Johnson A Flywheel Removal

[adam1961]

I thought there was a thread on the right way to pull a flywheel off of an early Johnson Model A, but I can’t seem to find it.
I have tried a few sharp taps with a brass hammer over the flywheel nut (loosened) wile supporting the flywheel. No luck yet. Is there another method that works well?

I don’t have a link to that thread but someone here told me about the flywheel knocker- bolt with 2 nuts tightened down on the flywheel threads and it worked great when I took mine off. I’m at the shop now without my camera or i’d take a pic of it for you. Very simple but works great for the model A and more.Did you try looking on you tube for Doug Penns video on removing a flywheel? I think that one shows you the flywheel knocker also.

Yes bolt with 2 nuts on it, same thread as the crank threads.

Thread one nut one deep. Thread second nut on, so that half of its threads are on bolt, the other half open to air. Then tighten the first nut down back onto the second one to lock it in place.

then thread this tool onto the crank, slightly pry upwards on the flywheel, then give the bolt head a few sharp raps. Should pop free.

I did this on my A35, and it worked. The screw holes in the flywheel looked to small to use my regular puller.

The most ingenious device I have seen was a steel ring with three countersunk holes corresponding to the holes in the rope plate on the Johnson. The Johnson flywheel screws are an odd size, no longer available. This ring also has three Quarter twenty holes to which a standard puller may be bolted. So, screwing this ring on the flywheel in place of the rope sheave gives you a place to attach a flywheel puller. The flywheel comes off with no damage to the crankshaft. It was what George Cheatum at Michigan Marine sales used on his old Johnsons.

before you knock itwith a hammer if you do nat have someone to lift up on the flywheel get some wood shims like used to install a door and lift the flywheel with the shims then knock down on the crankshaft worked great on my handitwin

A "Boathouse Repair" is one that done without having tools or the skills to do it properly.

Tubs, thanks for the suggestion. I used your method on my last couple of motor just used shims to hold fly wheel up sinceI did not have an extra set of hands works great
