The aluminum shell is held in place by screws around the periphery of the
shell.  The shell may be a little snug, but it will come off!  The notched
ring is a retainer that attaches the motor to the gearbox.  It screws out
counter-clockwise and you can remove it by tapping firmly with a cold
chisel.  A machinist friend fabricated a special tool for me that that
slips over the motor and matches the notches perfectly.  It makes the job
a little easier, but I used only a cold chisel and hammer for many years
before that!  You may need to loosen this ring if the aluminum shell is
binding against it, but the ring is not intended to retain the shell, only
the motor.  After you have removed the retaining ring, the motor will pull
straight out of the gearbox.

73!
