INSPECTION AFTER DISASSEMBLY

Clearance of Oil Pump Parts





- Measure radial clearance using a suitable tool.


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






- Measure side clearance using suitable tools.


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






- 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 to oil pump cover : Refer to "Regulator Valve". Regulator Valve

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. 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. Inspection.
