    Removing Couper from Crankshaft

    Hey, I was wondering if there is something special I have to do to remove the coupler(shown in the picture attached) from a slx780 crankshaft?? I found one small bolt on it and unscrewed it but it didnt do anything if anyone could help me out that would be great..

    Feed a rope into the spark plug hole on the PTO cylinder to prevent the crankshaft from turning and then put a big wrench on the coupler and remove.

    tried to take it off with the wrench but its not working..the cranks already had the whole top end removed so its just the shaft and the cases..

    Put something steel (ratchet, pipe, etc...) through the con rod hole. Then put a block of wood on either side for the steel to rest on top of. This will stop it from moving down any more while you're turning the wrench. Good luck
