Oil Pump (For Hatchback) Inspection

Using a caliper gauge, measure the inside diameter of the stator shaft bushings.

Standard inside diameter:

21.500 to 21.526 mm (0.846 to 0.847 in.)

Maximum inside diameter:

21.526 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 shaft 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.

Measure the clearance between the tips of the front oil pump driven gear teeth and the front oil pump 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.)

Push the front oil pump driven gear to one side of the body. Using a feeler gauge, measure the clearance.

Standard body clearance:

0.10 to 0.15 mm (0.00394 to 0.00591 in.)

Maximum body clearance:

0.15 mm (0.00591 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 0.00197 in.)

Maximum side clearance:

0.05 mm (0.00197 in.)

Drive Gear Thickness:

Part No.	Mark	Thickness mm (in.)
35321-52060	1	9.44 to 9.45 (0.3709 to 0.3713)
35321-52070	2	9.45 to 9.46 (0.3713 to 0.3717)
35321-52080	3	9.46 to 9.47 (0.3717 to 0.3721)
35321-52090	4	9.47 to 9.48 (0.3721 to 0.3725)
35321-52100	5	9.48 to 9.49 (0.3725 to 0.3729)

Driven Gear Thickness:

Part No.	Mark	Thickness mm (in.)
35322-52060	1	9.44 to 9.45 (0.3709 to 0.3713)
35322-52070	2	9.45 to 9.46 (0.3713 to 0.3717)
35322-52080	3	9.46 to 9.47 (0.3717 to 0.3721)
35322-52090	4	9.47 to 9.48 (0.3721 to 0.3725)
35322-52100	5	9.48 to 9.49 (0.3725 to 0.3729)

Using a caliper gauge, measure the inside diameter of the front oil pump body bushing.

Standard inside diameter:

38.113 to 38.138 mm (1.5005 to 1.5015 in.)

Maximum inside diameter:

38.138 mm (1.5015 in.)
