Oil Pump Inspection

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

Standard inside diameter:

38.138 mm (1.5015 in.)

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

Standard inside diameter:

21.527 mm (0.8475 in.)

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.)

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

Standard tip clearance:

0.070 to 0.150 mm (0.0028 to 0.0059 in.)

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

Standard side clearance:

0.02 to 0.04 mm (0.00079 to 0.00157 in.)

There are 7 different thicknesses for the drive and driven gears.

Drive and driven gears thickness:

Mark	Thickness
0	9.946 to 9.952 mm (0.39157 to 0.39181 in.)
1	9.953 to 9.959 mm (0.39185 to 0.39209 in.)
2	9.960 to 9.966 mm (0.39213 to 0.39236 in.)
3	9.967 to 9.973 mm (0.39240 to 0.39264 in.)
4	9.974 to 9.980 mm (0.39268 to 0.39291 in.)
5	9.981 to 9.987 mm (0.39295 to 0.39319 in.)
6	9.988 to 9.994 mm (0.39323 to 0.39346 in.)

Make sure that the drive gear rotates smoothly.

Remove the oil pump assembly from the torque converter.
