Possible Causes
How to Fix / Troubleshooting
Safety first: Do not place hands near moving parts while the unit is running. Shut down and allow to cool before tightening hardware.
- Inspect mounting bolts: Check that the engine and alternator mounting bolts to the base frame are tight.
- Examine isolation mounts: Look for cracked or collapsed rubber mounts under the engine/alternator assembly and replace if damaged.
- Tighten enclosure panels: Secure any loose access doors or panels that may be rattling.
If vibration remains severe, the rotor may be out of balance or the frame may be distorted, requiring professional service.
