Usage:
 |
At operating temperature, the engine cooling system is hot and under pressure. Steam can cause personal injury. Check the coolant level only after the engine has been stopped and the fill cap on the recovery tank and the radiator are cool enough to touch with your bare hand. Remove the fill caps slowly to relieve pressure. Cooling system conditioner contains alkali. Avoid contact with skin and eyes to prevent personal injury. |
 |
1. Release the pressure in the cooling system by slowly loosening the fill cap on the recovery tank and the radiator.
2. Drain the coolant from the cooling system. The capacity of the cooling system is 17 liters (4.4 U.S. gal).
|
At operating temperature, the hydraulic oil tank is hot and under pressure. Hot oil can cause burns. Remove the fill cap on the hydraulic oil tank only when the engine is stopped, and the fill cap is cool enough to touch with your bare hand. |
|
3. Release the pressure in the hydraulic system by slowly loosening the fill cap located on top of the hydraulic oil tank.
4. Drain the oil from the hydraulic oil tank. The capacity of the hydraulic oil tank is 57 liters (14.8 U.S. gal).
5. Disconnect three hoses (2) from the recovery tank.
6. Remove four locknuts (3) and the washers that hold the recovery tank to the operators platform. Remove recovery tank (1).

7. Remove one socket head bolt (4) that holds the hydraulic lines, wiring harness and the governor control cable to the bracket on the bottom side of the operators platform.
8. Remove access cover (5) from the operators platform.
9. Remove ten bolts (6) and two fan guards (7).
10. Remove the bolt, washer and locknut (8) from the radiator support bracket.
11. Disconnect upper radiator hose (9) and the lower radiator hose from the radiator.
12. Remove four bolts (10), the washers and locknuts that hold step (11) in place. Remove the step.

13. Disconnect two hydraulic hoses (12) from under the operators platform. Put plugs in the hoses to keep dirt and debris out of the hydraulic system.
14. Remove the bolt and clip to remove hose (13) from the side of the radiator. Move the hose clear of the radiator.

15. Disconnect hydraulic hose (15) from under the radiator. Put a plug in the hose to keep dirt and debris out of the hydraulic system.
16. Remove two locknuts (14), the washers and shock mount rings that hold the radiator and hydraulic oil cooler to the front engine mount.

During removal of the fan assembly, do not damage the hydraulic oil cooler core. |
17. Remove the six bolts that hold the fan assembly in position. Remove the fan assembly.
| NOTICE |
|---|
During removal of the radiator, hydraulic oil cooler and fan shroud, do not damage the radiator core or the hydraulic oil cooler core. |
18. Tilt the radiator, hydraulic oil cooler and fan shroud away from the engine. Using two persons, remove the radiator, hydraulic oil cooler and fan shroud from the machine. The weight of the unit is 39 kg (85 lb).
19. Remove six bolts (16) and the washers that hold the radiator, hydraulic oil cooler and the fan shroud together. Separate the components. The weight of the radiator is 18 kg (40 lb). The weight of the hydraulic oil cooler core is 11 kg (25 lb). The weight of the shroud is 9 kg (20 lb).
NOTE: The following steps are for the installation of the recovery tank, hydraulic oil cooler and radiator.
| NOTICE |
|---|
Do not reuse elastic filled locknuts during installation of the recovery tank, hydraulic oil cooler and radiator. The used locknuts should be discarded and replaced with new parts. |
20. To make reassembly of the hydraulic oil cooler, radiator, fan shroud and shims (if so equipped) easier, assemble the components while thy are flat on the floor. Connect the hydraulic oil cooler, radiator and fan shroud togeher with six bolts (16).
| NOTICE |
|---|
During installation of the hydraulic oil cooler, radiator and fan shroud, do not damage the cooler core or the radiator core. |
21. Using two persons, put the hydraulic oil cooler, radiator and fan shroud, as a unit, in position on the front engine mount. Tilt the unit away from the engine to allow installation of the fan assembly.
22. Install the fan assembly and the six bolts that hold it.
23. Tilt the hydraulic oil cooler, radiator and fan shroud to a vertical position. Install the two shock mount rings, washers and locknuts (14) that hold the unit in position. Do not tighten the locknuts at this time.
24. Check the clearance between the fan blades and the fan shroud. The distance between the components should be approximately the same all around the fan shroud. Once the unit is correctly centered, tighten locknuts (14).
25. Check the condition of the o-ring seal in hydraulic hose (15). If the seal is worn or damaged, use a new part for replacement. Connect hydraulic hose (15).
26. Put hose (13) in its original position along the side of the radiator, and install the clip that holds it.
27. Check the condition of the o-ring seals in hoses (12). If the seals are worn or damaged, use new parts for replacement. Connect hoses (12) in their original locations under the operators platform.
28. Reinstall step (11).
29. Connect the upper hose (9) and the lower hose to the radiator.
30. Install the bolt, washer and locknut (8) that holds the radiator support in position.
31. Put two fan guards (7) in position around the fan assembly. Install one of the bolts that hold the two guards together. Rotate the two fan guards 180°. Install the other bolt that holds the two fan guards together. Put the fan guard assembly in its original position on the fan shroud, and install ten bolts (6) that hold it.
32. Reinstall access cover (5) on the operators platform.
33. Put the hydraulic lines, wiring harness and governor control cable in position in the bracket under the operators platform. Install socket head bolt (4) that holds them.
34. Put recovery tank (1) in its original position under the operators platform. Install the four washers and locknuts (3) that hold it. Connect three hoses (2) to the recovery tank.
35. Fill the cooling system with coolant and the hydraulic system with oil to the correct level. See the Operation & Maintenance Manual for the correct filling procedures.
