Oil Pump Inspection

Turn the drive gear with 2 screwdrivers and make sure that it rotates smoothly.

NOTICE:

Be careful not to damage the lip of the oil seal.

Push the driven gear to one side of the body.

Using a feeler gauge, measure the body clearance between the driven gear and oil pump body.

Standard body clearance:

0.10 to 0.17 mm (0.0039 to 0.0067 in.)

Maximum body clearance:

0.17 mm (0.0067 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 (0.0028 to 0.0059 in.)

Maximum tip clearance:

0.15 mm (0.0059 in.)

Using a straightedge 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.)

Standard drive gear thickness:

Mark	Thickness
A	11.690 to 11.699 mm (0.4602 to 0.4606 in.)
B	11.700 to 11.709 mm (0.4606 to 0.4610 in.)
C	11.710 to 11.720 mm (0.4610 to 0.4614 in.)
D	11.721 to 11.730 mm (0.4615 to 0.4618 in.)
E	11.731 to 11.740 mm (0.4619 to 0.4622 in.)

Standard driven gear thickness:

Mark	Thickness
A	11.690 to 11.699 mm (0.4602 to 0.4606 in.)
B	11.700 to 11.709 mm (0.4606 to 0.4610 in.)
C	11.710 to 11.720 mm (0.4610 to 0.4614 in.)
D	11.721 to 11.730 mm (0.4615 to 0.4618 in.)
E	11.731 to 11.740 mm (0.4619 to 0.4622 in.)

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

Standard inside diameter:

38.113 to 38.138 mm (1.5005 to 1.5015 in.)

Maximum inside diameter:

38.188 mm (1.5035 in.)

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

Standard inside diameter:

21.500 to 21.526 mm (0.8465 to 0.8475 in.)

Maximum inside diameter:

21.57 mm (0.8492 in.)
