This guideline enables dealers and engine customers to attain the benefits of cleaner engines. The kidney loop filtration process is easy to use and will add only a small amount of extra time to your dyno testing. The kidney loop cart quickly connects to the engine oil ecology drain and engine oil fill tube. Most Caterpillar engines have the ecology drain so you will not need to install one.This guideline also provides you the information needed to modify the filter cart and provides directions for installing and operating the kidney loop system. The kidney loop procedure is used with the engine dyno test and particle counting process. This procedure will remove many of the break-in particles that are in the engine. The engine roll-off target is 18/15 or better for rebuilt engines. Clean fluids play a major role in the life of any fluid system. The following procedure will help reduce fluid contamination in Wheel Loader Transmission oils to an acceptable ISO cleanliness level.Important Safety Information

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.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, PERJ1017, "Dealer Service Tool Catalog" for tools and supplies
