PRIORITY - PRODUCT IMPROVEMENT PROGRAM FOR REPLACING P-FRAME CIRCUIT BREAKER SUPPORTS
MODELS INVOLVED - Certain C32 and 3500 Generator Sets
Dear Caterpillar Product Owner:
Existing supports for the P-frame circuit breaker are too thick and prevent proper thread engagement on the nuts. New supports with counter bored holes need to be installed on the products listed below. You will not be charged for the service performed.
Contact your local Caterpillar dealer immediately to schedule this service. The dealer will advise you of the time required to complete this service.
Please refer the dealer to their Service Letter dated 03Jan2007 when scheduling this service.
We regret the inconvenience this may cause you, but urge you to have this service performed as soon as possible to prevent unscheduled downtime.
