Oil Pump Inspection

Using a vernier caliper and straightedge, measure the distance between the No. 1 brake piston return spring sub-assembly end and the straightedge.

Standard thickness:

5.72 mm (0.255 in.)

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

Maximum inside diameter:

Front side:

25.926 mm (1.0207 in.)

Rear side:

35.251 mm (1.3878 in.)

Push the front oil pump driven gear to one side of the front oil pump body sub-assembly.

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

Standard body clearance:

0.10 to 0.17 mm (0.00394 to 0.00669 in.)

Using a feeler gauge, measure the clearance between the front oil pump driven gear teeth and front oil pump drive gear teeth.

Standard tip clearance:

0.065 to 0.171 mm (0.00256 to 0.00673 in.)

Using a steel straightedge and feeler gauge, measure the clearance between both gears and the straightedge.

Standard side clearance:

0.03 to 0.05 mm (0.00119 to 0.00196 in.)

HINT:

There are 5 different thicknesses for the front oil pump drive gear and front oil pump driven gear.

Front Oil Pump Drive Gear Thickness:

Part No.	Mark	Thickness
35321-60160	A	12.590 to 12.599 mm (0.4957 to 0.4960 in.)
35321-60170	B	12.600 to 12.609 mm (0.4961 to 0.4964 in.)
35321-60180	C	12.610 to 12.620 mm (0.4965 to 0.4968 in.)
35321-60190	D	12.621 to 12.630 mm (0.4969 to 0.4972 in.)
35321-60200	E	12.631 to 12.640 mm (0.4973 to 0.4976 in.)

Front Oil Pump Driven Gear Thickness:

Part No.	Mark	Thickness
35322-60160	A	12.590 to 12.599 mm (0.4957 to 0.4960 in.)
35322-60170	B	12.600 to 12.609 mm (0.4961 to 0.4964 in.)
35322-60180	C	12.610 to 12.620 mm (0.4965 to 0.4968 in.)
35322-60190	D	12.621 to 12.630 mm (0.4969 to 0.4972 in.)
35322-60200	E	12.631 to 12.640 mm (0.4973 to 0.4976 in.)

Place the oil pump assembly on the torque converter assembly.

Make sure that the drive gear rotates smoothly.
