00:00:00,000 --> 00:00:04,208
Typical steps to remove the coalescer hoses are as follows: 

2
00:00:04,208 --> 00:00:16,625
<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
00:00:16,625 --> 00:00:20,958
Place the BS in the OFF position to prevent starting attempts. 

4
00:00:20,958 --> 00:00:30,333
Also, place the FPB, LCCB, and BCCB in the OFF position, and apply a warning tag on the EC switch. 

5
00:00:30,333 --> 00:00:37,750
<b>Warning: </b>If the locomotive is equipped with AESS, the diesel engine may start without operator action. 

6
00:00:37,750 --> 00:00:41,875
Exercise caution when working around the radiator cab. 

7
00:00:41,875 --> 00:00:47,708
Ensure that AESS is disabled before performing any maintenance on the locomotive. 

8
00:00:47,708 --> 00:00:52,583
Failure to do so may result in death or serious personal injury. 

9
00:00:52,583 --> 00:01:01,583
<b>Note: </b>The coalescer has been designed to have no contact with the engine or the components except for the coalescer hose connections. 

10
00:01:01,583 --> 00:01:04,375
This decreases the chance for wear. 

11
00:01:04,375 --> 00:01:09,417
<b>Warning: </b>Do not remove the hoses while the engine is running or hot. 

12
00:01:09,417 --> 00:01:21,375
1. If removing the upper hose, remove the P-clamps and disconnect the steel braided boost hose from the eductor and the tee fitting in the turbocharger casing. 

13
00:01:21,375 --> 00:01:30,167
2. If replacing the hose, cut the tie-wraps that connect the steel braided boost hose to the coalescer hose. 

14
00:01:30,167 --> 00:01:40,833
3. Loosen the 9/16-inch (15-mm) clamp bolts that secure the ends of the upper and lower hoses to their attachment pipes. 

15
00:01:40,833 --> 00:01:52,625
4. Rotate the ends of the hoses back and forth at the attachment points just enough to break any bonding that may have occurred between the hose and the attachment pipe. 

16
00:01:52,625 --> 00:02:02,167
5. Pull the free ends of the hoses off the pipes, taking care not to scrape the hoses against other components that may damage them. 

17
00:02:02,167 --> 00:02:08,917
6. Cover the openings to the coalescer and both ends of the coalescer hoses. 

18
00:02:08,917 --> 00:02:20,208
<b>Note: </b>For the upper hose, an additional 3/4-inch (19-mm) bolt must be removed from the P-clamp that supports the hose near its center.
