77. Transmission Oil Pump Assemble

^ Tools Required
- J 21368 Pump Body and Cover Alignment Band
- J 36850 Assembly Lubricant





1. Assemble the oil pump cover (206) and the oil pump body (203).





Important: The round end on the vent passage splash shield (239) fits into the hole in the oil pump cover. The slotted hole in the vent passage splash shield fits under the bolt head.

2. Install the vent passage splash shield (239).
3. Install the oil pump cover bolts (220). Tighten the bolts with your fingers only.





4. Install an oil pump to case bolt and seal assembly (3) into an oil pump bolt hole.

Important: The outside diameter of the oil pump body and oil pump cover must be properly aligned and then the alignment band can be tightened. This ensures that the oil pump will fit into the transmission case opening and maintains maximum oil pump efficiency.

5. Install the J21368 onto the transmission oil pump assembly and tighten.

Notice: Refer to Fastener Notice in Service Precautions.

6. Tighten the five oil pump cover bolts (220).
^ Tighten the bolts to 24 Nm (18 ft. lbs.) in an alternating pattern.
7. Remove the J 21368 and the oil pump to case bolt and seal assembly (3).





Important: Coat the transmission oil pump seat (5) with J 36850 or equivalent. This will ease assembly and prevent damage to the seal.

8. Install the transmission oil pump seal (5).





Notice: Do not overexpand the oil seal as it may become damaged.

9. Install the new overrun clutch housing oil seal rings (219) onto the oil pump assembly.
10. Ensure that the overrun clutch housing oil seal rings (219) move freely in the grooves.
11. Use J 36850 or equivalent in order to keep the overrun clutch housing oil seal rings in place.
