    Oh, man, don't get me started! I spent 2 days trying to remove the coupler and change the rear seal. Actually, wound up changing all the seals once I got that far. Wound up holding the engine down with a floor jack and a post to the ceiling joist, and using a pipe wrench and a torch. Torch is ok if you're changing the seals anyway.

    Then, of course, it turns out the clown who last worked on my engine put the rear main seal in the wrong place. Rear seal has no metal lip. Genius put metal lip seal in back, and put the rear seal in the middle.

    Here's some pics of holding the motor still, and of the wrong seal in the rear of my SL750 motor:

    Stick a good nylon rope into the spark pulg hole and put a pipe wrench on the coupler.

    Be sure to put the rope at the PTO cylinder so you don't take the crank out of index and leave a little piece of rope sticking out so you can remove the rope after you crack the coupler loose.

    PTO=Pilot Take Off or the driveshaft end. If you put the rope in the magneto cylinder than you run the risk or twisting the crankshaft. Put the rope in the cylinder nearest the drive shaft.

    Wild. We've always called it the Power Take Off.
    For future reference if you ever have to remove the flywheel you will be at the other end of the engine (MAG) side so you will want the rope in the first cylinder.
    Always put the rope at the cylinder you're working at.
    Driveline=PTO cylinder=3
    Center=CEN=2
    Flywheel/Stator=MAG cylinder=1

    Me too, but it's my understanding that both are acceptable.
