INSPECTION AFTER DISASSEMBLY






- Measure the clearance with feeler gauge (A).
- Clearance between outer rotor and front cover (C)
Standard: Refer to "Oil Pump" Oil Pump.
- Tip clearance between inner rotor and outer rotor (B)
Standard: Refer to "Oil Pump" Oil Pump.





- Measure the clearance with feeler gauge (A) and straightedge (B).
- Side clearance between inner rotor (3) and front cover (1)
Standard: Refer to "Oil Pump" Oil Pump.
- Side clearance between outer rotor (2) and front cover (1)
Standard: Refer to "Oil Pump" 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 (1)
with micrometer (A).





- Measure the inner diameter of inner rotor (1) with inside micrometer (A).
- (Clearance) = (Inner rotor inner diameter) - (Oil pump inner rotor outer diameter)
Standard: Refer to "Oil Pump" Oil Pump.
- If measured/calculated values are out of the standard, replace front cover and oil pump assembly.





- (Clearance) = (Regulator valve hole (1) diameter) - (Regulator valve (2) outer diameter)
Standard: Refer to "Oil Pump" Oil Pump.
- If the calculated value is out of the standard, replace front cover and oil pump assembly.

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

INSPECTION AFTER INSTALLATION

1.Check the engine oil level. Refer to "Inspection" Procedures.
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. Refer to "Inspection" Procedures.
