INSPECTION AFTER DISASSEMBLY

Clearance of Oil Pump Parts





- Measure radial clearance using a suitable tool.
Body to outer rotor : Refer to "Oil Pump" Oil Pump.


(position 1)
Inner rotor to outer : Refer to "Oil Pump" Oil Pump.
rotor tip (position 2)





- Measure side clearance using suitable tools.
Body to inner rotor : Refer to "Oil Pump" Oil Pump.


(position 3)
Body to outer rotor : Refer to "Oil Pump" Oil Pump.
(position 4)





- Calculate the clearance between inner rotor and oil pump body as follows.
1.Measure the outer diameter of protruded portion of inner rotor (position 5) using suitable tool.





2.Measure the inner diameter of oil pump body to brazed portion (position 6) using suitable tool.
3.Calculate the clearance using the following formula.
- (Clearance) = (Inner diameter of oil pump body) - (Outer diameter of inner rotor)
Inner rotor to brazed portion of housing clearance: Refer to "Oil Pump" Oil Pump.
Regulator Valve Clearance
Check regulator valve to oil pump cover clearance using the following formula.





- (Clearance) = D1 (Valve hole diameter) - D2 (Outer Diameter of valve)
Regulator valve : Refer to "Regulator Valve" Regulator Valve.


to oil pump cover

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

INSPECTION AFTER INSTALLATION

1.Check the engine oil level. Refer to "Inspection" Inspection
2.Start the engine and check for engine oil leaks.
3.Stop the engine and wait 10 minutes.
4.Check the engine oil level and adjust the engine oil level as required. Refer to "Inspection" Inspection.
