Start By: a. remove oil pump 1. Remove the bolt and pull pipe assembly (1) out of the pump body. 2. Remove O-ring seal (2) from pipe assembly (1).3. Remove clip (4) and screen assembly (3) from the bell assembly. 4. Remove the bolts and washers to remove brackets (5), (6) and bell assembly (7) from pipe assembly (1). 5. Remove bolt (9), thrust plate (8) and idler gear (10) from the shaft assembly. 6. Use tool group (A) and a press to remove the bearing from idler gear (10). 7. Remove the bolts and shaft assembly (12) from the pump body.8. Remove the bolt and washer (11) that hold the pump drive gear. 9. Use tooling (A) and (B) to remove drive gear (13) from the pump. Remove the key from the pump shaft. 10. Remove the bolts and body (15) from the spacer and body (14). 11. If necessary, use a press and tool group (A) to push bearings (16) from body (15). 12. Remove gears (18) from the shaft assemblies.13. Remove spacer (17) from body (14). 14. If necessary, remove bearings (19) from spacer (17). 15. Remove shaft assemblies (20) and (21) from body (14). 16. Remove retainer (22), spacer (25), spring (24) and plunger (23) from body (14). 17. If necessary, use tool group (A) and a press to push bearings (26) out of body (14). The following steps are for the assembly of the oil pump.18. Make sure all of the parts are clean and free of dirt and foreign material. Put clean engine oil on the parts at assembly. 19. Use tool group (A) to install bearings (26) until they are even with the outside surface of main pump body (14). Install bearings (26) so the junctions in the bearings are 30° 15° from the center line of the bearing bores and toward the oil pump outlet passage as shown.20. Install plunger (23), spring (24), spacer (25), retainer (22) and the bolts in body (14) as shown.21. Install shaft assemblies (20) and (21) in body (14).22. Use tool group (A) to install bearings (19) in spacer (17). Install the bearings in the center of their bores. Make sure the oil holes in the bearings are in alignment with the oil holes in the spacer and the junctions in the bearings in alignment with the cavity in the spacer.23. Install spacer (17) over the shaft assemblies on body (14).24. Install gears (18) on the shaft assemblies. 25. Use tool group (A) to install bearings (16) in pump body (15) until they are 1.52 0.25 mm (.060 .010 in.) from the inside edge of the bearing bores. Install the bearings so the junctions in the bearing are 30° 15° from the center line of the bearing bores, and toward the outlet passage. The outlet passage has a cavity between the bearing bores.26. Put body (15) in position over the shaft assemblies on the spacer and body (14). Install the bolts to hold the pump together.27. Install the key and drive gear (13) on the shaft assembly.28. Install washer (11) and the bolt to hold the drive gear. Tighten the bolt to a torque of 55 7 N m (41 5 lb.ft.). Install shaft assembly (12) on pump body.29. Use tool group (A) and a press to install the bearing in idler gear (10).30. Put idler gear (10) in position on the shaft assembly. Install thrust plate (8) and the bolt to hold gear (10). Make sure the side of thrust plate (8), with the oil groove, is toward gear (10). The oil pump gears must turn freely by hand after assembly.31. Put the bolts, washers, brackets (5) and bracket (6) in position on pipe assembly (1). Put pipe assembly (1) in position on bell assembly (7) and tighten the bolts.32. Install O-ring seal (2) on pipe assembly (1).33. Install screen assembly (3) in bell assembly (7). Install clip (4) to hold screen assembly (3) in position.34. Put pipe assembly (1) in position in the pump body and install the bolt.End By: a. install oil pump
