Portable Particle Analyzer Procedure
When using a Portable Particle Analyzer for particle counting, be sure to read and understand the Tool Operating Manual before operating.

Attach the fabricated particle counter low pressure in suction tube to the S O S valve (12) on the filter cart. Refer to Illustration 7.Note: The fabricated suction tube can be made with the parts listed in the Table 3 Optional Tools chart and as shown in Illustration 7.Note: When using a 188-0645 Particle Analyzer Gp , the European style minimess fitting must be replaced with a 220-8608 Fitting Group to allow for the suction tube connection.
Attach the other end of the fabricated suction tube to the low pressure in port on the portable particle counter as called for in the Tool Operating Manual.Note: Information regarding the availability of parts and fabrication instructions for the suction tube assembly can be obtained by contacting the Caterpillar Service Technology Group Hotline. Proper fittings and instructions will be provided at no charge. A 188-0639 Hose As will need to be purchased prior to assembly.Bottle Sample Procedure
Illustration 8 g02398780
Bottle procedure(12) S O S valve(13) 169-8373 Bottle Group
If collecting a bottle sample, use the same S O S valve (12) and a 169-8373 Fluid Sampling Bottle (13). Refer to Illustration 8.
Record an oil sample from the S O S valve (12) on the filter cart at the beginning of the filter cycle. Refer to Illustration 8.Note: Kidney loop filtration can be performed while running the engine.
Operate the filter cart until the portable particle analyzer indicates that the oil has reached an ISO level of at least 18/15. The final ISO should be recorded before the machine is returned to the field.
Disconnect the filter cart suction and return hoses.
Exercise the machine for 2-3 minutes.
Reconnect the filter cart suction and return hoses.
At the halfway point of kidney looping, stop the procedure and change the machine filters.Note: Changing the machine hydraulic filters half way through the filtering process avoids opening the filter housing after the system has been cleaned. If the filter housing is opened after the filtration process is complete, the opening becomes an inlet for contamination. The new filters can remain in place until the next scheduled filter change.
When the target ISO level or time interval has been met, close air supply valve (8) and disconnect air supply hose (7). Refer to Illustration 6.Note: Refer to Oil Compartment Filtration Times, located at the end of this document, when a portable particle analyzer is not available.
Disconnect filter cart discharge from return port (6) on the fill cap adapter (2). Install the dust caps on the coupler and nipple. Refer to Illustration 5.
Disconnect filter cart suction hose from suction port (5) on the fill cap adapter (2). Install the dust caps on the coupler and nipple. Refer to Illustration 5.
Remove 193-5903 Fill Cap Adapter (3). Store in a clean location.
Install the strainer and lock
