At operating temperature, the engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot water or steam. Any contact can cause severe burns. Look at the sight gauge to check the coolant level. The coolant level should be in the green range. If necessary, remove the fill cap only after the engine has been stopped and the cap is cool enough to remove with your bare hand. Remove the cooling system fill cap slowly to relieve pressure. Cooling system condition contains alkali that can cause personal injury. Avoid contact with the skin and eyes and do not drink. Allow cooling system components to cool before draining. |
 |
1. Drain the coolant from the cooling system into a suitable container for storage or disposal.
|
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact the skin. |
|
2. Drain the oil from the oil pan into a suitable container for storage or disposal.
3. Remove all bolts (1) and (2) to remove adapter (3) from the engine.
4. Remove all the bolts and use two people to remove oil pump (4) from the engine. The weight of the oil 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 use two people to put oil pump (1) in position. The weight of the oil pump is 39 kg (85 lb). Make sure the splines on the pump shaft are correctly engaged with the splines of 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 correct level. See the Operation & Maintenance Manual.
4. Fill the cooling system with coolant to the correct level. See the Operation & Maintenance Manual.

Disassemble Oil Pump
Start By:
a. remove oil pump
1. Remove adapter assembly (1) from the pump
|
Cover (2) has spring tension on it. Loosen the bolts that hold it slowly and evenly 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 Tool (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 Tool (A) to remove bearings (12) from body assembly (9).
Assemble Oil Pump
1. Make an alignment of bearings (1) so the joints are 45 ± 15 degrees from a line through the center of the bearing bores as shown.
2. Use Tool (A) to install bearings (1) in the body assembly until they are 1.50 ± 0.50 mm (.059 ± .020 in) below the gear bore in the body assembly. Check the inside diameter of the bearings after installation. The diameter must be 31.937 ± 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 ± .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 6.00 ± 0.5 mm (.236 ± .02 in) above the surface of the cover assembly.
7. Use Tool (A) and install bearings (7) in cover assembly (6) with the joints of the bearings in the position 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 6.00 ± 1.00 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.
