MOPED ARMY

1 of 2 options to fix if it is the keyway in the center 1 you get a wad of rolling papers and wrap them around the crank then you take the best Loctite stuff you can find when you put it on make sure it's it's nice and flush and secure on the crank and crank it down as hard as you can make sure that the rolling papers and stuff don't get most out of the sides make sure everything is all tight in there then take a heat gun and heat it it should hold interior heated again with a torch but if it's really bad and that doesn't work for you you can get square keys from the hardware store and cut grooves in both the Hub and the crank that correspond you'll need to take it to a machinist but it would be immediate gratification then trying to hunt down and pay for a part
