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 shaft assemblies (6) in the oil pump body assembly.7. Install spacer (7). Install the key in the shaft assembly.8. Install the two gears on the shaft assemblies. 8. Install scavenge pump body assembly (8) and the bolts that hold it.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 the bearing in the idler gear with tooling (A) and a press until it is even with the outside surface of the gear.11. Install the suction bell on the oil pump. Install the idler gear on the oil pump.
The oil pump must turn freely by hand after it is assembled.
