Detector 72 #1 Posted October 25, 2016 I need some ideas on removing my muffler, it looks pretty bad. I got the clamp loose but the muffler where it slides on is brittle and flakes away easy, I used a small chisel and a jeweler hammer and with one light tap it chipped as you can see in the photo. I talked with the guys at POR-15 today and decided to go with their brush on high temp coating, the rep recommended sand blasting and hand sanding as a last option for best results, I may have to go with the last option unless you guys have some tips.

DennisThornton 4,769 #2 Posted October 25, 2016 Bigger hammer? Oxy/Acet torch? Just get after it with your hammer and chisel and spread the split area. You mean to remove it, repaint and reinstall? I've missed something? 1 Share this post Link to post Share on other sites
Detector 72 #3 Posted October 25, 2016 That's the issue, I lightly hit it under the split area and its chipping instead of spreading open. Sorry but yes I meant remove, sandblast, paint, reinstall.... Share this post Link to post Share on other sites

312Hydro 474 #6 Posted October 26, 2016 (edited) Do a search on E-tank rust removal or just rust removal and it will come up. Members have had good results with electrolysis, even freeing up rusted c-clamps. It will only remove rust. I assumed you had it off the engine,sorry. You could also spray penetrant and use heat as others have suggested.If you could get the elbow and muffler off together I would try the E-tank.

Detector 72 #7 Posted October 26, 2016 I may soak it with PB blaster again which did free up the rusty clamp bolts which kept me from cutting it off, it's a eye sore considering how the rest of the tractor looks so far into my restoration. Now that you mention it the E-tank would be less aggressive than my sandblaster which would likely blow through the thin areas. If all fails I'll have to sand it where it is the best I can and apply the POR 15. Share this post Link to post Share on other sites
DennisThornton 4,769 #8 Posted October 26, 2016 Sandblaster or electrolysis it will look rust pitted even after painted... If sandblasting blows through you had very little time left anyway. 1 Share this post Link to post Share on other sites

I looked under my model number 31-12KE01 and could not locate it for the M12 on Partstree but I may had overlooked it, I think it is a Toro 94-3739 same as the 312-8 with a hefty price of over $200.

DennisThornton 4,769 #10 Posted October 27, 2016 Maybe some high temp "ceramic" miracle in a can will buy you some time. Hey, I'm frugal! I cut a 1 pound tank down to fix a high price Simplicity muffler. It just worked out that what was bad was local and the same shape as the tank. Worked great and I expect years of use. BTW: http://www.cerakotehightemp.com/ Never used them but I've seen samples. Share this post Link to post Share on other sites
DennisThornton 4,769 #11 Posted October 28, 2016 Might try: POR 15 BVH Black Velvet HIGH-HEAT 1 Share this post Link to post Share on other sites

The guy with the welding shop said he's heat it up but wasn't comfortable being so close to the head so I may just sand/wire brush/degrease & coat it with the POR-15. I used the regular POR-15 on other projects and it's tough stuff actually the toughest I've seen yet but pricey 1 Share this post Link to post Share on other sites

6wheeler 633 #14 Posted November 1, 2016 (edited) Just sayin'. The muffler on my C-160 was junk. Toro wanted $275.00 for the replacement. Plus, shipping, $ 12.00. Elbo? $3.50 at ACE Hardware. Lead pipe $18.00 at Fleet Farm. IH tractor Muffler $ 26.00 at Fleet Farm. Bought a raincap for $9.00 at Fleet Farm just cuz it is cool. Got a "stack" for $ 56.50. It looks sweet too. Only saved $230.50 but hey? BTW, I rounded up. All Prices included MN. sales tax.Why not. Good Luck. Pat Edited November 1, 2016 by 6wheeler Share this post Link to post Share on other sites
