Termination Date
June 30, 2002Problem
Engines may need to be repaired due to cracked main bearing caps on certain 3508, 3512 and 3516 Engines used in off-highway trucks, track type tractors, hydraulic excavators and wheel loaders or generator set, industrial, marine, locomotive, marine auxiliary and vehicular applications. A process was omitted during the manufacturing of the cylinder block main caps on certain 3500 Engines. Because of the omitted process, the main cap may crack. This crack may be detected during a regular maintenance interval or in the worst case, the crack may not be detected until the engine fails.

Failure Identification:
The failure mode of a broken main cap can occur at any SMU. To identify a main bearing cap crack that qualifies for this program, the cap must have a crack similar to the cap in Illustration 1 below. The crack MUST initiate from the either fillet radius of the cap. The cap may only be cracked or may be broken in two pieces.
Main caps with cracks in any other position DO NOT qualify for the program.
