Re: Advice for cutting a flywheel off

[jerry-ahrens]

quote WetWillie:

I couldn’t agree more about the quality of the OMC puller as compared with any other puller I’ve ever seen. The shouldered bolts are also excellent. However, I snapped those same bolts early on when I used an impact wrench. Thats why I turned to Fastenal to get me a set of shouldered bolts that were even stronger. It was one of those that I had to remove yesterday after it too snapped. Next step is to try heating the flywheel again as hot as I can. I figure I have nothing to lose at this point. I’ll cut my losses and list the motor on CL if I don’t succeed.

You mentioned that you snapped off one of the shoulder bolts? Were you using them with the OMC puller plate? That’s why I mentioned the part about being careful with the impact wrench.. if the flywheel doesn’t want to pop off after a hit or two with the impact, try a tap with a ball peen hammer centered directly on top off the puller shaft. Do this with tension on the puller.
I have Heli coiled the 3 bolt holes and stepped them up to 3/8 then using the good puller set up, it came right off. You may have to replace the flywheel after doing the Heli coil depending on how well the inserts are installed. If it were me, I would avoid trying to cut it off, as it will most likely ruin the crankshaft. Hope this may be of help!
