3204 VEHICULAR ENGINE FOR 943 & 953 TRACK-TYPE LOADERS Caterpillar


Engine Oil Cooler (953 & Later 943)

Usage:

Remove Engine Oil Cooler (953 & Later 943)

NOTE: The radiator guard and engine enclosure were removed for better photo illustration only.

1. Close the fuel valve on the fuel tank. Drain the coolant from the engine.

2. Disconnect the wires from fuel pressure switch (1) on the fuel filter base.

NOTE: Put plugs or caps on all fuel line openings when the fuel lines are disconnected.

3. Remove fuel lines (2) and (3).

4. Remove fuel lines (4) and (5).

5. Remove water line (6) from the oil cooler and the elbow on the timing gear cover.

6. Remove two bolts (8) and bracket (7) from the oil manifold. Move the bracket clear of the oil cooler.

7. Loosen hose clamp (9), and disconnect the water line from cover (11).

8. Remove 10 bolts (10), and remove cover (11) and the core assembly as a unit from the oil manifold.

9. Remove cover (11) from the core assembly.

10. Carefully lift out each side of divider (12); then slide it out from between the plates of the core.

Install Engine Oil Cooler (953 & Later 943)

1. Install the divider between the fifth and sixth plates from the flange and on the end opposite from hole (2) in the flange as shown. Hole (2) does not have the same spacing as the other holes. Install the divider with boss (1) on the divider in the relation shown to hole (2). The divider must be installed evenly around the circumference of the plates so the cover will make a seal correctly when it is installed.

2. Install the gasket and cover (3) on the core as shown.

3. Put the gasket, oil cooler core and cover (3) in position on the oil manifold. Install the bolts that hold it in place, and connect water line (4) to the cover.

4. Put bracket (5) in position on the oil manifold, and install the two bolts that hold it in place.

5. Install water line (6) as shown.

6. Install fuel lines (7) and (8).

7. Install fuel lines (9) and (10).

8. Connect the two wires to fuel pressure switch (11).

9. Fill the engine to the correct level with coolant. See the Maintenance Guide.

10. Open the fuel valve on the fuel tank.

11. Prime the fuel system. See Priming Fuel System in the Maintenance Guide.
