Re: 50hp flywheel removal
....looks like a previous owner has put thread or bearing lock on the taper shaft (nice of them).....
I actually did this to a Johnson motor once :redface:
I had an old boat mech at a local shop work on the motor several times. Started with just setting points, but then it just kept shearing the woodruff key. After taking it back about 4 or 5 times he wanted to start charging me. Turns out there was a little filing of metal around the tapered crank end, so the flywheel was only being held by the woodruff key. After letting go so many times both the flywheel bore and the crank end were galled.
My fix? Cleaned up the points and set them carefully, cleaned up the crank and flywheel with emery cloth, and after seeing that it fit down onto the crank nicely again, I used two dots of blue loktite on the shaft before setting the flywheel into place.
:redface: Tapped it down with a wooden block while tightening the nut. I didn't use the boat much for a few years and sold the whole shebang. Sad but true but it never spun the flywheel on me again
I didn't think about it at the time but I pity the guy now who had to change the points next :redface: Probably cleaning the shaft was enough but I had been stranded on the water too many times at that point. When the flywheel spun it would mess up the ignition timing and sometimes it would wind up in a spot that just wouldn't fire the engine until it was fixed.
Anyway, I merely wanted to say make sure your flywheel bore and the crankshaft taper are clean of foreign metal and crap. Someone might have used loktite for a reason
