Oil Pump Inspection

Using a dial indicator, measure the inside diameter of the stator shaft bushings.

Standard inside diameter:

21.50 to 21.52 mm (0.846 to 0.847 in.)

Maximum inside diameter:

21.52 mm (0.847 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.

Using a feeler gauge, 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 (0.00275 to 0.00590 in.)

Maximum tip clearance:

0.15 mm (0.00590 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 (0.00393 to 0.00590 in.)

Maximum body clearance:

0.15 mm (0.00590 in.)

Using a steel straightedge and feeler gauge, measure the side clearance of both gears.

Standard side clearance:

0.02 to 0.05 mm (0.000787 to 0.00196 in.)

Maximum side clearance:

0.05 mm (0.00196 in.)

Drive Gear Thickness:

No.	Thickness (mm (in.))
1	9.440 to 9.449 (0.3717 to 0.3720)
2	9.450 to 9.459 (0.3720 to 0.3724)
3	9.460 to 9.470 (0.3724 to 0.3728)
4	9.471 to 9.480 (0.3729 to 0.3732)
5	9.481 to 9.490 (0.3733 to 0.3736)

Driven Gear Thickness:

No.	Thickness (mm (in.))
1	9.440 to 9.449 (0.3717 to 0.3720)
2	9.450 to 9.459 (0.3720 to 0.3724)
3	9.460 to 9.470 (0.3724 to 0.3728)
4	9.471 to 9.480 (0.3729 to 0.3732)
5	9.481 to 9.490 (0.3733 to 0.3736)

Using a dial indicator, measure the inside diameter of the oil pump body bushing.

Standard inside diameter:

38.12 to 38.13 mm (1.500 to 1.501 in.)

Maximum inside diameter:

38.13 mm (1.501 in.)
