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.
