Onan Generator Help

TimKGillespie · 04-06-2020, 05:00 PM

Well I'm your first then...belt is broken. Based on the way it suddenly quit, I suspected voltdr was probably right. Took the brush cover off and cranked it, fan did not spin. Reached in to the pulley on the generator input and there was no belt. I was able to feel around and grab the belt and remove it. Now I have the part number. Getting the back panel off and the belt on will be a treat in my coach...

Thanks for both your help...

Yes that’s a first.
It’s a pretty HD belt.
Check to make sure nothing dropped down in there and caused the failure.
On some machines the battery charging voltage regulator/rectifier is mounted above the belt. The mount breaks from vibration.

They are not fun to work on. Very compact units and very busy inside.

Just about every machine I repair in MH’s has to come out to fix. Very little access.

If you can fix it without pulling it out that’s a plus.
