Information contained in this document is considered Caterpillar: Confidential Yellow.

Information contained in this document is considered Caterpillar: Confidential Yellow.

This guideline enables dealers and customers to benefit from cost reductions which were made possible through an established Contamination Control Program. Fluids used in Caterpillar machines are highly effective unless the fluid contains damaging amounts of contaminates. Therefore, every effort must be made to reduce the contamination level within Caterpillar fluid systems. Caterpillar makes ongoing changes and improvements to the Caterpillar products. This guideline must be used with the latest technical information that is available from Caterpillar. Updated technical information will ensure that such changes and improvements are incorporated when applicable.

For technical questions when using this document, work with your Dealer Technical Communicator (TC).

To report suspected errors, inaccuracies, or suggestions regarding the document, submit a form for feedback in the Service Information System (SIS Web) Interface.

If a Contamination Control Guideline is required, but not available in SIS Web, submit a feedback form in the Service Information System website.

Canceled Part Numbers and Replaced Part Numbers

This document may include canceled part numbers and replaced part numbers. Use NPR on SIS for information about canceled part numbers and replaced part numbers. NPR will provide the current part numbers for replaced parts.

Summary

This guideline will enable dealers and customers to change the lubricating oil in the following fluid systems: engine, hydraulic, transmission, final drive, and differentials. Refer to the Operation and Maintenance Manual for the correct model-specific oil changing procedure.

Clean fluids play a major function in the life of any fluid system. The filtration procedure will help reduce fluid contamination in the oil to an acceptable level of ISO 16/13 or cleaner.

Note: If the machine is being serviced due to a catastrophic failure, a complete system cleaning operation is required before initializing this filtration procedure. If the failure is not addressed early, particles from the failed component will contaminate other system components such as valves, pumps, motors, and controls. Extra component cleaning, component exchange, and lines flushing will be required to remove most contaminates generated from the failure. The machine system cleaning must be performed prior to the filtration procedure. This filtration procedure and subsequent particle count testing should be performed as part of the repair process.
