Problem
Some inconsistencies have been observed in the prefixes "MDN" and "HEN" bus support assembly. Specifically, some flat washers are got deformed when installed over slotted openings.To prevent potential hardware failures and to mitigate the risk of ingress of foreign materials into the generator barrel, all hardware connections need to be inspected. Any inconsistency found in the hardware connections need to be corrected.Solution
Caterpillar is aware of the problem, and is recommending the below rework procedure.For defects on components that belong to the package, the dealer must contact the Global Dealer Solutions Network (GDSN) at 1 309 636-8500 or by submitting a Service Request (SR) through PSCRM as outlined in Service Warranty Bulletin 3.19.
Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility.
Accidental engine starting can cause injury or death to personnel. To prevent accidental engine starting, turn the ignition switch to the OFF position and place a do-not operate tag at the ignition switch location. Apply proper lockout/tagout procedure.
Personal injury or death can result from high voltage.When power generation equipment must be in operation to make tests and/or adjustments, high voltage and current are present.Improper test equipment can fail and present a high voltage shock hazard to its user.Make sure the testing equipment is designed for and correctly operated for high voltage and current tests being made.When servicing or repairing electric power generation equipment:
Make sure the unit is off-line (disconnected from utility and/or other generators power service) , and either locked out or tagged DO NOT OPERATE.
Remove all fuses.
Make sure the generator engine is stopped.
Make sure all batteries are disconnected.
Make sure all capacitors are discharged.Failure to do so could result in personal injury or death. Make sure residual voltage in the rotor, stator and the generator is discharged.
