Engine
Disassembly and Assembly
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°+ 150 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.
