How to Fix / Troubleshooting
Safety first: Do not place hands on vibrating components while running. Shut down and disconnect battery negative before tightening hardware.
Steps:
- Inspect mounts: Check the rubber engine and alternator mounts on the Gillette skid for cracks or separation. Replace any failed mounts.
- Check skid bolts: Ensure the generator skid is securely bolted to the concrete pad. Tighten anchor bolts.
- Coupling alignment: On units with a flexible coupling between engine and alternator, inspect for misalignment or damaged coupling elements. Realignment should be done by a technician.
- Balance issues: If vibration persists, the rotating assembly may be out of balance, requiring professional service.
