PROCEDURE
INSPECT OIL PUMP
| *1 | Mark |
Install the drive rotor and driven rotor to the timing chain cover sub-assembly with the marks of the rotor facing the cylinder block sub-assembly side. Check that the rotors revolve smoothly.
Check the tip clearance.
Using a feeler gauge, measure the clearance between the drive rotor and driven rotor tips.
| Standard tip clearance |
|---|
| 0.180 to 0.300 mm (0.00709 to 0.0118 in.) |
| Maximum tip clearance |
|---|
| 0.300 mm (0.0118 in.) |
If the tip clearance is more than the maximum, replace the timing chain cover sub-assembly.
Check the body clearance.
Using a feeler gauge, measure the clearance between the oil pump body and driven rotor.
| Standard body clearance |
|---|
| 0.175 to 0.250 mm (0.00689 to 0.00984 in.) |
| Maximum body clearance |
|---|
| 0.250 mm (0.00984 in.) |
If the body clearance is more than the maximum, replace the timing chain cover sub-assembly.
Check the side clearance.
Using a feeler gauge and precision straightedge, measure the clearance between the rotors and precision straightedge.
| Standard side clearance |
|---|
| 0.030 to 0.090 mm (0.00118 to 0.00354 in.) |
| Maximum side clearance |
|---|
| 0.090 mm (0.00354 in.) |
If the side clearance is more than the maximum, replace the timing chain cover sub-assembly.
