INSPECTION

PROCEDURE

1. INSPECT FRONT OIL PUMP AND GEAR BODY SUB-ASSEMBLY

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

NOTICE:

Be careful not to damage the oil seal lip.

2. INSPECT CLEARANCE OF FRONT OIL PUMP AND GEAR BODY SUB-ASSEMBLY

(a) Push the driven gear to one side of the body.

(b) Using a feeler gauge, measure the clearance.

Standard clearance:

0.08 to 0.15 mm (0.00315 to 0.00590 in.)

Maximum clearance:

0.15 mm (0.00590 in.)

If the clearance is greater than the maximum, replace the oil pump body sub-assembly.

Standard side clearance:

0.025 to 0.04 mm (0.000984 to 0.00157 in.)

Maximum side clearance:

0.04 mm (0.00157 in.)

Drive Gear Thickness

Mark	Thickness
1	11.547 to 11.555 mm (0.4546 to 0.4549 in.)
2	11.555 to 11.563 mm (0.4549 to 0.4552 in.)
3	11.564 to 11.571 mm (0.4553 to 0.4556 in.)
4	11.572 to 11.579 mm (0.4556 to 0.4559 in.)
5	11.580 to 11.587 mm (0.4559 to 0.4562 in.)

Driven Gear Thickness

Mark	Thickness
1	11.547 to 11.555 mm (0.4546 to 0.4549 in.)
2	11.555 to 11.563 mm (0.4549 to 0.4552 in.)
3	11.564 to 11.571 mm (0.4553 to 0.4556 in.)
4	11.572 to 11.579 mm (0.4556 to 0.4559 in.)
5	11.580 to 11.587 mm (0.4559 to 0.4562 in.)

3. INSPECT FRONT OIL PUMP AND GEAR BODY SUB-ASSEMBLY

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

Standard inside diameter:

43.113 to 43.138 mm (1.6974 to 1.6983 in.)

Maximum inside diameter:

43.188 mm (1.7003 in.)

If the inside diameter is greater than the maximum, replace the oil pump body sub-assembly.

4. INSPECT STATOR SHAFT ASSEMBLY

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

Standard inside diameter:

22.500 to 22.526 mm (0.8858 to 0.8868 in.)

Maximum inside diameter:

22.570 mm (0.8886 in.)

If the inside diameter is greater than the maximum, replace the oil pump body sub-assembly.
