Re: Two stuck flywheels

[chris-p]

quote Mr. Asa:

Last one I had that was a PITA I tightened the puller as much as possible, smacked the side of the flywheel with a wooden mallet a couple times, rotated it 90 degrees, tightened as much as possible and hit it, kept doing that. Eventually it popped.
By the end I was having to use my electric 1/2″ impact to tighten the central pulling bolt.

Hit the side of the flywheel, don’t hit the top. The vibrations from the impact are what you want.

Also, the majority of other pullers that people are going to use are likely to be automotive designed. Way overbuilt for what you’ll normally see in outboards usage. I doubt you’ll see any deflection in them. There can be a problem with the bolt size not fitting in the slots for the automotive style pullers, but that’s easily fixed.

Actually, don’t hit the side of the flywheel either, nor the top. Just the puller bolt.
