'82 310 bath exhaust blade source
Im rebuilding the bath exhaust fan in my 310. Got it apart, kind of, and it looks like the squirrel cage type plastic fan blade is shot. Does anyone have a parts source for this blade? Ive got a new motor to go in but need the blade?

Thanks folks,

Mike spencer

Found a Nutone replacement "blower wheel" on Amazon that is 1/4" smaller in diaameter but correct 1/4" shank. It should do the trick. I tried VTS, Inland, and Silver Trailer Supply and they said they had no replacement.

Google Image Result for

5" dia.x 1 1/4" deep 1/4" shank, hope it works

Hey dave,
If you need the motor too, ive got a used one that i pulled out of one of the stock exhaust vents above the rear bed. It was working just fine when i pulled it. They are about $65 new i think. Like i said it was working fine, i just replaced with Maxxair vent fans, its yours for the asking. (Free that is) just let me know and ill get it to you.

Ventline Vanair Trailer Roof Vent w/ 12V Fan - 6-1/4" Diameter - Smoke Ventline Enclosed Trailer Parts VP-543SP

This place has a direct replacement for that exhaust fan. I put 2 new ones in my coach

I would replace the whole unit. All the parts and plastic top degrade over time...

Well since i had a brand new motor on hand from another fan i decided to go ahead and repair rather than replace. That nutone blade from the link in my previous post came today and it ended up being an exact replacement. Got it put back together and works as it should. So Wxbouy if you decide to repair yours, thats the blade you need. The spring steel arms that raise and lower the cover are tricky to get back together.

Thanks! Will probably go with new since everything else will be new but will check the above link for replacements when I get home. Not to mention I probably wont get to it till next spring when I redo the shower.....

Replacing the fan unit
It's about time to replace this fan after 28 years of trusty service. My roof-top inspection suggests that removal will require grinding away some spot rivets that hold the motor and bracket to the circular base plate, which is itself held on the roof by sheet metal screws. Has anyone any experience of this? Ideally I would source the metal base plate as well, but this does not seem to come with the replacement fan assembly.

I replaced both of my fans with the Ventline fans and everything needed came with the fans

Thank you for your prompt reply. The photo in your link does not show the steel extra base plate to which the steel motor brackets are welded in my 1988 Excella. Does the fan in the photo secure direct to the roof skin of the trailer?

My guess is that the replacement unit exchanges a plastic ring for the steel ring on my trailer, so I've ordered the unit. Thanks again.
