Re: flywheel ***,y
OK, time to take the time to tell how to make your own knocker. The deep nut is one way, but here is how I do it. Go to the hardware store and get yourself two nuts and a short bolt, shorter the better, same thread as the shaft. I think it is 7/16 NF.
Run one nut up on the bolt, then the second one only a turn or two. Then run the first nut back down against the second one and jam them together. You have just made yourself a special tool.
To use, screw the knocker onto the shaft, hand tight. Using a screwdriver, pry lightly upward on the flywheel, just a tad, enough to raise it up in the bearing. Now use a hammer to give the knocker a sharp rap or two. That flywheel will pop right off, no problem. No magic potions or heat required.
Notice I said a sharp rap with the hammer. I did not say murder it with a sledge. It is the shock that knocks it loose, not the bash. And don't pry on it with a crowbar. All it takes is a lift.
I have used this method on a bazillion small motors, including lawn mowers and chainsaws, have never damaged one yet. The knocker puts the shock on the end of the shaft, not on the threads.
