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?

18 is the largest i have and it just fall through
no thread gauge
must be for pto flywheel
