Information:
This Program can be administered aftera failure occurs. The decision whether to apply the Program is made bythe dealer. When reporting the repair, use "PS50440" as the Part numberand "7755" as the Group Number and use 135579 DTF Code. Use "96" as theWarranty Claim Description Code and use "Z" as the SIMS Description Code. The information supplied in this serviceletter may not be valid after the termination date of this program. Donot perform the work outlined in this Service Letter after the terminationdate without first contacting your Caterpillar product analyst. Dealer and District are responsible fordetermining eligibility. Engine installations that are known to have airentry into fuel supply are not eligible for this program.TERMINATION DATE
