INSPECTION AFTER DISASSEMBLY
Oil Pump Clearance
• Measure the clearance with feeler gauge (C).
- Clearance between oil pump outer rotor and oil pump body [posi-
tion (B)]
- Tip clearance between oil pump inner rotor and oil pump outer
rotor [position (A)]
• Measure the clearance with feeler gauge and straightedge (A).
- Side clearance between oil pump inner rotor and oil pump body
[position (C)]
- Side clearance between oil pump outer rotor and oil pump body
[position (B)]
• Calculate the clearance between oil pump inner rotor and oil pump body as follows:
OIL PUMP BODY INNER DIAMETER
- Measure the inner diameter of oil pump body with inside microme-
ter. [position (A)]
OIL PUMP INNER ROTOR OUTER DIAMETER
- Measure the outer diameter of protruded portion of oil pump inner
rotor (1) with micrometer. [position (B)]
OIL PUMP INNER ROTOR TO OIL PUMP BODY CLEARANCE
- (Clearance) = (Oil pump body inner diameter) – (Oil pump inner rotor outer diameter)

• If measured/calculated values are out of the standard, replace oil pump assembly.
Regulator Valve Clearance
(Clearance) = (Regulator valve hole diameter) – (Regulator valve
outer diameter)
• If the calculated value is out of the standard, replace oil pump
assembly.
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. Refer to
.
2.
Start the engine, and check 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
