Oil Pump Inspection

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

NOTICE:

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 clearance:

0.08 to 0.15 mm (0.0031 to 0.0059 in.)

Maximum clearance:

0.15 mm (0.0059 in.)

Using a straight edge and feeler gauge, measure the side clearance of both gears.

Standard side clearance:

0.025 to 0.04 mm (0.0010 to 0.0016 in.)

Maximum side clearance:

0.04 mm (0.0016 in.)

Drive gear thickness:

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

Driven gear thickness:

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

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.)

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.)
