In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 1% 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
This program applies only for insufficient tube clearance which may result in a crack failure on the double-upset of the 8N-9706 Tube, or wear on face of 8N-9706 Tube (Image 1). If there is a different failure mode, for example, corrosion, or wear on the tube circumference (Image 2), then this program does not apply. If there is a crack failure on the double-upset of the 8N-9706 Tube, or wear on face of 8N-9706 Tube, then replace the 8N-9706 Tube with a shorter 475-4256 Tube. Replace the 8N-9609 Flange with a longer 475-4255 Flange. Refer the engine's Operation and Maintenance Manual, and Disassembly and Assembly, UENR0181. |
