Oil Pump Inspection

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

Maximum inside diameter:

38.138 mm (1.5015 in.)

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

Maximum inside diameter:

Front side:

21.527 mm (0.8475 in.)

Rear side:

32.03 mm (1.261 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:

0.03 to 0.05 mm (0.0012 to 0.002 in.)

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

Drive and driven gears thickness:

Mark	Thickness
0	10.736 to 10.742 mm (0.42268 to 0.42291 in.)
1	10.743 to 10.749 mm (0.42296 to 0.42319 in.)
2	10.750 to 10.756 mm (0.42323 to 0.42346 in.)
3	10.757 to 10.763 mm (0.42350 to 0.42374 in.)
4	10.764 to 10.770 mm (0.42378 to 0.42401 in.)
5	10.771 to 10.777 mm (0.42405 to 0.42429 in.)
6	10.778 to 10.784 mm (0.42433 to 0.42457 in.)

Make sure that the drive gear rotates smoothly.

Remove the oil pump assembly from the torque converter.
