    657x crank problem

    former local dealer installed a crank in this 95 gtx
    customer pick it up put it in the water and the pto flywheel spins off and damages the threads of his new crank
    i sugest he take it back since they didnt torque it correctly
    he refused to take it back
    he brings it to me to repair
    does anyone know the size and pitch of the crank?
    he knows this is a patch but im hoping i can get him back in the water as cheap as possible
    this ski isnt really worth putting a new crank in let alone a 2nd new crank

    From what I remember, I think it is M18 x 1.5. I also had to chase the threads on crankshafts a couple of times.

    18 looks small when looking @ the tap
    gonna see if it will fit in the pto before running the die across the crank

    Oh, I just re-read your post. I thought you meant the MAG end where the flywheel is.

    Sorry, the PTO end is bigger, I don't know what the thread size is off hand.

    Do you have a caliper and thread pitch gauges?
