Removing the Radiator (continued)
• The lower radiator hose (item 7 in Figure 12 ) that is connected to the
engine block.
• The coolant hose (item 28 in Figure 12 ) that is connected to the overflow
tank.
6. Align a drain pan under the 90° hydraulic fitting of the oil cooler.
7. Disconnect the upper and lower hydraulic tubes (items 33 and 11 in Figure
12 ) from the 90° hydraulic fittings in the oil cooler.
8. Remove the (2 each) 90° hydraulic fittings from the oil cooler.
9. Remove the 2 bolts (item 2 in Figure 12 ) and 2 flange nuts that attach the
cooling bracket to the radiator frame, and remove the cooling bracket.
10. Remove the top shroud (item 44 in Figure 12 ) from the machine.
11. Remove the bottom shroud fasteners from the radiator.
12. Move the shroud away from the radiator to allow oil cooler and radiator to be
removed from the machine.
13. Carefully remove the oil cooler and radiator from the machine.
14. Cover or plug the oil cooler, radiator, and the disconnected coolant and
hydraulic hoses to prevent contamination.
15. If necessary, separate the oil cooler from the radiator ( Figure 13 ).
16. Check the condition of the rubber isolator mounts (item 4 in Figure 12 ) and
replace the mounts if damaged.
17. Check the condition of the bulb seals (items 9 and 36 in Figure 12 ) and
replace the bulb seals if damaged.
Installing the Radiator
1. If removed, install the bottom shroud (item 42 in Figure 12 ).
2. If separated, assemble the radiator to the oil cooler ( Figure 13 ).
3. Remove the covers and plugs from the oil cooler, radiator, and the
disconnected coolant and hydraulic hoses that were installed during removal.
4. Carefully align the oil cooler and radiator with the radiator frame.
5. Install the top shroud (item 44 in Figure 12 ) to the radiator.
6. Ensure that equal clearance exists at all points between the fan shroud and
fan.
A. To move the fan shroud left or right, adjust the location of the radiator
in the radiator frame.
B. To move the fan shroud up or down, adjust the location of the shroud
on the radiator.
7. Install the cooling bracket (item 1 in Figure 12 ) to the radiator frame, press
the cooling bracket at the top with enough force to compress the bulb seal to
a maximum thickness of 6.35 mm (0.25 inch) before tightening the fasteners.
8. Connect the following hoses to the radiator:
• The upper radiator hose that is connected to the water pump.
• The lower radiator hose that is connected to the engine block.
• The coolant hose that is connected to the overflow tank.
9. Use new O-rings and lubricate the O-rings with clean hydraulic fluid before
installing the 90° hydraulic fittings.
10. Install the (2 each) 90° hydraulic fittings into the oil cooler.
