OIL PUMP - INSPECTION
| 1. INSPECT OIL PUMP RELIEF VALVE |
Coat the relief valve with engine oil.
Check that the relief valve falls smoothly into the valve hole by its own weight.
If the relief valve does not, replace it. If necessary, replace the oil pump cover assembly.
| 2. INSPECT OIL PUMP ROTOR SET |
Install the rotors to the oil pump cover assembly. Check that the rotors revolve smoothly.
Check the tip clearance.
Using a feeler gauge, measure the clearance between the drive and driven rotor tips, as shown in the illustration.
- Standard Tip Clearance:
- 0.10 to 0.22 mm (0.00394 to 0.00866 in.)
- Maximum Tip Clearance:
- 0.22 mm (0.00866 in.)
If the tip clearance is more than the maximum, replace the oil pump cover assembly.
Check the body clearance.
Using a feeler gauge, measure the clearance between the timing chain cover and driven rotor, as shown in the illustration.
- Standard Body Clearance:
- 0.075 to 0.170 mm (0.00296 to 0.00669 in.)
- Maximum Body Clearance:
- 0.170 mm (0.00669 in.)
If the body clearance is more than the maximum, replace the oil pump cover assembly.
