Generator vibrates excessively during operation, causing enclosure to rattle

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Damaged engine mounts, Imbalanced fan or alternator, Misalignment between engine and alternator, Loose mounting bolts

Safety first: Keep clear of moving parts and do not place tools or objects on the generator while running.

Inspect mounts: With the engine off, check rubber engine/alternator mounts for cracks or separation. Replace if deteriorated.
Check base bolts: Ensure the generator skid is securely bolted to the foundation.
Look for loose components: Tighten loose panels, brackets, and exhaust supports that may amplify vibration.
Alignment check (advanced): For sets with flexible couplings, have alignment checked by a technician.
