Radiator Fan Removal

2
00:00:02,125 --> 00:00:08,208
1. Remove and save the eight bolts that hold the large screen on the left side of the radiator cab.

3
00:00:08,208 --> 00:00:12,917
2. Carefully, remove the large cab screen assembly and set it aside.

4
00:00:12,917 --> 00:00:19,750
3. Disconnect the three lead wires from the terminal block located on the underside of the radiator fan motor.

5
00:00:19,750 --> 00:00:29,000
4. Note carefully the identification of the lead on each terminal for subsequent reassembly, then install the hardware back on the terminal block studs.

6
00:00:29,000 --> 00:00:37,750
5. Remove and save the two bolts holding the two halves of the fiberglass radiator fan shroud together at the front and rear of the shroud.

7
00:00:37,750 --> 00:00:47,292
6. Remove and save the eight bolts holding the shroud half and metal pan to the cover plate on the side from which the radiator fan and motor are to be removed.

8
00:00:47,292 --> 00:00:50,458
7. Set the shroud half and metal pan aside.

9
00:00:50,458 --> 00:00:59,333
8. Remove and save the two long bolts holding the radiator fan and motor and the radiator fan support to the radiator cab structure.

10
00:00:59,333 --> 00:01:09,875
9. With a forklift or a lifting fixture suspended from a crane, reach into the side of the radiator cab structure through the opening from where the screens and shroud were removed.

11
00:01:09,875 --> 00:01:15,792
10. Insert the forks into the two hollow box sections across the bottom of the radiator fan motor.

12
00:01:15,792 --> 00:01:23,458
11. If using a crane and lifting fixture, switch the crane hook from the empty lifting location to the loaded lifting location.

13
00:01:23,458 --> 00:01:26,917
12. Remove and save the two remaining mounting bolts.

14
00:01:26,917 --> 00:01:31,167
13. Lift the radiator fan and motor and remove it from the side of the cab.

15
00:01:31,167 --> 00:01:41,417
14. Set the fan and motor down on wooden blocks; ensure that enough clearance exists under the motor to protect the terminal block and the bottom bearing cap.

16
00:01:41,417 --> 00:01:43,833
Radiator Fan Installation

17
00:01:43,833 --> 00:01:53,458
1. Place the forks of a forklift or a lifting fixture suspended from a crane into the two hollow box sections across the bottom of the radiator fan motor.

18
00:01:53,458 --> 00:02:01,917
2. Lift the fan and motor, and insert it through the opening from where the screens and shroud were removed in the side of the radiator cab structure.

19
00:02:01,917 --> 00:02:09,708
3. Lower the motor onto the support, aligning the fan and support with the mounting bolt holes in the radiator cab structure.

20
00:02:09,708 --> 00:02:19,417
4. Carefully remove the forks from the radiator fan motor box sections, preventing the radiator fan and motor or radiator fan support from shifting position.

21
00:02:19,417 --> 00:02:30,208
5. Install the four long mounting bolts with a lockwasher under each head through the radiator fan motor box sections and the radiator fan support into the radiator cab structure.

22
00:02:30,208 --> 00:02:40,292
6. Torque the four bolts to 440-490 lb.-ft. (597-665 Nm).

23
00:02:40,292 --> 00:02:46,583
7. Ensure that the fan tips have clearance around the shroud; if they do not, adjust as necessary.

24
00:02:46,583 --> 00:02:48,250
8. Rotate the fan.

25
00:02:48,250 --> 00:02:52,750
The fan motor must rotate freely with no rubbing sounds.

26
00:02:52,750 --> 00:03:02,333
9. Install the shroud half and metal pan on the side from which the radiator fan and motor was installed, and bolt it to the cover plate with the eight bolts.

27
00:03:02,333 --> 00:03:12,292
10. Install the two bolts holding the two halves of the fiberglass radiator fan shroud together at the front and the rear of the shroud, then tighten all ten bolts.

28
00:03:12,292 --> 00:03:24,417
11. Connect the three lead wires on the terminal block located on the underside of the radiator fan motor, ensuring that each lead is on the correct terminal, then tighten the nuts on the terminal block studs.

29
00:03:24,417 --> 00:03:28,667
12. Install the large screen on the left side of the radiator cab.

30
00:03:28,667 --> 00:03:33,292
13. Install and tighten the eight bolts to hold the screen in place.
