ONAN Marquis Gold 7000 Gas

The rubber coupler is bolted to the engines flywheel
and drives the serpentine style belt that drives the rotor in the generator.

The couplers break, belts sometimes break but usually more if they are oil soaked. Oil leaks are pretty common on these units. Oil collects in the plastic cover under the upper tray. Belt gets oily and comes apart.

It’s a pretty big job taking it all apart but I do them pretty regularly.

I know every nut, bolt, wire and everything else in most all Onans.

I have various specialty home made tools to do them and always have the parts on the shelf for fast turnaround.

You found the trouble so at least you know what you have to do now to fix it.
