1. Bend the locks down and remove bolts (2) and suction bell assembly (1) from the oil pan plate and oil pump. The oil pump suction bell assembly can be removed with the oil pump. 2. Remove bolts (3) that hold elbow (4) to the oil pump. 3. Bend the locks down and remove bolts (6) and (7) that hold oil pump (5) in place. Remove oil pump (5).
The oil pump idler gear is free to fall when the oil pump is removed.
Install Oil Pump
1. Put oil pump (1) in position on the engine and install the locks and bolts (3). Be sure the idler gear is engaged with the crankshaft gear before bolts (3) are tightened. 2. Put the gasket in position and install elbow (2) to the oil pump. 3. Put the gasket in place and install suction bell assembly (4) with the locks and bolts (5). Bend the locks up.end by:a) install oi panDisassemble Oil Pump
start by: a) remove oil pump 1. Remove idler gear (2). Remove bearing from gear with tooling (B) and a press.2. Remove suction bell (1) if it was not removed in the REMOVE OIL PUMP story.3. Remove the bolt and the washer from the oil pump drive gear. 4. Remove the drive gear from the shaft with tooling (A).5. Remove the key from the pump shaft.6. Remove bolts (3) from the pump body. 7. Remove body (8), two gears (7), keys and spacer (4) from the pump.8. Remove two shafts (5) and the gears.9. Remove bolts (6), the cover and the pressure relief valve from the body. 10. Remove the bearings from the oil pump body assembly and the scavenge pump body assembly with tooling (C).Assemble Oil Pump
1. Install the bearings in the scavenge pump body assembly with tooling (A) and a press as follows: a) Put bearings (1) in position on the inside of the scavenge pump body assembly with the chamfer on the bearing toward the outside of the pump body. Install the bearing until it is 1.52 mm (.060 in.) below the inside machined surface of the scavenge pump body assembly. Make sure the joints in the bearings are at an angle of 30° 15° from the center line through the bores in the scavenge pump body and toward the outlet passage of the pump. The outlet passage has a cavity between the bearing bores. 2. Install the bearings in oil pump body assembly with tooling (A) and a press as follows: a) Put bearings (2) in position on the inside of the oil pump body assembly with the chamfer on the bearings toward the outside of the pump body. Install the bearings until they are even with the outside of the pump body. Make sure the joints in the bearings are at an angle of 30° 15° from the centerline through the bearing bores and toward the outlet passage of the pump. The outlet passage has a cavity between the bearing bores.3. Check the condition of the relief valve. Check the condition and specifications for all the parts of the oil pump before it is assembled. See OIL PUMP in SPECIFICATIONS.4. Put clean engine oil on all the parts of the oil pump. 5. Install pressure relief valve (3), cover (4) and bolt (5) in the oil pump body assembly.6. Install gears and shafts (6) in the oil pump body assembly. 7. Install spacer (7) and the two keys in shafts (6). 8. Install two gears and scavenge pump body assembly (8).9. Install key (9), drive gear (11), the washer and bolt (10). Tighten the bolt to a torque of 43 7 N m (32 5 lb.ft.). 10. Install bearing (12) in idler gear (13) with tooling (B) and a press until it is even with the outside surface of the gear.11. Install idler gear (13) on the pump.12. Put the gasket and suction bell assembly (14) in position and install the locks and bolts (15) that hold it. Bend the locks up.
The oil pump must turn freely by hand after it is assembled.
