00:00:00,000 --> 00:00:04,458
Typical steps to drain the air compressor oil are as follows:

2
00:00:04,458 --> 00:00:10,792
1. Place the LCCB in the OFF position to prevent the air compressor from running.

3
00:00:10,792 --> 00:00:18,167
2. Place a receptacle of sufficient capacity under the air compressor drain pipe to collect the oil.

4
00:00:18,167 --> 00:00:28,125
<b>Note: </b>The WABCO Model 3CDCLAT air compressor has a lubricating oil capacity of 16 gallons (60.56 liters).

5
00:00:28,125 --> 00:00:33,583
The drain pipe is located on the Helper’s side of the locomotive under the platform.

6
00:00:33,583 --> 00:00:46,083
3. Open the two drain valves — one located near the base of the air compressor on the Helper’s side, which should be tagged open, and the other located under the platform on the Helper’s side of the locomotive.

7
00:00:46,083 --> 00:00:51,667
<b>Caution:</b> When changing the air compressor oil, thoroughly clean the crankcase.

8
00:00:51,667 --> 00:01:00,125
Any dirt and sludge remaining in the crankcase could be picked up by the pump and, if allowed to accumulate, could eventually plug the pump suction.

9
00:01:00,125 --> 00:01:08,708
If such blockage occurs, the flow of lubricating oil will be obstructed, resulting in possible damage to the compressor’s moving parts.

10
00:01:08,708 --> 00:01:16,000
4. Wipe the air compressor crankcase using a railroad-approved solvent and clean, lint-free cloth.

11
00:01:16,000 --> 00:01:22,875
5. Close the drain valve near the base of the air compressor and the drain valve under the platform.
