Hey guys, I'm rebuilding this yz I bought in boxes, and came to installing the primary drive onto the crankshaft. I think I found all the pieces, but the thrustwasher ends up sitting on a round section of the shaft, so you can move it up and down, and it's splines don't mate with the shaft's splines. Is that normal? I don't understand why they would use a thrustwasher for this if it's splines don't mate.
