2.
Selecting the pump rotor and slide.
A.
Use a vernier micrometer to measure the thickness of the original pump rotor and slide (Figure 2). To obtain the most accurate reading,
measure on flat undamaged surfaces.
B.
Using the original parts measurements, order service replacement parts from the following selective charts.

NOTE:
The replacement part will provide the same clearance as the original oil pump assembly. The proper end clearance specification is 0.020 to
0.050 mm. (.0008" to .002"). This dimension cannot be measured with a straight edge and feeler gage.
C.
Hone both sides of the replacement rotor and slide with a fine oil stone to remove any burrs, and measure the parts with a vernier micrometer to
assure proper thickness.
NOTE:
Incorrect rotor thickness could result in a damaged oil pump assembly, and/or low oil pressure. Incorrect slide thickness could result in
incorrect transmission line pressure.

Other Oil Pump Overhaul Parts:
A.
Pump slide seal package (P/N 8634906) includes items #4, #5, #10 and #11 of Figure 1. Pump vane kit (P/N 8634904) includes items #12
and #15 of Figure 1.
4.
Assembly:
A.
Reassemble the oil pump assembly following procedures outlined in the Service Information Manual.
B.
After assembling the oil pump into the transmission, install the torque converter and check for proper rotor and slide clearance by rotating the
converter by hand. The converter should turn freely. If the converter does not turn freely, remove the converter, disassemble the oil pump and
recheek the thickness of the pump rotor and slide.
C.
If the converter does turn freely in Step B above, install the transmission into the vehicle.
D.
Before road testing the vehicle, install gage into the line pressure tap of the transmission (driver's side of vehicle) and check oil pressure.
Refer to the appropriate model year Service Information Manual for oil pressure specifications.
For warranty purposes, use labor Operation No. K7120 at 3.2 hours.
