Improper assembly of parts that are spring loaded can cause bodily
injury.
To prevent possible injury, follow the established assembly procedure
and wear protective equipment.
1. Use Tooling (A) to install the bearings in body (4) until the bearings are even with the
outside surface of body (4). Install the bearings so the junctions in the bearings are 30 ± 15
degrees from the center line of the bearing bores and toward the outlet passage in the oil
pump.
2. Install plunger (18), plunger ring (17), and spring (16).
3. Install retainer (15) and bolts (14).
4. Install shaft assemblies (13) into body (4).
5. Use Tooling (A) to install the bearings in spacer (12). Install the bearings in the center of the
bores. Make sure that the oil holes in the bearings are in alignment with the oil holes in the
spacer. Make sure that the junctions in the bearings are in alignment with the cavity in the
spacer.
6. Use Tooling (A) to install the bearings in body (10) until the bearings are 1.52 ± 0.25 mm
(0.060 ± 0.010 inch) from the inside edge of the bearing bores. Install the bearings so the
junctions in the bearings are 30 ± 15 degrees from the center line of the bearing bores, and
toward the outlet passage. The outlet passage has a cavity between the bearing bores.
