*excessive* vibration
Posted: Wed Mar 26, 2014 11:10 am
When I bought my '90 van, I was told that the generator had excessive vibration. "You wouldn't be able to sit on the couch while it's running". They weren't kidding!
Noise level isn't the issue - the entire cabin shakes, almost violently. Run it for 5 mins and your feet will vibrate for 15 afterwards.
It's mounted in the compartment with "L" brackets on each side, and one bolt is missing - assumed this might be the issue and planned to replace that and put some sort of pad underneath to help absorb the vibration. I showed a home-mechanic friend of mine, and he was wondering about the mount of the motor inside the generator - felt that it may be loose and moving around too much inside the gennie case causing the vibration.
I pulled the gen out and I see there are 3 large bolts underneath that mount the motor inside. These bolts all have small squares of plywood as a spacer between the head of the bolt and the case - all plywood is loose, meaning all bolts aren't fully snug(?) From what I can see the bolts go through the plywood, then the casing, some rubber bushings, then the mount.
Anyone have any experience/advice with this?!?
