PROCEDURE
INSPECT OIL PUMP DRIVE AND DRIVEN ROTORS
| *a | Feeler Gauge |
Check the tip clearance.
Using a feeler gauge, measure the clearance between the tips of the oil pump drive rotor and oil pump driven rotor.
| Standard Tip Clearance |
|---|
| 0.08 to 0.16 mm (0.00315 to 0.00630 in.) |
| Maximum Tip Clearance |
|---|
| 0.21 mm (0.00827 in.) |
If the tip clearance is more than the maximum, replace the oil pump rotor set.
| *a | Feeler Gauge |
Check the body clearance.
Using a feeler gauge, measure the clearance between the oil pump driven rotor and oil pan sub-assembly.
| Standard Body Clearance |
|---|
| 0.10 to 0.18 mm (0.00394 to 0.00709 in.) |
| Maximum Body Clearance |
|---|
| 0.20 mm (0.00787 in.) |
If the body clearance is more than the maximum, replace the oil pump rotor set or oil pan sub-assembly.
| *a | Feeler Gauge |
| *b | Steel Square |
Check the side clearance.
Using a feeler gauge and steel square, measure the clearance between the oil pump rotor set and steel square.
| Standard Side Clearance |
|---|
| 0.03 to 0.09 mm (0.00118 to 0.00354 in.) |
| Maximum Side Clearance |
|---|
| 0.15 mm (0.00591 in.) |
If the side clearance is more than the maximum, replace the oil pump rotor set or oil pan sub-assembly.
