Muffler issues

[jmenende]

Howdy gang! Got an issue with an mep 007b. The gasket that holds the muffler in place and stops it from rattling is gone. I found the gasket (71-4396) in the manual but its no where to be found online. Anyone have an idea on how to keep it centered?

If you can't find anything better, you might look for some thin wood stove gasket rope.

You can buy some high temp gasket material and just make up a gasket and have in large enough to grab the bolts. You could cut up some header wrap to make a good gasket.


Easy fix.

Thanks. I dont know if the gasket paper will hold up to the vibration over time. Maybe a muffler wrap or the stove rope will.

If it were me and rigging needed to be done, I would use a few wraps of exhaust pipe wrap.

I would figure out where your true center should be on this machine for the muffler placement, open the hole up in this plate, and install a large high temp grommet. Even if its not OEM, if you open the hole up, respective to center, the grommet will grab the thickness of the plate, and take up most of the difference.

Should be good enough for this application. Ideas: https://www.zoro.com/rubber-grommets/c/10291/

Im even thinking of centering it and just weld it in place. Fuggetaboutit.

Can you not just open the hole slightly and move on with life? Its for rain entry only really... if the hole is large enough the oscillation of the muffler will just not hit any sides.

The issue is that the muffler has an area that is flex piping. When that gasket goes, the flex pipe start rubbing against the genset chassis till it breaks. I have 3 of these units with the exact same problem.

Oh I see. Well maybe something outside of the box then... not sure what the OD of the muffler pipe is, but maybe a two piece flange that you can tighten correctly, then drill holes into the case for a final location?
