It has been years since I removed a motor from a Diamond Disc machine, in this case an A-100. Maybe when I see it in person it will be obvious, but if there is something I should be aware of, please let me know. I need to move the whole machine to work on the cabinet and the motor and do not want to damage anything.
Thanks!

Not too difficult. You'll probably remember when you start. First, remove the reproducer. Then remove the 3 motor plate mounting bolts, 2 on the right and one on the left. The bolts should have a lock washer and nut on the bottom. They may fall into the cabinet when you loosen them, you can pick them up after you remove the motor. Next, remove the mute ball assembly from the horn pivot bar. Loosen the set screw that secures the mute ball to the cable and remove the mute ball. Loosen the set screw that secures the cable to the mute ball mounting bar and remove the cable. Last, loosen the 2 each ¼" square nuts that secure the horn pivot bar to the lifter handle. Hold the pivot bar and twist the lift handle back and forth to loosen it then lift the motor to disengage the pivot bar. The motor should lift right out.
Piece of cake...

Thanks, Cliff! I think I can handle it now!
I did not want to break that pivot rod.
