00:00:00,000 --> 00:00:08,292
There are two different generations of the air-to-air shutter assembly designs; a top-mounted design and a side-mounted design.

2
00:00:08,292 --> 00:00:13,083
The installation of a side-mounted shutter assembly is explained in this section.

3
00:00:13,083 --> 00:00:19,625
Typical steps to install a side-mounted shutter assembly to the air-based intercooler are as follows:

4
00:00:19,625 --> 00:00:30,917
<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
00:00:30,917 --> 00:00:35,000
Place the BS in the OFF position to prevent starting attempts.

6
00:00:35,000 --> 00:00:39,917
Also, place the FPB and the LCCB in the OFF position.

7
00:00:39,917 --> 00:00:43,708
Also, apply a warning tag on the EC switch.

8
00:00:43,708 --> 00:00:51,542
<b>Warning: </b>If the locomotive is equipped with AESS, the diesel engine may start without operator action.

9
00:00:51,542 --> 00:00:55,917
Exercise caution when working around the radiator cab.

10
00:00:55,917 --> 00:01:02,208
Ensure that AESS is disabled before performing any maintenance procedures on the locomotive.

11
00:01:02,208 --> 00:01:06,875
Failure to do so may result in death or serious personal injury.

12
00:01:06,875 --> 00:01:13,875
<b>Note: </b>Not all Evolution Series locomotives are equipped with the air-to-air shutter assembly.

13
00:01:13,875 --> 00:01:18,917
Some, in place of the air-to-air shutter assembly, have a covering grate.

14
00:01:18,917 --> 00:01:27,875
For these locomotives, remove all sets of clamps, lockwashers, washers, and bolts that secure the grate to the assembly.

15
00:01:27,875 --> 00:01:36,417
<b>Note: </b>The following steps are performed with the air-based intercooler removed from the locomotive and sitting on a support stand.

16
00:01:36,417 --> 00:01:45,250
<b>Warning: </b>All lifting fixtures and support stands referenced have been individually manufactured, tested, and certified.

17
00:01:45,250 --> 00:01:56,542
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
00:01:56,542 --> 00:02:01,500
Follow all Railroad Operating Procedures concerning lifting devices.

19
00:02:01,500 --> 00:02:10,417
<b>Warning: </b>The air-to-air shutter assembly weighs approximately 225 lbs. (102 kg).

20
00:02:10,417 --> 00:02:20,375
With the lifting device connected to the swivel clevis lifting lugs, ensure the lifting device is adequately supporting the assembly weight before removing the remaining hardware.

21
00:02:20,375 --> 00:02:24,417
Failure to do so may result in personal injury or death.

22
00:02:24,417 --> 00:02:32,042
1. Attach the lifting lugs to the shutter assembly and place the shutter assembly on the air-based intercooler frame.

23
00:02:32,042 --> 00:02:42,750
2. Install the four ½-13 x 1.25 inch hex bolts, ½ split lockwashers, and ½ flatwashers retained during removal.

24
00:02:42,750 --> 00:02:58,167
3. Install the ten ½-13 x 1.50 inch hex bolts, ½ split lockwashers, and ½ flatwashers retained during removal securing the air-to-air shutter assembly to the top of the air-based intercooler frame.

25
00:02:58,167 --> 00:03:05,458
4. If required, connect the air lines attached to the shutter cylinders on both shutter assemblies.
