Hi folks

More collateral damage from bad engine mounts. The exhaust pipe was rubbing the edge of the opening in the engine cover making it eggish shaped. I'd guess it may be worn off about 1/8". Without resorting to soldering in a new piece what would be the best way to fill in the worn area? Bondo or long hair FG come to mind. Would bondo alone be strong enough?
Thanks

Are you meaning the green side panel? If so, I'd just remove more metal to return it to round again. Having it larger shouldn't look strange, and would prevent future rubbing should a mount give way later.

Yes, Dan, the green side panel. I don't really want to enlarge it. I don't know the history of this tractor but I straightened out a bunch of bent stuff and realigned the console so that now the tail pipe is nowhere near the edge of the hole. I don't think it would rub unless the engine was loose. There is maybe 1/2" clearance. There is a lip on the edge of the hole and I think I can reform it but woud the bondo alone be strong enough? It would have to stand vibration but no other forces.

I don't think Bondo would hold without a backer for long. Best to epoxy a backer plate on the inside, then fill over top with bondo, or even better...JB Weld. Gotta run...Josh just brought me a load of silage to pack.

Thanks Dan. I never thought of JBW. I guess those new larger silage pits must be hard to fill!
