Generator exhaust
Generator exhaust , inside the compartment . I replaced the exhaust receiver pipe ( 2 1/4" O.D. , 2 " I.D. , gen pipe slides into it ) some time ago , now I have exhaust leaking into the coach . The problem is obvious , and of my own making . I didn't look at the old pipe closely enough , missed the packing that is pushed into the bead , assumed that the bead was to keep pipe from pushing through the panel . I machined a steel " donut " , welded it onto the end of the new pipe and that was it , Voila ! exhaust leak . The blower then supercharges the fumes into the cabin . 
 Has anyone developed another way to do the exhaust system with the slide out generator ?  I thought perhaps a flexible pipe or steel braided hose , but probably inviting more problems reinventing the wheel ! That said , I am looking at machining another piece with an internal receiver groove for the packing . Alternatively I could order a tool for beading and go with original style .
Question , looking for a source for the packing , wonder if anyone can steer me ? I have a request at Newell parts , not sure they would still have such a thing , so I am looking at options . 
I have shot myself in the foot so many times it's a miracle I can still walk !!

You might have success with this, apply it on the exhaust pipe where it will slide in an inch as you return the generator to travel position.

It looked something like this

I picked the reinforced version but plain old graphite valve packing might do the trick.

Appreciate the link , I had looked at that and you have helped me zero in. I'm making a diy bead roller , we'll see how it works out . Will post as it all develops .
Thanks for the replies !

I was just scrolling through the pictures of the 2000 model with salvage title , shown in the Coaches for Sale area . Just out of curiosity , not a player on buying . I noticed that the Onan 12.5 is a slide out , with exhaust exiting the roof . Wondering if that vintage has similar arrangement with the exhaust system in the compartment as the Classics .
