PRIORITY - Product Improvement Program to inspect/repair fan drive bearing race on certain C32 fan drives.
MODELS INVOLVED - Certain C32 Generator Sets
Dear Caterpillar Product Owner:
On certain C32 generator sets, the bearing race for the front bearing in the fan drive may have been installed incorrectly. The generator set needs to be inspected for correct installation of the bearing race. If the bearing race has been installed incorrectly, the fan drive will have to be disassembled and the bearing reinstalled correctly. Failure to perform this operation may result in premature failure of the drive belts. 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 15Nov2006 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.
