I have a Sears Model Number 113.197150 radial arm saw that is late
eighties/early nineties vintage. The blade jammed into a piece of wood
and now the motor hums, but does not spin when I turn it on. I have
replaced the capacitor, but no luck. I wanted to take the motor off
and have an electric motor shop take a look at it, but I can't figure
out how to disconnect the power cord from the arm. Do I need to take
the arm apart to get to the wire connections or do I try to take the
motor apart? I can't figure out how to take the arm apart to get to
the wires.

Does the motor shaft spin freely by hand? Will it start with a little
push?

More than likely you will need to take the wires out of the motor.
