In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 3% 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
1. Isolate the generator set before commencing any work on the unit, open generator set breaker, activate Emergency Stop, disconnect the battery cables and either disconnect or open the control circuit breaker for the AC power supply to the battery charger. Ensure all health and safety requirements are adhered to at all times. Also, ensure proper Lock Out-Tag Out procedures are followed at all times while work is being performed on the machine. Lock out generator operation and disconnect/lockout all power sources before commencing any work.
2. If there is evidence that the exciter rotor is loose, remove generator. Refer to Disassembly and Assembly, KENR5284 for SR5 disassembly and assembly instructions. The symptoms of a loose exciter rotor may include the following conditions: damaged main rotor lead cables and/or lugs, excessive vibration, abnormal noise.
3. Send generator to a qualified generator repair (rewind) shop with the capability to repair the main rotor shaft and to balance the entire rotor assembly.
