00:00:00,000 --> 00:00:05,625
Typical steps to remove a Victaulic coupling on the cooling water system are as follows:

2
00:00:05,625 --> 00:00:16,750
<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
00:00:16,750 --> 00:00:21,125
Place the BS in the OFF position to prevent starting attempts.

4
00:00:21,125 --> 00:00:26,333
Also, place the FPB and the LCCB in the OFF position.

5
00:00:26,333 --> 00:00:30,042
Also, apply a warning tag on the EC switch.

6
00:00:30,042 --> 00:00:37,167
<b>Warning:</b> If the locomotive is equipped with AESS, the diesel engine may start without operator action.

7
00:00:37,167 --> 00:00:41,167
Exercise caution when working around the radiator cab.

8
00:00:41,167 --> 00:00:46,750
Ensure that AESS is disabled before performing any maintenance on the locomotive.

9
00:00:46,750 --> 00:00:51,667
Failure to do so may result in death or serious personal injury.

10
00:00:51,667 --> 00:01:08,583
<b>Note:</b> When replacing a leaking or defective Victaulic coupling, depending on the location of the leaking or defective coupling, it may be necessary to drain the cooling water system to ensure water is removed from the section of piping containing the leaking or defective coupling.

11
00:01:08,583 --> 00:01:19,083
1. If required, drain the cooling water system as discussed in the Draining the Cooling Water System and Taking Cooling Water Samples section of this module.

12
00:01:19,083 --> 00:01:32,917
2. After the water from the cooling water system is drained or the pipe from which the Victaulic coupling is to be removed is empty, remove the bolts and nuts that hold the coupling halves together and remove the coupling.

13
00:01:32,917 --> 00:01:41,167
3. While supporting the pipe with one hand, slide the gaskets (one on each end of the pipe) onto the removable pipe.

14
00:01:41,167 --> 00:01:49,583
<b>Note:</b> After the gaskets and the body of the coupling have cleared the fixed pipe, the pipe can be removed to allow gasket removal.

15
00:01:49,583 --> 00:01:53,375
4. Remove the gaskets from the pipe.

16
00:01:53,375 --> 00:01:57,542
5. Protect the pipe ends after disassembly.
