PROBLEM
Older 352-6378 and 20R-2919 Turbochargers have an interference condition at the cartridge to compressor housing joint that can reduce the service life of the clamp and/or the turbocharger.
Clamp failures are most common between 4000 and 7000 service hours on the clamp.
This interference condition exists on 352-6378 and 20R-2919 turbochargers with serial numbers of RIM41565 and older.
Turbochargers with serial numbers of RIM41566 and newer do not have this interference condition.

In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 7% 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
Inspect turbocharger identification plates to determine if turbochargers are part of the population (RIM41565 and older) that has the interference condition.
Refer to Image 1 and Image 2 for guidance on turbocharger identification and determination of build date.
The turbocharger identification plate can be found on the top of the turbocharger cartridge near the oil supply. Use the process below to determine the build date of the turbocharger from the serial number. The example being used is RIM41565.
R = Build Year - 2014
I = Build Month - September
M = Facility Code
41565 = Sequence Number
If turbochargers have serial numbers of RIM41565 or older and existing 268-2960 v-band clamps have accumulated 4000 hours or more, replace the clamps. Refer to Images 3 and Image 4 for examples of clamp failure.
