2. Remove bolts (1), (2), (3) and (6) to remove adapter (5) from the engine. It may be desirable to remove two fuel lines (4), however it is not necessary to remove adapter (5). If fuel lines are removed, remember to first shut off fuel supply. 3. Remove elbow (7) and tube (8) from the oil pump.4. Remove the flange and tube (9) from the oil cooler bonnet.
Typical Example5. Use tool (A) to fasten a hoist to oil pump (10).6. Remove bolts (11) and (12). Remove oil pump (10). The weight of the oil pump is 39 kg (85 lb). The following steps are for the installation of the oil pump.
The oil pump must turn freely by hand, and the pump must have oil for lubrication before it is installed.
7. Put clean engine oil on the O-ring seals. Use tool (A) and a hoist to position oil pump (10). Make sure the splines on the pump shaft are correctly engaged with the splines of the oil pump drive. Install bolts (11) and (12) that hold the pump in position.8. Put clean engine oil on the O-ring seals and install tube (8) in the by-pass elbow. Put elbow (7) in position on tube (8) and the oil pump. Install the bolts to hold it in place.9. Put clean engine oil on the O-ring seals and install tube (9) and the flange as a unit in the oil cooler bonnet.10. Put the gaskets and adapter (5) in position. Install bolts (1), (2), (3) and (6) to hold them in position.11. If fuel lines (4) were removed, install them and open the fuel supply.12. Fill the cooling system with coolant to the correct level. See the Maintenance Manual. 2. Remove bolts (1), (2), (3) and (6) to remove adapter (5) from the engine.

Cover (2) has spring tension under it. To prevent personal injury, loosen bolts (1) slowly and the same amount to remove the tension under the cover.
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). The following steps are for assembly of the oil pump. 8. Make an alignment of bearings (12) so that the joints are 45 15° from a line through the center of the bearing bores as shown.9. Use tooling (A) to install bearing (12) 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).10. Heat gears (11) to a maximum temperature of 316° C (600° F).11. Install the gears on shaft assemblies (10) 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 (10). 12. Install shaft assemblies (10) in the body assembly. 13. Make sure dowels (13) and (14) are installed in cover assembly (8) so they extend 6.0 0.5 mm (.24 .02 in) above the surface of the cover assembly.14. Use tooling (A) to install bearings (8) in cover assembly (6) with the joints of the bearings in the positions as shown. Put cover assembly (6) in position, and tighten the bolts to hold it to the body assembly.15. Make sure the two pins in cover assembly (6) 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 (6) on the body assembly.16. Put clean engine oil on valve spool (5). Install valve spool (5), spring (4), gasket (3), cover (2) and the bolts in the body assembly.End By:a. install oil pump
