INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY

INSPECT STATOR SHAFT ASSEMBLY

INSPECT CLEARANCE OF OIL PUMP ASSEMBLY

INSPECT OIL PUMP DRIVE GEAR ROTATION

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

• Standard inside diameter:
• 38.138 mm (1.5015 in.)

If the inside diameter is greater than the standard inside diameter, replace the oil pump body.

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

• Standard inside diameter:
• 21.527 mm (0.8475 in.)

If the inside diameter is greater than the standard inside diameter, replace the stator shaft.

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.)

If the body clearance is greater than the standard clearance, check the drive gear, the driven gear and the pump body.

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.)

If the tip clearance is greater than the standard clearance, check the drive gear, the driven gear and the pump body.

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.)
  If the side clearance is greater than the standard thickness, check the drive gear, the driven gear and the pump body.

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.
