Re: Flywheel removal 40 HP Evinrude

Thanks for the info guys! I’ll have to check just what grade bolts I have in my puller. A year ago I asked my local hardware store for the strongest bolts they had, but never checked what the grade was. When I know I have grade 8, I’ll tighten the puller more…..and I’ll try some heat too.

Just a thought – would it help to put an air impact wrench on the puller center bolt? Will that repetitive shock force help? It will solve the problem of the flywheel turning while I tighten it. I use the air impact wrench to loosen flywheel nuts, and it takes them right off without holding the flywheel.
