Oil Pump Disassembly

Place the oil pump body on the torque converter.

Remove the 2 oil rings.

Remove the 13 bolts, and then remove the stator shaft from the oil pump body.

Remove the oil pump body from the torque converter clutch.

Using a dial indicator, measure the inside diameter of the oil pump body bush.

Maximum inside diameter:

38.19 mm (1.5035 in.)

Using a dial indicator, measure the inside diameter of the stator shaft bush.

Maximum inside diameter:

Front side	Rear side
21.58 mm (0.8496 in.)	27.08 mm (1.0661 in.)

Push the driven gear to one side of the body.

Using a feeler gauge, measure the clearance.

Standard body clearance:

0.07 to 0.15 mm (0.00276 to 0.00591 in.)

Maximum body clearance:

0.2 mm (0.00787 in.)

Using a feeler gauge, measure the tip clearance between the driven gear teeth and drive gear teeth.

Standard tip clearance:

0.004 to 0.248 mm (0.000157 to 0.00976 in.)

Maximum tip clearance:

0.3 mm (0.0118 in.)

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

Standard side clearance:

0.02 to 0.05 mm (0.000787 to 0.00197 in.)

Maximum side clearance:

0.1 mm (0.00394 in.)

HINT:

There are 5 different thicknesses for drive and driven gears.

Using a screwdriver, pry out the oil seal.

NOTICE:

Be careful not to damage the bush and the oil pump body.
