Information:
1. Remove oil supply tube (3), suction bell (2) and suction bell tube (1). 2. Remove bolts (4) that hold the oil pump to the cylinder block and remove oil pump (5).Install Oil Pump
1. Put oil pump (3) in position on the engine. Install the bolts that hold the oil pump to the cylinder block.2. Put clean oil on the O-ring seals of the tubes.3. Install suction bell tube (2), suction bell and oil supply tube (1).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) and remove drive gear (1) from the shaft. Remove the key from the 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) and remove the bearings from the cover. 7. Remove gears (5) from pump body (4).8. Use tooling (B) and remove the bearings from pump body (4).Assemble Oil Pump
1. Use tooling (A) to install the bearings in the pump body. Install the bearings so the split in the bearings is 30° 15° from the center line of the oil pump outlet passage (2). 2. Install idler gear (1) and drive gear (3) in the oil pump body. Put clean engine oil on the bearings and the gears. 3. Use tooling (A) and install the bearings in cover (4). Install the bearings so the split in the bearings is 30° 15° from the center line of the bearing bores toward oil pump outlet passage (2).4. Install bypass valve (5), spring (6) and the retainer.5. Install the key on the shaft. 6. Install gear (7) on the shaft. Install the washer and bolt that hold the gear on the shaft. Be sure the pump turns freely after assembly.end by:a) install oil pump
