Oil Pump Components Assemble





1. Inspect the oil pump for:
^ Worn, scored or gouged pump slide (214)
^ Cracks, wear or damage to the rotor (210) or the vanes (211)
^ Cuts or damage to the seals (212, 213, 220, 221)
^ Broken priming springs (222, 223)
^ Damaged oil pump drive shaft bearing (208) (the bearing is not serviced separately from the rotor).





2. Inspect the oil pump body (202) for:
^ Porosity
^ A worn, scored or damaged pump pocket
^ Interconnected oil passages
^ Damaged machined surfaces
3. Inspect the pump outlet screen assembly (219) for damage or debris.
4. Inspect the oil pump cover (201) for cracks, wear or gouges from the pump vanes.





Important: Laser marks on the oil pump body indicate the size of the selective parts which were used in assembly. If the correct parts are not selected for replacement, damage to the oil pump and to the transmission will occur.

5. Measure the pump rotor (210).
6. Select the proper replacement size.





7. Measure the oil pump vanes (211).
8. Select the proper replacement size.





9. Measure the oil pump slide (214).
10. Select the proper replacement size.





11. Insert the pump outlet screen assembly (219).
12. Insert the pump slide seal support (221) and the pump slide seal (220) into the slot on the pump slide (214).
13. Insert the pump slide (214) and the slide pivot pin (215) into the pump body (202).
14. Install the outer and the inner priming springs (222, 223) as an assembly into the pump body (202).
15. Install the first vane ring (209) into the pump body (202).
16. Insert the pump slide O-ring seal (213) and the pump slide oil seal ring (212) into the pump slide (214).
17. Insert the rotor (210) into the pump body (202).
18. Install the pump vanes (211) into the rotor (210). The pump vanes (211) must be flush with the top of the rotor (210).
19. Install the second vane ring (209) onto the top of the rotor (210).

Notice: Refer to Fastener Notice in Service Precautions.

20. Install the pump cover (201) and the bolt (205).
^ Tighten the bolt to 8 Nm (70 inch lbs.).





21. Install the oil pump assembly (200) onto the control valve assembly (300).





22. Install the two pump body to case bolts (206) and the nine pump cover to case cover bolts (207).
^ Tighten the bolts to 12 Nm (106 inch lbs.).
