In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 2% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.
ACTION REQUIRED
If excessive fuel dilution of engine oil is found reference the following to determine the cause of fuel dilution.
Refer to Special Instruction, REHS3007, "Determining the Cause of Fuel Dilution of Engine Oil"
Troubleshooting C27 and C32 Engines:
UENR0505 C27 Petroleum Generator Set Engines
UENR0504 C27 and C32 Industrial Engines

Once an injector(s) has been identified as having a cracked/leaking injector body, replace the failed injector(s). Inspect the remaining good injector serial numbers with Cat ET, (Injector Serial Numbers = Injector trim file name, (ie 6Cxxxxxxxxxx.trm)). If the remaining injector serial numbers fall within the serial number range below, replace at the same time. Refer to Image 1 for the serial number location on the top of the electronic unit injector.
Injector Serial Numbers
6C001793971D through 6C002198297C
8S-9191 Injector Hold Down Bolt must be replaced.
Refer to Disassembly and Assembly, KENR8167 for the removal, installation, and tightening procedures.
After the engine is reassembled, change the engine oil and filters.
