Re: Flywheel removal 40 HP Evinrude

[David Stanton]

I got my OMC puller in the mail last week and tried it yesterday. It worked great! I put in the bolts and put my air impact wrench on the center bolt. The compressor had only pumped up to about 50 pounds, but in a few seconds I had the flywheel off! it’s amazing what the right tools can do. I messed around with the Harbor Freight bolt puller for two weeks.
As I suspected, this 1961 40 HP Lark had original coils, and most of you know what they looked like. I replaced them today and now have spark.
Thanks for the tip on the OMC puller.

FYI: My first bolt puller, I made myself when I was 14 in 1961 form scrap metal Dad had laying around to get the flywheel off my 1953 Champion 8.4 HP model 4LHD Hydro-Drive motor that I ran on a hydroplane I had just built. I’d never even seen a bolt puller, but just figured out what it had to look like to get the flywheel off. I used two slabs of 1/8 inch steel.
