There have been instances of issues with DEF pumps. After analysis, the cause of the issues has been found as contamination with hydrocarbons.Note: Diesel fuel is an example of a hydrocarbon.The DEF filter is equipped with a compensator located in the center of the filter assembly. If the compensator comes into contact with hydrocarbons, the compensator will swell and is designed to block the filter assembly and protect the DEF pump.Solution
The following procedure is designed to diagnose if the DEF pump has been contaminated with hydrocarbons.
Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility.
Ensure that the engine is stopped before any servicing or repair is performed. The Diesel Exhaust Fluid (DEF) system must have completed a proper shutdown. Service on the DEF pump prior to completion of a proper shutdown can result in DEF spray and spillage.
Do not turn off the battery disconnect switch until the indicator lamp has turned off. If the switch is turned off when the indicator lamp is illuminated, the Diesel Exhaust Fluid (DEF) system may not shut down properly. If the DEF system does not shut down properly, DEF could freeze and damage the pump and lines.
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, NENG2500, "Cat Dealer Service Tool Catalog" or
