INSPECTION
PROCEDURE
1. INSPECT OIL PUMP RELIEF VALVE
| (a) Coat the oil pump relief valve with engine oil, then check that it falls smoothly into the valve hole by its own weight. HINT: If the oil pump relief valve does not fall smoothly, replace the oil pump assembly. |
|
2. INSPECT OIL PUMP ROTOR
(a) Check the side clearance (Oil pump driven rotor side).
| (1) Using a vernier caliper, measure the width of the oil pump driven rotor. HINT: Perform the measurement at 3 random places. |
|
(2) Using a vernier caliper and precision straightedge, measure the depth of the oil pump body.
NOTICE:
Make sure to deduct the thickness of the precision straightedge.
HINT:
Perform the measurement at 3 random places.
(3) Subtract the oil pump driven rotor width measurement from the oil pump body depth measurement.
Standard Side Clearance:
0.025 to 0.070 mm (0.000984 to 0.00276 in.)
HINT:
If the result is not as specified, replace the oil pump assembly.
(b) Check the side clearance (Oil pump regulator ring side).
| (1) Using a vernier caliper, measure the width of the oil pump regulator ring. HINT: Perform the measurement at 3 random places. |
|
(2) Using a vernier caliper and precision straightedge, measure the depth of the oil pump body.
NOTICE:
Make sure to deduct the thickness of the precision straightedge.
HINT:
Perform the measurement at 3 random places.
(3) Subtract the oil pump regulator ring width measurement from the oil pump body depth measurement.
Standard Side Clearance:
0.025 to 0.075 mm (0.000984 to 0.00295 in.)
HINT:
If the result is not as specified, replace the oil pump assembly.
