Oil Pump -- Inspection |
| 1. INSPECT OIL PUMP ASSEMBLY |
Turn the drive gear with 2 screwdrivers and make sure that it rotates smoothly.
- NOTICE:
- Be careful not to damage the oil seal lip.
 |
| 2. INSPECT CLEARANCE OF OIL PUMP ASSEMBLY |
Push the driven gear to one side of the body.
 |
Using a feeler gauge, measure the clearance.
- Standard body clearance:
- 0.10 to 0.17 mm (0.00394 to 0.00669 in.)
- Side clearance:
- 0.02 to 0.05 mm (0.000787 to 0.00197 in.)
- Maximum body clearance:
- 0.17 mm (0.00669 in.)
Using a feeler gauge, measure the tip clearance between the driven gear teeth and drive gear teeth.
- Standard tip clearance:
- 0.07 to 0.15 mm (0.00276 to 0.00591 in.)
- Maximum tip clearance:
- 0.15 mm (0.00591 in.)
 |
Using a straightedge and feeler gauge, measure the side clearance of both gears.
- Standard side clearance:
- 0.02 to 0.05 mm (0.000787 to 0.00197 in.)
- Maximum side clearance:
- 0.05 mm (0.00197 in.)

| 3. INSPECT FRONT OIL PUMP AND GEAR BODY SUB-ASSEMBLY |
Using a dial indicator, measure the inside diameter of the oil pump body bushing.
- Standard inside diameter:
- 38.113 to 38.138 mm (1.50051 to 1.50149 in.)
- Maximum inside diameter:
- 38.188 mm (1.50346 in.)
 |
| 4. INSPECT STATOR SHAFT ASSEMBLY |
Using a dial indicator, measure the inside diameter of the stator shaft.
- Standard inside diameter:
- 21.500 to 21.526 mm (0.84646 to 0.84748 in.)
- Maximum inside diameter:
- 21.57 mm (0.8492 in.)
