Subject: [alt-beam] Re: BGM motors
There sould be a white plastic deal an a gear with a spring on it. it's
a clutch. It lets the motor slip if too much force is against it. You
ought to be able to just pop that off. Look around for screws. that'll
pull the large metal portion off. If you want to keep the large metal
piece (and I can see why, since it's actualy something to mount the
motor with), you can use a knife or thin screwdriver to pop off a
plastic ring arround the top of each gear. you'll have to hacksaw the
posts off if you need those removed.
