Oil Pump Inspection

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

ПРИМЕЧАНИЕ:

Be careful not to damage the oil seal lip.

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 (0.0039 to 0.0067 in.)

Maximum body clearance:

0.17 mm (0.0067 in.)

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
1	10.690 to 10.699 mm (0.4209 to 0.4212 in.)
2	10.700 to 10.709 mm (0.4213 to 0.4216 in.)
3	10.710 to 10.720 mm (0.4217 to 0.4220 in.)
4	10.721 to 10.730 mm (0.4221 to 0.4224 in.)
5	10.731 to 10.740 mm (0.4225 to 0.4228 in.)

Standard driven gear thickness:

Mark	Thickness
1	10.690 to 10.699 mm (0.4209 to 0.4212 in.)
2	10.700 to 10.709 mm (0.4213 to 0.4216 in.)
3	10.710 to 10.720 mm (0.4217 to 0.4220 in.)
4	10.721 to 10.730 mm (0.4221 to 0.4224 in.)
5	10.731 to 10.740 mm (0.4225 to 0.4228 in.)

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

Standard inside diameter:

38.11 to 38.14 mm (1.5005 to 1.5015 in.)

Maximum inside diameter:

38.19 mm (1.5035 in.)

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

Standard inside diameter:

20.50 to 21.53 mm (0.8465 to 0.8475 in.)

Maximum inside diameter:

21.57 mm (0.8492 in.)
