00:00:00,000 --> 00:00:08,625
There are two different generations of the air-to-air shutter assembly designs; a top-mounted design and a side-mounted design.

2
00:00:08,625 --> 00:00:13,625
The removal of the top-mounted shutter assembly is explained in this section.

3
00:00:13,625 --> 00:00:20,458
Typical steps to remove the top-mounted shutter assembly from the air-based intercooler are as follows:

4
00:00:20,458 --> 00:00:31,875
<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
00:00:31,875 --> 00:00:35,958
Place the BS in the OFF position to prevent starting attempts.

6
00:00:35,958 --> 00:00:40,792
Also, place the FPB and the LCCB in the OFF position.

7
00:00:40,792 --> 00:00:44,583
Also, apply a warning tag on the EC switch.

8
00:00:44,583 --> 00:00:52,417
<b>Warning: </b>If the locomotive is equipped with AESS, the diesel engine may start without operator action.

9
00:00:52,417 --> 00:00:56,792
Exercise caution when working around the radiator cab.

10
00:00:56,792 --> 00:01:03,083
Ensure that AESS is disabled before performing any maintenance procedures on the locomotive.

11
00:01:03,083 --> 00:01:07,750
Failure to do so may result in death or serious personal injury.

12
00:01:07,750 --> 00:01:14,875
<b>Note: </b>Not all Evolution Series locomotives are equipped with the air-to-air shutter assembly.

13
00:01:14,875 --> 00:01:20,042
Some, in place of the air-to-air shutter assembly, have a covering grate.

14
00:01:20,042 --> 00:01:29,083
For these locomotives, remove all sets of clamps, lockwashers, washers, and bolts that secure the grate to the assembly.

15
00:01:29,083 --> 00:01:37,625
<b>Note: </b>The following steps are performed with the air-based intercooler removed from the locomotive and sitting on a support stand.

16
00:01:37,625 --> 00:01:46,000
<b>Warning: </b>All lifting fixtures and support stands referenced have been individually manufactured, tested, and certified.

17
00:01:46,000 --> 00:01:57,458
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
00:01:57,458 --> 00:02:02,542
Follow all Railroad Operating Procedures concerning lifting devices.

19
00:02:02,542 --> 00:02:11,667
1. Remove and save the four bolts, washers, and lockwashers securing the actuator cover to the shutter assembly.

20
00:02:11,667 --> 00:02:17,667
2. Remove the shutter actuator cover to allow access to the air lines.

21
00:02:17,667 --> 00:02:22,833
3. Disconnect the air lines attached to the shutter cylinders.

22
00:02:22,833 --> 00:02:33,250
4. Remove and save the hex bolts, washers, and lockwashers securing the air-to-air shutter assembly to the top of the air-based intercooler frame.

23
00:02:33,250 --> 00:02:42,292
<b>Warning: </b>The air-to-air shutter assembly weighs approximately 273 lbs. (124 kg).

24
00:02:42,292 --> 00:02:45,125
Ensure the lifting device is adequate.

25
00:02:45,125 --> 00:02:49,417
Failure to do so may result in personal injury or death.

26
00:02:49,417 --> 00:02:56,083
5. Attach lifting lugs to the holes in all four corner gussets of the shutter assembly.

27
00:02:56,083 --> 00:03:02,292
6. Lift the shutter assembly from the top of the air-based intercooler frame.
