00:00:00,000 --> 00:00:08,208
There are two different generations of the air-to-air shutter assembly designs; a top-mounted design and a side-mounted design.

2
00:00:08,208 --> 00:00:13,042
The installation of the top-mounted shutter assembly is explained in this section.

3
00:00:13,042 --> 00:00:20,000
Typical steps to install the top-mounted shutter assembly from the air-based intercooler are as follows:

4
00:00:20,000 --> 00:00:31,417
<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.

5
00:00:31,417 --> 00:00:35,500
Place the BS in the OFF position to prevent starting attempts.

6
00:00:35,500 --> 00:00:40,333
Also, place the FPB and the LCCB in the OFF position.

7
00:00:40,333 --> 00:00:44,125
Also, apply a warning tag on the EC switch.

8
00:00:44,125 --> 00:00:51,958
<b>Warning: </b>If the locomotive is equipped with AESS, the diesel engine may start without operator action.

9
00:00:51,958 --> 00:00:56,333
Exercise caution when working around the radiator cab.

10
00:00:56,333 --> 00:01:02,625
Ensure that AESS is disabled before performing any maintenance procedures on the locomotive.

11
00:01:02,625 --> 00:01:07,292
Failure to do so may result in death or serious personal injury.

12
00:01:07,292 --> 00:01:14,417
<b>Note: </b>Not all Evolution Series locomotives are equipped with the air-to-air shutter assembly.

13
00:01:14,417 --> 00:01:19,583
Some, in place of the air-to-air shutter assembly, have a covering grate.

14
00:01:19,583 --> 00:01:28,625
For these locomotives, remove all sets of clamps, lockwashers, washers, and bolts that secure the grate to the assembly.

15
00:01:28,625 --> 00:01:37,167
<b>Note: </b>The following steps are performed with the air-based intercooler removed from the locomotive and sitting on a support stand.

16
00:01:37,167 --> 00:01:45,542
<b>Warning: </b>All lifting fixtures and support stands referenced have been individually manufactured, tested, and certified.

17
00:01:45,542 --> 00:01:57,000
Lifting devices manufactured by other facilities per these recommended numbers should be individually tested and certified by an appropriate outside testing agency before use.

18
00:01:57,000 --> 00:02:02,083
Follow all Railroad Operating Procedures concerning lifting devices.

19
00:02:02,083 --> 00:02:08,875
1. Attach the lifting lugs to the holes in all four corner gussets of the shutter assembly.

20
00:02:08,875 --> 00:02:14,417
2. Place the air-to-air shutter assembly on the top of the air-to-air frame.

21
00:02:14,417 --> 00:02:20,917
3. Install the hex bolts, washers, and lockwashers retained during its removal.

22
00:02:20,917 --> 00:02:25,000
4. Connect the air lines to the shutter cylinders.

23
00:02:25,000 --> 00:02:29,500
5. Place the shutter actuator cover on the air-to-air frame.

24
00:02:29,500 --> 00:02:37,375
6. Install the four bolts, washers, and lockwashers to secure the shutter actuator cover.
