My compressor seems to be louder and vibrates more since I rebuilt it last week. The only change other than a major rebuild is that I added a washer to each of the four mounting bolts so that now the compressor 's mounting plate is held firmly between the bolt heads and the rubber pads. When I removed the bolts originally a couple of them weren't tight to the plate but were bottomed-out in the threaded insert inside the rubber pad. Now everything is tight, but seems like the counter balance isn't performing correctly.
I realize those four rubber pads allow a lot of "bounce to the ounce" but how much compressor vibration is normal?

hmm, I think compressor on mine sort of "floats" on the rubber mounts with the springs on the bolts - you may have yours cranked down too tight, unlikely it is your rebuild, more likely your re-install would be my guess.

Just lay it in there on foam or carpet. have done that with W/pumps before.
Do you mean deep-six the rubber pads and use foam or carpet with through-bolts instead? It's almost like the rubber pads are too long or too soft allowing too much movement, so the compressor really vibrates. Maybe limiting the amount of travel will be the fix, if I'm reading you right.
Bump for T-Man
On our Thomas compressor 2 of the 4 rubber mounts on ours were torn in half, replaced them with new
The rubber mounts do wear out.
The idea is to isolate the compressor vibration from the rest of the coach, not necessarily keep it from vibrating.
That said, IIRC the durometer of the OEM ones used doesn't necessarily match the harmonics of the compressor, either.
