If the locomotive is not equipped with an oil sampling valve or quick-disconnect, an alternative method of collection is the use of a suction-type device to extract oil through the oil fill pipe while the engine is shut down. 

2
00:00:13,792 --> 00:00:17,458
The suction device should be fitted with clean tubing. 

3
00:00:17,458 --> 00:00:27,708
The length of the tube should be sufficient to allow the sample to be extracted from the mid-level of the oil, not from the bottom of the oil pan or from the top surface of the oil. 

4
00:00:27,708 --> 00:00:34,250
If possible, the oil sample should be collected within 15 minutes after shutting down the engine. 

5
00:00:34,250 --> 00:00:39,375
<b>Note: </b>Be careful not to overstroke the plunger when using the suction device. 

6
00:00:39,375 --> 00:00:46,292
This causes oil to enter the pump and leads to cross-contamination of future oil samples.
