler gauge.

–

Clearance between outer rotor and oil pump body (position 1)

–

Tip clearance between inner rotor and outer rotor (position 2)

●

Measure the clearance with feeler gauge and straightedge.

–

Side clearance between inner rotor and oil pump body (position
3)

–

Side clearance between outer rotor and oil pump body (position
4)

●

Calculate the clearance between inner rotor and oil pump body
as follows:

–

Measure the inner diameter of oil pump body with inside
micrometer (Position 5)

–

Measure the outer diameter of protruded portion of inner rotor
with micrometer (Position 6)

–

(Clearance) = (Inner diameter of oil pump body) – (Outer diame-
ter of inner rotor)

●

If measured/calculated values are out of the standard, replace
oil pump assembly.

Regulator Valve Clearance

(Clearance) = (Valve hole diameter) – (Regulator valve outer diame-
ter)

●

If out of the standard, replace oil pump assembly.

CAUTION:

●

Coat regulator valve with engine oil.

●

Make sure that it falls smoothly into valve hole by its own
weight.
