INSPECT OIL PUMP
Check the tip clearance.
Using a feeler gauge, measure the clearance between the drive and driven rotor tips.
| Standard clearance |
|---|
| 0.06 to 0.16 mm (0.00236 to 0.00630 in.) |
| Maximum clearance |
|---|
| 0.21 mm (0.00827 in.) |
If the tip clearance is more than the maximum, replace the timing gear case assembly.
Check the body clearance.
Using a feeler gauge, measure the clearance between the oil pump body and driven rotor.
| Standard clearance |
|---|
| 0.10 to 0.17 mm (0.00394 to 0.00669 in.) |
| Maximum clearance |
|---|
| 0.2 mm (0.00787 in.) |
If the body clearance is more than the maximum, replace the timing gear case assembly.
Check the side clearance.
Using a feeler gauge and precision straightedge, measure the clearance between the rotor and precision straightedge.
| Standard clearance |
|---|
| 0.03 to 0.09 mm (0.00118 to 0.00354 in.) |
| Maximum clearance |
|---|
| 0.15 mm (0.00591 in.) |
If the side clearance is more than the maximum, replace the timing gear case assembly.
