1. Remove bolts (1) and (2) that hold the oil pump to the cylinder block. Remove the oil pump (3).Install Oil Pump
1. Put the oil pump (1) in position on the cylinder block. Install the bolts that hold it.end by: a) install oil pan and plateDisassemble Oil Pump
start by: a) remove oil pump1. Remove bolt and washer that hold gear on the shaft. 2. Use tooling (A) to remove drive gear (1) from shaft. Remove the key from shaft. Put marks on the pump bodies so they can be assembled in the correct position. 3. Remove retainer (3) for bypass valve. Remove spring and bypass valve.4. Remove bolts (4) that hold pump body (2) to the main pump body. Remove the pump body (2).5. Use tooling (B) to remove the bearings from pump body (2). 6. Remove the gears (7). Put marks on the gears so they can be assembled in the same position.7. Remove the spacer (6) from the main oil pump body (5). Use tooling (C) to remove the bearings from spacer (6).8. Remove the gears from main pump body (5). 9. Use tooling (C) to remove the bearings from the main pump body.Assemble Oil Pump
1. Use tooling (A) to install the bearings (2) until they are even with the outside surface of the main pump body (1). Install the bearings (2) 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. 2. Use tooling (A) to install the bearings (3) in the spacer. Install the bearings until they are in position an equal distance in from each side of the spacer. Install the bearings with the oil holes in the bearings in alignment with the oil holes in the spacer and the junctions in the bearings in alignment with the cavity in the spacer as shown. 3. Put clean engine oil on all gears and bearings before they are assembled in the oil pump. Install the idler and drive gears (5) in the main pump body.4. Install the spacer (4) on the gear shafts with the smaller cavity out and the oil holes in the spacer toward the pump outlet passage as shown. 5. Use tooling (B) to install the bearings (6) in the pump body (7) until they are .060 .010 in. (1.52 0.25 mm) from the inside edge of the bearing bores. Install the bearings so the junctions in the bearings 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. 6. Install the pump gears (8) on the oil pump shafts in their original position.7. Install the pump body (10). Install bypass valve (9), spring (11) and retainer (12).8. Install key on shaft. 9. Install gear (13) on shaft. Install washer and bolt that hold gear on the shaft. Be sure pump turns freely after assembly.end by: a) install oil pump
