Just a little airplane reference there... I was told once there is no such thing as a generator on a airplane. True or false ?
While doing generator fluid checks I cycled old reliable on and off. To my surprise the air compressor mounted on the top of the generator jumped up and down as the generator shut down. Checking the mounting bolts (4) they were all turnable with my fingers.
With a rubber cushion block in-between mount tower and the generator base pretty much absorbs the vibration and noise when the air compressor cycles on and off.
The four nuts and bolts needed to be just tightened slightly to draw them a little tighter and cushioned on the pads as intended. Nuts are nylon self locking and are unlikely to come loose. It appeared the rubber pads had just over time decreased in thickness.
Just a couple of turns drawing up the bolts solved the excessive jumping around.
If you find this same situation don't over tighten as the cushion will be compressed and should be snug and just a half turn more.
