Unauthorized use of this document or the proprietary processes therein without permission may be violation of intellectual property law.This guideline enables dealers and customers to benefit from cost reductions which were made possible through an established Contamination Control Program. Fluids that are 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 available from Caterpillar to ensure that such changes and improvements are incorporated when applicable.For questions or additional information concerning this guideline, submit a form for feedback in the Service Information System. To address an urgent issue, use the following resources to communicate your request to Caterpillar Repair Process Engineering:

This guideline enables dealers and wheel tractor scraper customers to benefit from cleaner transmissions. The kidney loop filtration process is easy to use. The kidney loop cart quickly connects to the transmission drain and transmission oil fill tube.This guideline provides directions for installing and operating the kidney loop system.Clean fluids play a major role in the life of any fluid system. The following procedure will help reduce fluid contamination in wheel tractor scraper transmission oils to an acceptable ISO cleanliness level. This procedure may be modified by the technician for use on some machines.The following procedure is for wheel tractor scrapers NOT equipped with ecology drain valves. The procedure is most effective when performed immediately after the oil has been warmed to 50° C (122° F) and the oil is mixed from operation. This action causes contamination in the system to be placed in suspension in the oil and lowers the oil viscosity.
If the vehicle system is being serviced due to a catastrophic component failure, a complete system cleaning operation is required. When system cleaning is complete initiate this kidney loop 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. Additional component cleaning, component exchange, and lines flushing will be required to remove most contaminates generated from the failure. The vehicle system cleaning MUST be performed prior to kidney looping. This filtration procedure and subsequent particle count testing should be performed as a final step in the repair process.
Important Safety Information
Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. A person must be alert to potential hazards. This person should also have the necessary training, skills, and tools to perform these functions properly.Improper operation, lubrication, maintenance, or repair of this product is dangerous. Improper methods could result in injury or death.Do not operate or perform any lubrication, maintenance, or repair of this product, until you understand the operation, lubrication, maintenance, and repair information. Safety precautions and warnings are provided in this manual and on the product. If these hazard warnings are not heeded, bodily injury or death could occur to you or to other persons.Hazards are identified by a safety alert symbol. Safety alert symbols are followed by a signal word such as "Warning" that is shown below.
Illustration 1 g01032906
The following is the meaning of this safety alert symbol:
Pay attention!
Become alert!
Your safety is involved.The message that appears under the warning explains the hazard. The message will be written or pictorially shown.Operations that may cause product damage are identified by "" labels on the product and in this publication.Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard. Therefore, the warnings in this publication and on the product are not all inclusive. If a tool, a procedure, a work method, or an operating technique that is not recommended by Caterpillar is used, ensure that the procedure is safe for all personnel around the machine. Also ensure that the product will not be damaged or be made unsafe by the operation, lubrication, maintenance, or repair procedures.All of the information, specifications, and illustrations that are in this publication are based on information that was available at the time of publication. The following could change at any time: specifications, torque, pressures, measurement, adjustments, illustrations and other items. These changes can affect the service that is given to the product. Obtain the most current and complete information before you start any job. Caterpillar dealers have the most current information that is available.Safety
Sudden movement of the machine or release of oil under pressure can cause injury to persons on or near the machine.To prevent possible injury, perform the procedure that follows before testing and adjusting the steering system.
Personal injury can result from hydraulic oil pressure and hot oil.Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system.Make sure all of the attachments have been lowered, oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.
