1. Check the O-ring seals for damage. If damaged, use new parts for replacement. 2. Put oil pump (1) in position. Install the three bolts that hold the oil pump to the engine. 3. Put clean engine oil on all O-ring seals, and install pipe (2) and tube assembly (3) in the oil pump as a unit. Install two bolts that fasten the pipe assembly to the engine block.End By:a. install oil panDisassemble Oil Pump
Start By:a. remove oil pump1. Remove the bolt and washer that hold the gear on the shaft. 2. Use Tooling (A) to remove drive gear (1) from the shaft. Remove the key from shaft. 3. Remove retainer (3) for the bypass valve.4. Remove the spring and bypass valve.5. Remove cover (2) from the pump body. 6. Use Tooling (B) to remove the bearings from the cover. 7. Remove gears (5) from pump body (4).8. Use Tooling (B) to remove the bearings from the pump body.Assemble Oil Pump
1. Use Tooling (A) to install the bearings in the main pump body until they are even with the outside surface of the pump body. Install the bearings so the junctions in the bearings are 30 15 degrees from the center of the bearing bores and toward the oil pump outlet passage (2) as shown. 2. Install idler gear (1) and drive gear (3) in the oil pump body. Put clean engine oil on the bearings and gears. 3. Use Tooling (A) to install the bearings in cover (4) until they are even with the outside surface of the cover. Install the bearings so the junctions in the bearings are 30 15 degrees from the center of the bearing bores and toward the oil pump outlet passage as shown. 4. Install bypass valve (5), spring (6), spacer and the retainer in the pump body.5. Install the key on the shaft. 6. Install gear (7) on the shaft. Install the washer and bolt that holds the gear on the shaft. Tighten the bolt to a torque of 55 7 N m (41 5 lb ft).7. Make sure the pump turns freely by hand after it is assembled.End By:a. install oil pump
