Usage:
start by:
a) remove fuel transfer pump
1. Drain the coolant from the cooling system.
2. Drain the oil from the oil pan.
3. Remove all bolts (1) and (2) to remove adapter (3) from the engine.
4. Remove all the bolts and remove oil pump (4) from the engine. The weight of the pump is 39 kg (85 lb).
INSTALL OIL PUMP
NOTE: The oil pump shaft must turn by hand and the pump must have oil for lubrication before it is installed.
1. Put clean engine oil on the O-ring seals and put oil pump (1) in position. Make sure the splines on the pump shaft are correctly engaged with the splines of the oil pump drive. Install the bolts to hold the oil pump in position.
2. Put the gaskets and adapter (2) in position. Install the bolts to hold the adapter and gaskets in position.
3. Fill the engine with oil to the correct level.
4. Fill the cooling system with coolant to the correct level.

DISASSEMBLE OIL PUMP
start by:
a) remove oil pump
NOTE: The pump shown in the illustrations is for the 3508 Engine.
1. Remove adapter assembly (1) from the pump.
 |
Cover (2) has spring tension on it. Loosen the bolts that hold it slowly and the same amount to remove the tension on the cover. |
 |
2. Remove the bolts, cover (2), gasket (3), spring (4) and valve spool (5) from the pump.
3. Remove cover assembly (6) and the gasket from the pump.
4. Remove cover assembly (7) from the pump.
5. Use tooling (A) to remove bearings (8) from cover assembly (7).
6. Remove shaft assemblies (10) from body assembly (9).
7. Use a press to remove gears (11) from the shaft assemblies.
8. Use tooling (A) to remove bearings (12) from body assembly (9).
ASSEMBLE OIL PUMP
NOTE: The pump shown in the illustration is for the 3508 Engine.
1. Make an alignment of bearings (1) so the joints are 45 ± 15° from a line through the center of the bearing bores as shown.
2. Use tooling (A) to install bearings (1) in the body assembly until they are 1.5 ± 0.5 mm (.059 ± 0.20 in) below the gear bore in the body assembly. Check the inside diameter of the bearings after installation. The diameter must be 31.837 ± 0.070 mm (1.2534 ± .0028 in).
3. Heat gears (2) to a maximum temperature of 316° C (600° F).
4. Install the gears on shaft assemblies (3) until they are 34.0 ± 0.5 mm (1.34 ± .020 in) from the cover end of the shaft assemblies to the face of the gears and 47.0 ± 0.5 mm (1.85 ± .020 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 ± 0.5 mm (.236 ± .02 in) above the surface of the cover assembly.
7. Use tooling (A) and 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 ± 1 mm (.236 ± .039 in) above the surface of the cover assembly. Install the gasket and cover assembly (9) on the pump.
10. Put clean engine oil on valve spool (13). Install valve spool (13), spring (12), gasket (11), cover (10) and the bolts on the pump body.
11. Install the gasket and adapter assembly (14) on the pump body.
