INSPECTION AFTER DISASSEMBLY

Oil Pump Clearance





- Measure the clearance with feeler gauge.
- Clearance between outer rotor and front cover (Position "1")
Standard: Oil Pump.
- Tip clearance between inner rotor and outer rotor (Position "2")
Standard: Oil Pump.





- Measure the clearance with feeler gauge and straightedge.
- Side clearance between inner rotor and front cover (Position "3")
Standard: Oil Pump.
- Side clearance between outer rotor and front cover (Position "4")
Standard: Oil Pump.
- Calculate the clearance between oil pump inner rotor and oil pump body as follows:





- Measure the outer diameter of protruded portion of inner rotor with micrometer. (Position "5")





- Measure the inner diameter of front cover with in side micrometer.
(Position "6")
- (Clearance) = (Front cover inner diameter) - (Oil pump inner rotor outer diameter)
Standard: Oil Pump.
- If measured/calculated values are out of the standard, replace front cover.
Regulator Valve Clearance (Clearance) = (Regulator valve hole diameter) - (Regulator valve outer diameter)





Standard: Regulator Valve.
- If the calculated value is out of the standard, replace front cover.

CAUTION:
- Coat regulator valve with engine oil.
- Check that it falls smoothly into valve hole by its own weight.

INSPECTION AFTER INSTALLATION

1.Check the engine oil level. Inspection.
2.Start the engine, and check that there is no leakage of engine oil.
3.Stop the engine and wait for 10 minutes.
4.Check the engine oil level and adjust the level. Inspection.
