Parts Needed
4 - 3N1968 Shock Mount (except on generators with serial number prefixes 5UA, 5YA, 6NA and 6SA where 6 - 3N1968 Shock Mounts are required)
Action Required
If the generator is in service, disconnect all electrical power before proceeding with the repair. Remove the terminal box side panel to allow access to the regulator assembly. (Left side when facing the louvered intake end.) Inspect the 3N1968 Shock Mounts for the location of the parting line. See the illustration. (SEE ILLUSTRATION) If the shock mounts have a parting line that is closer to one end, replace the side panel and return the generator to service. If the shock mounts have a parting line that is in the middle, replace the mounts. Put 9S3263 Thread Lock on the threads of the mounts before the nuts are installed. Check the soldered joints of the wires at the back of the droop, gain and level control potentiometers. Repair any loose or broken connections.
