1. If removed, install the fan shroud and ensure that the equal clearance exists
between the fan and the top and bottom of the fan shroud.
2. If separated, assemble the radiator to the oil cooler as follows:
A. If the hydraulic fittings were removed from the oil cooler, lubricate and
install new O-rings to the fittings. Install the fittings into the oil cooler
ports (Figure 10).
B. Attach the oil cooler to the radiator with the 4 screws (item 4 in
8 flat washers, 4 lock washers, and 4 hex nuts.
C. Install the radiator and oil cooler assembly to the machine.
D. Check that the gap between the oil cooler and radiator is less than 2.3
mm (0.090 inch). If the gap is more than 2.3 mm (0.090 inch), fill the gap
with silicone sealer to ensure effective sealing.
3. Remove the covers and plugs from the opening in 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 radiator support (item 1 in
the radiator support 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.
6. Carefully position the fan shroud to the radiator. Secure the fan shroud to the
frame as shown in
7. 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. Ensure that
the hose clamp on the lower radiator hose does not contact the alternator
belt.
• The coolant hose that is connected to the coolant reservoir assembly.
8. Use new O-rings and lubricate the O-rings before installing the hydraulic
fittings to the oil cooler.
9. Connect the upper hydraulic hose to the straight hydraulic fitting and lower
hydraulic hose to the 45° hydraulic fitting in the oil cooler.
10. Apply thread sealant to the threads of the pipe plug (item 8 in
Install the plug into the radiator opening.
11. Check that no gaps exist between the radiator, the radiator frame, and the
machine frame.
12. Fill the radiator with the appropriate coolant; refer to the Operator's Manual
for coolant specifications.
Note: Ensure that the coolant level in the coolant reservoir is correct.
13. Install the radiator cap (item 2 in
14. Add hydraulic fluid to the hydraulic reservoir as needed to raise the
hydraulic-fluid level to the operating range; refer to the Operator's Manual.
15. Start the engine and check for coolant and hydraulic fluid leaks. Repair any
leaks as required before returning the machine to service.
16. Continue to run the engine to obtain the operating temperature. Check the
coolant and hydraulic fluid levels and adjust as necessary.
17. Lower the hood and secure it with the latches.
