    1200 crank shaft

    How do you get the flange coupling off the crank shaft?

    If the engine is still together the only way I think you can get it off is with a coupler removal tool and a 1/2 inch impact. Otherwise you have to hold the flywheel end somehow. The coupler tool is fairly cheap online.

    are the threads standard or left handed?

    If the motors still together do the good old rope trick down the spark plug hole. Just make sure it doesn't go into the exhaust port. Then a big bar in the coupler and pull real hard. Heat will make it easier if it doesn't come without any

    I used a mallet and a flat pry bar about 2ft long.. place the flat pry bar between the coupling "teeth" and smack the upper end of the pry bar with the hammer.. after you put a rope in the cylinder of course.. 2 good smacks and my coupler practically spun itself off..

    I got it off. It was out of the engine, so I strapped the crank down so it couldn't be moved and used a long metal pipe in between the teeth of the coupler and it came right off.

    For the next person who stumbles upon this post...

    I did the rope trick and then put a harbor freight chain wrench around it with a socket wrench and my floor jack handle to raise the torque ratio.
