    Pto coupler removal? Standard thread or reverse thread ???

    So in order to replace the PTO seal I need to split the cases, as some have mentioned I'm already this far into it might as well do it for peace of mind and inspect the crankshaft etc. So does the crankshaft pto coupler spin to the left or to the right to remove it looking at the back of the engine? Thanks

    Regular thread. Lefty loosey looking at the back of the ski. Don't forget to move the rope to the rear cylinder. Opposite of what you did for the flywheel. That way you don't get all that twist running through the crank and possibly knock your crank out of phase.

    Right now I have a wrist pin through the back connecting rod wrist pin hole, and pulling against the deck of the block.. This mofo will not budge.. I have the heads off this engine..

    Sounds scary to me. Some people do the rope trick on the cylinders. I like to remove the head and put a 1 inch block of hardwood on top of the piston and put the head back on when removing the coupler. If I know the coupler needs to come off, its one of the first things I remove from a motor. They can be a real bear sometimes. A 3 foot pipe on your wrench makes it a lot easier.

    The rope in the cylinder trick is stressing the same points as the way I'm doing it.. It will not come loose.. Tighter then a mosquito puss. Haha

    Same concept as your speaking off only not pushing on the piston or cylinder/dome

    Did it work? I got the impression you were letting the pin hit directly on the cases. That looks ok to me.
