KNOB 0377388 - Caterpillar

Test Procedure
Filter 100 ml (3.4 oz) of kerosene through a filter patch to ensure cleanliness of the solvent using the filtering procedure described in Tool Operating Manual, NEHS0729, "Use of Portable Contamination Control Kit". Caterpillar recommends using the 0.45 micron filter patch with the portable contamination kit. Using the 5 micron patch that is included in the kit is acceptable. Each oil sample to be analyzed will be split into two separate samples. Each sample will require 50 ml (1.7 oz) of filtered kerosene.Note: The best way to filter the kerosene is to use a 0.45 micron patch. The patches can be ordered through Fisher Scientific. The Fisher Scientific part number is 09-905-15 for a pack of 100. If the 0.45 micron patch clogs, filter the kerosene with a 5 micron patch, followed by a 0.45 micron patch. If the clogging issue is due to water, try a different container of kerosene and start over.
Fill two of the clean oil sample bottles to the top "Fill Range Line" with the oil to be tested. One sample will be tested without pretreatment and one will be tested with the pretreatment oil method. All the sample bottles should be rinsed with the oil that is being tested. Refer to Caterpillars Channel 1 for Tips and Tricks videos, along with Training Video, PERV4638, "Caterpillar Oil Sampling...The Right Way"Note: The source of the oil needs agitated, if possible, before the oil is sampled. For example, 3.78 L (1 US gal) and 18.9 L (5 US gal) containers should be shaken for 3 to 5 minutes before a sample is taken.
Shake one of the samples vigorously for 1 minute to ensure proper agitation of the oil.
Take the shaken sample and unscrew the lid one quarter of a turn. Place the bottle in the ultra sonic bath for 45 seconds to remove the air bubbles. Air bubbles remaining at the surface of the oil is acceptable.Note: The ultra sonic bath should be filled with enough water to cover 75-80% of the height of the bottle to allow the air bubbles to rise to the top of the bottle.
Remove the sample bottle from the ultra sonic bath. Analyze the oil sample using the particle counter per the manufacturer instructions to obtain the particle count results. This sample will be used as a reference to determine if additive interference is present in the oil.Note: As a reminder, the three code readout represents the counts for the 4, 6, and 14 micron size particles respectively. For new oil, only look at the values for the second and third codes. These codes represent the values for the 6 micron and the 14 micron size particles.
Take a third clean sample bottle and mark the 50 ml (1.7 oz) and 100 ml (3.4 oz) levels on the bottle. See the example below.
