Mudrig150 344 #1 Posted October 14, 2019 So I have to remove the muffler elbow on my K241 to put the correct muffler on my tractor. It's still intact, and I don't want to break it off because we don't have a thin enough hacksaw to cut it. Been soaking it in PB blaster and tapping the block lightly for a while now. Any other suggestions? Share this post Link to post Share on other sites
Blackhood Bill 722 #2 Posted October 14, 2019 You might try running till hot, then spray wd40 around the threads. This in turn will cool and suck in the lubricant into the threads. 1 Share this post Link to post Share on other sites

Blackhood Bill 722 #4 Posted October 14, 2019 You can also try heating with a small torch and then spray. Same effect different heating method. 1 Share this post Link to post Share on other sites
ebinmaine 73,681 #5 Posted October 14, 2019 I agree with Bill as stated above. Heat. Penetrating oil. Repeat. Patience. Just as a point of interest I am not at all a fan of PB blaster. I've had very very poor success with that product as a penetrating oil. This is the kind of subject where a lot of people have their favorite thing to use and many of them work quite well. I'm a huge fan of Kroil in the spray can and believe it or not good old-fashioned $6 a can Liquid Wrench. Share this post Link to post Share on other sites
peter lena 9,349 #6 Posted October 14, 2019 mechanical advantage is best, using a 14" pipe wrench , tighten it to stop at about 11 oclock toward steering wheel , using a 3 lb hammer , hit the area just behind the barrel nut adjuster on wrench, that is your hardest reverse impact, you should not have any wrench bounce, just a solid drive impact. that should do it, along with a penetrating oil, pete Share this post Link to post Share on other sites
pfrederi 18,810 #7 Posted October 14, 2019 Air chisel with a blunt point. You are not trying to cut it just vibrate the heck out of it. Work all around it then focus on the left hand side I walked one out that way not long ago. 1 Share this post Link to post Share on other sites
