    It is just something that you are going to have to do battle with. You'll notice by looking at the new arm that the bushing is ridged and tapered. Tightening the nut presses it on, and it's not going to come off willingly. Basics:

    1) Penetrating oil to loosen the 'cold weld' effects of dissimilar metals pressed together.
    2) Grab whats left of the arm and wiggle it
    3) With a wood block wrapped in soft cloth to protect the glass and bodywork, get something underneath to very gently pry upward while wiggling the arm.

    With luck, it should eventually come loose.

    Use plenty of penetrating oil, loosely put the nut back on to protect the threads and use a pulley puller to break it free.

    I've never had one so stuck that a minor amt of what I suggested wouldn't break it free. TonyVir's suggestion is the next level up and the safest way to go. Too much yanking is liable to damage the motor gearbox output shaft or the seal. Inexpensive pullers can be purchased at a tool place Harbor Freight.

    Thanks for the input im still confused as to how i took it off, but after struggling for a while i went back out turned the motor on and then shut it off and just tapped down clockwise and the mechanism popped off. But i thank everyone that took the time to respond to my issue love this forum
