Generator Framework Noises

I’m hoping that someone out there has had this experience before and can help me understand what might be going on. For the past year now, I’ve noticed that as we encounter small bumps in rest area pullouts, camp grounds, or any other place where the road surface isn’t as smooth as it could be, that the generator framework that supports the generator makes clunking noises. It sounds much as if one of the shock absorbers is loose, but I’ve had them checked several times and that’s not it. I suspect that the heavy duty rollers on the framework that holds the generator up are loose. In just the last week while traveling through New Mexico and Colorado along Interstate 25 the mysterious noise has gotten much more prevalent, and, the front cover that meets the front cap of our motorhome is now dropped down on the passenger side by about ¼”. This is not good. So can anyone who has had this sort of thing happen on their motorhome or knows what might be going on give me some guidance? I’d certainly appreciate it.

Thanks,
Rick
  • ON my Monaco coach, I had to weld additional braces under the generator because the lightweight steel used at the factory developed a crack. Just go underneath the coach and see what the brace looks like. Mine only had one cross member and i added two cross members. No problems anymore with the generator mounting.
  • I would indeed first check the framework and bracing for any broken welds and/or cracks. Do this sooner than later before your genset hits the road! (Literally!)

    Exactly. It definitely sounds like a broken weld to me. It should mimic the sound of a loose shock on a 4 cylinder car when you hit a bump.
  • Thank you rgatijnet1, mtrumpet and crasster for your valuable input. I will pull the genset out and have a look to see if I've lost a brace (which is what I suspect at this point) OR need additional bracing. I'll try and remember to get back into this post and let the three of you know what I found out and did about the issue. Thanks for your guidance and help.
