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

2
00:00:09,667 --> 00:00:21,167
<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
00:00:21,167 --> 00:00:25,542
Place the BS in the OFF position to prevent starting attempts.

4
00:00:25,542 --> 00:00:30,958
Also, place the FPB and the LCCB in the OFF position.

5
00:00:30,958 --> 00:00:34,792
Also, apply a warning tag on the EC switch.

6
00:00:34,792 --> 00:00:42,292
<b>Warning: </b>If the locomotive is equipped with AESS, the diesel engine may start without operator action.

7
00:00:42,292 --> 00:00:46,458
Exercise caution when working around the radiator cab.

8
00:00:46,458 --> 00:00:52,917
Ensure that AESS is disabled before performing any maintenance procedures on the locomotive.

9
00:00:52,917 --> 00:00:57,542
Failure to do so may result in death or serious personal injury.

10
00:00:57,542 --> 00:01:05,667
<b>Note: </b>This process can be performed while the air-based intercooler is installed in or removed from the locomotive.

11
00:01:05,667 --> 00:01:14,500
1. Remove the air-to-air shutter assembly as discussed in the Shutter Removal – Top-Mounted Shutter Assembly section of this module.

12
00:01:14,500 --> 00:01:19,417
2. Disconnect the grease fittings from the fan to be removed.
