PROBLEM
Show/hide table
The PT3, PT5 and PT6 Pin Assemblies may fail prematurely on certain 330D and 336D Excavators due to some variability in the depth of the pin surface hardness. Pin manufacturing and design improvements have been implemented to improve the life of the pins.
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
