OIL PUMP (for Sedan) > INSPECTION |
1. INSPECT STATOR SHAFT ASSEMBLY |
Using a dial indicator, measure the inside diameter of the stator shaft bushings.
- Standard inside diameter:
- 21.500 to 21.526 mm (0.84646 to 0.84748 in.)
- Maximum inside diameter:
- 21.526 mm (0.84748 in.)
Install the input shaft assembly onto the stator shaft assembly and check that the input shaft assembly turns smoothly.
- NOTICE:
- Replace the stator assembly with a new one if it moves roughly or makes unusual noise.
- Inspect the input shaft's contact surface with the bearing when replacing, and replace the input shaft with a new one if any damage or discoloration is found.
2. INSPECT OIL PUMP GEAR CLEARANCE |
Measure the clearance between the tips of the driven gear teeth and the drive gear teeth.
- Standard tip clearance:
- 0.07 to 0.15 mm (0.0028 to 0.0059 in.)
- Maximum tip clearance:
- 0.15 mm (0.0059 in.)
Push the driven gear to one side of the body. Using a feeler gauge, measure the clearance.
- Standard body clearance:
- 0.10 to 0.15 mm (0.0039 to 0.0059 in.)
- Maximum body clearance:
- 0.15 mm (0.0059 in.)
Using a steel straight edge and feeler gauge, measure the side clearance of both gears.
- Standard side clearance:
- 0.02 to 0.05 mm (0.0008 to 0.0020 in.)
- Maximum side clearance:
- 0.05 mm (0.0020 in.)
- Drive gear thickness:
No. Thickness mm (in.) 1 9.44 to 9.45 (0.3709 to 0.3713) 2 9.45 to 9.46 (0.3713 to 0.3717) 3 9.46 to 9.47 (0.3717 to 0.3721) 4 9.47 to 9.48 (0.3721 to 0.3725) 5 9.48 to 9.49 (0.3725 to 0.3729)
- Driven gear thickness:
No. Thickness mm (in.) 1 9.44 to 9.45 (0.3709 to 0.3713) 2 9.45 to 9.46 (0.3713 to 0.3717) 3 9.46 to 9.47 (0.3717 to 0.3721) 4 9.47 to 9.48 (0.3721 to 0.3725) 5 9.48 to 9.49 (0.3725 to 0.3729)
3. INSPECT FRONT OIL PUMP 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 (1.50050 to 1.50149 in.)
- Maximum inside diameter:
- 38.138 mm (1.50149 in.)
