1. Remove the alternator and mounting bracket if so equipped. See Alternator (An Attachment).
2. Drain the coolant from the cooling system.
3. Remove the bolts, and remove elbow (2) from tube (1) and the water line adapter.
4. Remove the bolts, and remove water line adapter (4) and tube (3) from the engine.
5. Remove the bolts, and remove elbow (5) from the top of the oil pump and tube (6).
6. Remove the bolts to disconnect elbow (7) from the bottom of the oil pump.
7. Fasten a hoist to oil pump (8) with tooling (A). Remove the bolts, and remove oil pump (8) from the oil pump drive. The weight of the pump is 39 kg (86 lb.).
| NOTICE |
|---|
The oil pump shaft must turn by hand, and the pump must have oil for lubrication before it is installed. |
8. Fasten a hoist to oil pump (8) with tooling (A), and put pump (8) in position. Make sure the splines on the pump shaft are engaged correctly with the splines of the oil pump drive, and install the bolts to hold the pump in position.
9. Install the bolts to connect elbow (7) to the bottom of the oil pump.
10. Make sure the O-ring seals on tube (6) and elbow (5) are in position, and put clean engine oil on the seals. Put elbow (5) in position on tube (6) and the top of the oil pump. Install the bolts to hold these in position.
11. Make sure the O-ring seal on the end of tube (3) is in position, and put clean engine oil on it. Put the gasket, adapter (4) and tube (3) in position, and install the bolts to hold these in position.
12. Make sure the O-ring seal on the end of tube (1) is in position, and put clean engine oil on it. Put the gasket and elbow (2) in position on tube (1) and the water line adapter. Install the bolts to hold these in position.
13. Fill the cooling system with coolant to the correct level. See the Maintenance Guide.
14. Install the alternator mounting bracket and alternator if so equipped. See Alternator (An Attachment).

1. Remove bolts (1), cover (2), gasket (3), spring (4) and valve spool (5) from the pump body.
2. Remove cover assembly (6) and the gasket from the pump body.
3. Remove cover assembly (7) from the pump body.
4. Use tooling (A) to remove bearings (8) from cover assembly (7).
5. Remove shaft assemblies (10) from body assembly (9).
6. Use a press to remove gears (11) from the shaft assemblies.
7. Use tooling (A) to remove bearings (12) from body assembly (9).
Assemble Oil Pump
1. Make an alignment of bearings (1) so that the joints are 45 ± 15° from a line through the center of the bearing bores as shown.
2. Use tooling (A) to install bearing (1) in the body assembly until they are 1.5 ± 0.5 mm (.06 ± .02 in.) below the gear bore in the body assembly. Check the inside diameter of the bearings after installation. The diameter must be 31.811 ± 0.013 mm (1.2524 ± .0005 in.).
3. Heat gears (2) to a maximum temperature of 316° (600°F).
4. Install the gears on shaft assemblies (3) until they are 34.0 ± 0.5 mm (1.34 ± .02 in.) from the cover end of the shaft assemblies to the face of the gears and 47.0 ± 0.5 mm (1.85 ± .02 in.) from the fuel pump drive end of shaft assembly (4).
5. Install shaft assemblies (3) and (4) in the body assembly.
6. Make sure dowels (5) and (8) are installed in cover assembly (6) so they extend 6.0 ± 0.5 mm (.24 ± .02 in.) above the surface of the cover assembly.
7. Use tooling (A) to install bearings (7) in cover assembly (6) with the joints of the bearings in the positions as shown.
8. Put cover assembly (6) in position, and tighten the bolts to hold it to the body assembly.
9. Make sure the two pins in cover assembly (9) are installed so they extend 6.0 ± 1.0 mm (.24 ± .04 in.) above the surface of the cover assembly. Install the gasket and cover assembly (9) on the body assembly.
10. Put clean engine oil on valve spool (13). Install valve spool (13), spring (12), gasket (11), cover (10) and the bolts in the body assembly.
