In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 4% 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 documents to determine the cause of fuel dilution.
Special Instruction, REHS3007,"Determining the Cause of Fuel Dilution of Engine Oil"
Troubleshooting, KENR9795, "C27 and C32 Engines for Caterpillar Built Machines"
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
5C0018195245 - 5C0018588683
6C001930907B - 6C002200848C
If an injector failure occurs on either of the rear two cylinders (right and/or left hand bank) the exhaust piping going from the turbo to the CEM will have to be removed. 346-0335 Exhaust Clamp cannot be reused and MUST be replaced with a new clamp. Refer to REHS5014, "Reuse Guideline for the Flexible Exhaust Pipe Group on Tier 4 Engines" for the proper installation and removal procedure. Refer to Image 2 for clamp location.
The 8S-9191 Injector Hold Down Bolts must be replaced.
Refer to Disassembly and Assembly, RENR9217 for the removal, installation, and tightening procedures.
After the engine is reassembled, change the engine oil and filters.
The refill capacities are per the Operation and Maintenance Manual.
