PRIORITY - PRODUCT IMPROVEMENT PROGRAM FOR REWORKING DRIVELINE ON CERTAIN C-18 GENERATOR SETS WITH LC6 GENERATORS
MODELS INVOLVED - CERTAIN C-18 GENERATOR SETS WITH LC6 GENERATORS
Dear Caterpillar Product Owner:
The driveline needs to be reworked on certain C-18 generator sets. Six shims were inserted between the flex plates and the hub of the generators resulting in zero crankshaft endplay. This could result in engine and generator bearing failure. 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 31Oct2006 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.
