jjs 0 #1 Posted January 8, 2014 good evening. Having some difficulty removing my flywheel and I am using a wheel puller. It appears there was red loctite used in the keyway, will ox Acetylene torch damage it? Thanks Share this post Link to post Share on other sites
rmaynard 14,932 #2 Posted January 8, 2014 (edited) I don't know why anyone would have used Loctite on the keyway. Before using heat, I would use the tried and true method of flywheel removal. Using the proper type of puller that screws into the threaded holes in the flywheel, tighten it up until you can't tighten it any more, then bang the end of the puller with a hammer. Chances are the flywheel will pop right off. Oh, by the way, Edited January 8, 2014 by rmaynard Share this post Link to post Share on other sites
pacer 3,160 #3 Posted January 8, 2014 It is hard to figure why loctite would be used on a key --- but... stranger things have happened! To answer your question, yes heat is the recommended method for loosening loctite, it doesnt take a lot. Maynards method of removal is indeed the best way to get it to turn loose. I suppose you could have some heat on the shaft while you have the puller attached and giving the sharp 'raps' They can be pretty darn stubborn in some instances, but most time this method works.

chazm 412 #4 Posted January 8, 2014 WELCOME TO Like Bob said ... use the correct puller and a BFH. I would use heat if the BFH fails to get it off. Chasm Share this post Link to post Share on other sites
jjs 0 #5 Posted January 11, 2014 thank you! Could not find the proper (plate type) puller, so i tried to make one. When I tried to find the proper size flywheel bolts, struck out. Too small, too big. Upon further inspection, looks like the flywheel bolt hole threads have been.....well lets say, damaged. Can I do a helicoil repair to cast iron, I believe the flywheel is cast iron. Or maybe I can braze carbon steel nuts to the wheel Share this post Link to post Share on other sites
pacer 3,160 #6 Posted January 11, 2014 The puller I use is called a steering wheel/harmonic balancer/flywheel puller - heres one on ebay, but you should be able to find one in a auto parts store. Its a tool handy to have in the shop for a lot of things. http://www.ebay.com/itm/2in1-Professional-Harmonic-Balance-Puller-Set-Tools-Steering-Wheel-Crankshaft-/291055120749?pt=Motors_Automotive_Tools&hash=item43c43cb16d&vxp=mtr The flywheel has 4 threaded holes and surely all 4 arent buggered, even if they are get a tap and run in them and clean em up. Welding cast iron for a novice is difficult - heh, its difficult any how. They are 3/8-16 coarse threads, one of the most common threads. Share this post Link to post Share on other sites
gregg'shorses 77 #7 Posted January 11, 2014 Better to stand to the side when giving a little persuasion with the hammer, as sometimes they come off with quite a kick. And maybe on the floor so it doesn't crack if it drops of the work bench. Share this post Link to post Share on other sites
Fordiesel69 226 #8 Posted January 13, 2014 4 holes, you will find two of the 4 are still usable. Tap them clean, thread the bolts in a far as they will go, and heat the flywheel, not the crankshaft. Share this post Link to post Share on other sites
TT-(Moderator) 1,128 #9 Posted January 13, 2014 Not every flywheel has four holes. Drilling and tapping the stripped holes to the next larger size would be the best solution if they are the only choice. Here's a little post I made quite a while ago: Here's a picture of one of my flywheel removal tools: Share this post Link to post Share on other sites
jjs 0 #10 Posted January 13, 2014 Gents, thanks for the help, I built a puller, the center stud sheared off under considerable torsion, I had some 4 letter words for it as my wife happened to visit in the garage, 10 seconds later, pop, it came off by itself!
