Tom,
My Speeditwin was worse than that. I had to replace the flywheel, but I used my crank as is. Clean the burr’s off the crank and torque it down tight as Art said. I don’t know what the torque value is supposed to be. Probably 2 whacks on a wrench with a big hammer.
Running them loose is what causes this.
I had to make a new key from some key stock.
Have fun!
