MaineDad 85 #1 Posted October 18, 2010 I have broke one puller and have had this one on for two days now with no success! I have been soaking it with PB Blaster too. Any tricks? This puller is starting to bend :thumbs: Share this post Link to post Share on other sites
WH nut 553 #2 Posted October 18, 2010 Smack the puller bolt with a good hit, should pop right off Share this post Link to post Share on other sites
Horse'n Around 22 #3 Posted October 18, 2010 X2 what Rick said... make sure there is pressure on the puller and give the puller bolt a whack dead center. John Share this post Link to post Share on other sites
MaineDad 85 #4 Posted October 18, 2010 Well I bent puller#2 tonight. I gave it a couple good whacks with tension as instructed with no success. I crank the puller a little bit more and whacked it again. Nothing. Cranked on the puller and kurplunk - bent the thread screw. So I got out the torch and heated it real good for about 5 minutes then took a big bolt and whacked it again. Nothing. Any more ideas? Share this post Link to post Share on other sites

Polaris2007 4 #6 Posted October 19, 2010 Micah, If you go to the local Napa or Autozone, you can buy an automotive harmonic balancer puller. It will work on the Kohler flywheels, and it has a cast body that will not bend. Use the shortest bolts that you can to screw into the flywheel. This will keep the center bolt that you tighten as short as can be, and minimize it bending. I use that with a 1/2" impact gun. I haven't found a flywheel yet that will stand up to this method.

WH nut 553 #7 Posted October 19, 2010 If you have an air chisel, put a blunt bit in it and wrap around the hole while you have tension on it Share this post Link to post Share on other sites
MaineDad 85 #8 Posted October 19, 2010 I heated around the shaft with special attention to the keyway. Should I have done something else? I will go get a harmonic balancer puller today, if I can find one... Share this post Link to post Share on other sites
B-8074 19 #9 Posted October 19, 2010 Your local auto parts store should have it. As for appling heat, you don't want to apply direct heat to the crank shaft. Apply the heat to just one side of the fly wheel near the key way. Think of it as a clock with the key way at high noon. Apply heat from 11 to 2 , this will allow the flywheel to expand without to much affect to the crank. Focus the heat to the flywheel. You should see the moisture leaving the flywheel. I don't know what kind of torch you have. Cutting or plumbers, but either one will work. Just remember you want the flywheel to expand, not the crank shaft. The heat with the harmonic balancer puller, you should be good. If you have an impact gun for your compressor use it. The impact action will definetly help. Good luck and let us know how it turns out. Share this post Link to post Share on other sites
pfrederi 17,206 #10 Posted October 19, 2010 When you finally get it off , what with all the hammering and heating you may find that the magnets are loose and/or not very magnetic anymore Share this post Link to post Share on other sites
MaineDad 85 #11 Posted October 19, 2010 Found the puller at Napa. 12 bucks. Started using it and both the big threaded bolt and the crank is flattening as I crank it tighter. Walking a way for an hour to cool off! And yes the flywheel nut has been removed. Share this post Link to post Share on other sites

MaineDad 85 #13 Posted October 19, 2010 Broke the Napa Harmonic Balancer Puller too. The engine is in the vehicle and will be delivered to the machine shop with the flywheel on! I have removed several flywheels in the past, and this one beat the you-know-what out of me! Hopefully the machine shop can press it off. Share this post Link to post Share on other sites
stevasaurus 22,285 #14 Posted October 20, 2010 Micah...it ain't you buddy...they just don't make pullers like they used to. Hope that helps. :) Share this post Link to post Share on other sites
