2. Remove two bolts (1) to disconnect elbow (2) from the oil pump.
The oil pump idler gear is free to fall when the oil pump is removed and can cause personal injury.
3. Bend the locks down and remove bolts (3) to remove oil pump (4) from the engine. 4. Put oil pump (4) in position and install the locks and bolts to hold it. Make sure the idler gear is correctly engaged with the crankshaft gear before the bolts are tight5. Put the gasket in position and install the bolts to hold elbow (2) to the oil pump.6. Put the gasket and suction bell assembly in position and install the locks and bolts to hold these in position.End By:a. install oil panDisassemble Oil Pump

Remove the bearings from the oil pump body assembly and the scavenge pump body assembly with tooling (B).Assemble Oil Pump
1. Install the bearings in the scavenge pump body assembly with tooling (A) as follows:a. Put bearings (9) 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 centerline 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) as follows:a. Put bearings (10) 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 of the parts of the oil pump.5. Install pressure relief valve (11), cover (12) and bolt (6) in the oil pump body assembly. 6. Install gears and shafts (5) in the oil pump body assembly.7. Install spacer (4) and the two keys in shafts (5). 8. Install two gears and scavenge pump body assembly (13).9. Install key (14), drive gear (2), the washer and bolt (15). Tighten the bolt to a torque of 32 5 N m (43 7 lb.ft.)10. Install the bearing in the idler gear with tooling (A) until it is even with the outside surface of the gear.11. Install the idler gear.
The oil pump must turn freely by hand after it is assembled.
