00:00:00,000 --> 00:00:05,833
Typical steps to install a Victaulic coupling on the lubricating oil system are as follows: 

2
00:00:05,833 --> 00:00:18,042
<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
00:00:18,042 --> 00:00:22,458
Place the BS in the OFF position to prevent starting attempts. 

4
00:00:22,458 --> 00:00:31,750
Also, place the FPB, LCCB, and BCCB in the OFF position, and apply a warning tag on the EC switch. 

5
00:00:31,750 --> 00:00:39,333
<b>Warning: </b>If the locomotive is equipped with AESS, the diesel engine may start without operator action. 

6
00:00:39,333 --> 00:00:43,417
Exercise caution when working around the radiator cab. 

7
00:00:43,417 --> 00:00:49,208
Ensure that AESS is disabled before performing any maintenance on the locomotive. 

8
00:00:49,208 --> 00:00:54,125
Failure to do so may result in death or serious personal injury. 

9
00:00:54,125 --> 00:01:00,000
<b>Note: </b>Couplings used in the cooling water system have a seal made of EPDM rubber. 

10
00:01:00,000 --> 00:01:05,125
EPDM rubber is indicated by a green mark on the inside of the gasket. 

11
00:01:05,125 --> 00:01:09,125
Couplings used in the lubricating oil system have a seal. 

12
00:01:09,125 --> 00:01:13,583
Seals are indicated by a blue mark on the inside of the gasket. 

13
00:01:13,583 --> 00:01:19,625
Couplings used in the compressed air system are completely red and made from silicon gasket. 

14
00:01:19,625 --> 00:01:26,042
1. Inspect the gaskets for cuts, holes, or embedded foreign material. 

15
00:01:26,042 --> 00:01:29,667
2. Inspect the sealing surfaces of the pipe. 

16
00:01:29,667 --> 00:01:35,000
<b>Note: </b>Rough or non-machined surfaces do not indicate a defective pipe. 

17
00:01:35,000 --> 00:01:41,958
However, there must not be scratches or gouges that cross more than 50% of the sealing surface. 

18
00:01:41,958 --> 00:01:49,042
If scratches or gouges are present, use sandpaper or a fine file to dress the pipe surfaces. 

19
00:01:49,042 --> 00:01:55,250
If defects cannot be removed without excessive sanding, the pipe should be replaced. 

20
00:01:55,250 --> 00:02:01,625
3. Inspect the cleanliness of the pipe and ensure it is clean and free of debris. 

21
00:02:01,625 --> 00:02:07,792
<b>Note: </b>Coupling seals used in both oil and water systems should be thoroughly lubricated. 

22
00:02:07,792 --> 00:02:12,542
This prevents tearing or cutting the gasket when it is assembled. 

23
00:02:12,542 --> 00:02:20,250
4. Slide both gaskets onto the fixed end of the pipe ensuring that each gasket is flush with the end.
