Installing the Radiator
Diesel Engine: Service and Repairs
1. If the 2 straight hydraulic fittings (Item 2 in
the oil cooler, lubricate and install new O-rings onto the fittings. Install the
fittings into the port openings and tighten the fittings; refer to
Hydraulic Fittings (SAE Straight Thread O-Ring Fitting into the Component
Port) (page 4–11).
2. Carefully position the radiator and oil cooler assembly to the radiator frame.
Position the fan shroud to the radiator.
3. Secure the radiator to the radiator frame with the 7 flange-head screws
previously removed. Position the fan shroud to the radiator with the 7
fasteners previously removed. Ensure that at least 6.4 mm (0.250 inch)
clearance exists at all points between the fan shroud and the fan.
4. Position the coolant reservoir and reservoir bracket to the fan shroud.
Secure the reservoir bracket to the fan shroud and radiator frame with the 2
button-head screws (item 29 in
5. On the left side of the machine, secure the fan shroud to the radiator frame
with the 2 button-head screws (item 29 in
6. Remove the covers and plugs from the openings in the radiator and the oil
cooler and the disconnected coolant and hydraulic tubes that were installed
during removal.
7. Connect the hydraulic tubes to the straight hydraulic fittings
8. Connect the upper and lower radiator hoses to the radiator and secure the
hoses with the hose clamps. Torque the hose clamps to 3.4 to 4.5 N∙m
(30 to 40 in-lb).
9. Connect the reservoir hose (item 26 in
and secure the reservoir hose with the hose clamp.
10. Install and secure the air cleaner inlet hose; refer to
(page 3–10).
11. Ensure that the radiator draincock is closed.
12. To allow air to escape during radiator filling, remove the pipe plug (item 31 in
Figure 12) from the top of the radiator. Fill the reservoir with coolant.
Note: Ensure that the coolant level in the coolant reservoir is correct.
13. Apply thread sealant to the threads of the pipe plug.
Note: Ensure to install the plug once all air is bled from the radiator.
14. Install the pipe plug into the radiator opening.
15. Add hydraulic fluid to the hydraulic reservoir as necessary to raise the
hydraulic-fluid level to the operating range; refer to the Operator's Manual.
16. Start the engine and check for coolant and hydraulic fluid leaks. Repair any
leaks as required before returning the machine to service.
17. Continue to run the engine to obtain the operating temperature. Check the
coolant and hydraulic fluid levels and adjust as necessary.
18. Lower the hood and secure it with the latches.
19. Install and latch the screen (item 1 in
Figure
Figure 12) and 2 flange nuts.
