Typical steps to install an air-to-air fan assembly for locomotives with a top-mounted air-to-air shutter assembly to the locomotive cooling system are as follows:

2
00:00:10,000 --> 00:00:21,500
<b>Warning: </b>To prevent personal injury and potential equipment damage, ensure that the engine cannot be started before removing, installing, or adjusting any engine component.

3
00:00:21,500 --> 00:00:25,875
Place the BS in the OFF position to prevent starting attempts.

4
00:00:25,875 --> 00:00:31,292
Also, place the FPB and the LCCB in the OFF position.

5
00:00:31,292 --> 00:00:35,125
Also, apply a warning tag on the EC switch.

6
00:00:35,125 --> 00:00:42,625
<b>Warning: </b>If the locomotive is equipped with AESS, the diesel engine may start without operator action.

7
00:00:42,625 --> 00:00:46,792
Exercise caution when working around the radiator cab.

8
00:00:46,792 --> 00:00:53,250
Ensure that AESS is disabled before performing any maintenance procedures on the locomotive.

9
00:00:53,250 --> 00:00:57,875
Failure to do so may result in death or serious personal injury.

10
00:00:57,875 --> 00:01:04,625
<b>Note: </b>This process can be performed while the air-based intercooler is installed in the locomotive.

11
00:01:04,625 --> 00:01:12,125
<b>Warning: </b>The air-to-air fan assembly weighs approximately 300 lbs. (136 kg).

12
00:01:12,125 --> 00:01:14,875
Ensure the lifting device is adequate.

13
00:01:14,875 --> 00:01:19,000
Failure to do so may result in personal injury or death.

14
00:01:19,000 --> 00:01:25,458
1. Attach a crane or lifting device to the lifting hooks on the air-to-air fan assembly.

15
00:01:25,458 --> 00:01:31,542
2. Install the air-to-air fan assembly in position on the air-to-air intercooler.

16
00:01:31,542 --> 00:01:39,875
3. Install all bolts and washers retained during removal to secure the air-to-air fan assembly to the air-to-air intercooler.

17
00:01:39,875 --> 00:01:43,458
4. Connect all fan motor leads.

18
00:01:43,458 --> 00:01:46,375
5. Connect the grease fittings.

19
00:01:46,375 --> 00:01:55,625
6. Install the air-to-air shutter assembly as discussed in the Shutter Installation – Top-Mounted Shutter Assembly section of this module.
