[Jukebox-list] RE: Advice before I take apart AMI G transfer motor.

[Mechanical Music of S.F.]

OK, thanks for the info on the motor, John.
I don't want to screw it up, but looks pretty simple.  Almost 100% sure it's 
just gunked up.

I stupidly tried to turn the flat head screw on the scan motor thinking it 
was just an access for oil.  It turned a few degrees, but I put it back 
where it was when it became obvious it wasn't going to move freely.  Now I 
know better. Thanks.

Nope, never heard of that jukebox place.  I moved here in 2000.  There 
doesn't seem to be a lot going on jukebox wise around here.

Don't need to loosen the set screw or slot head large bolt - that
presets the tension on the armature and adjustment is normally only
done when a new armature is installed.

I would take the motor completely apart and take care to soak the
bearings in a good grade of oil. Clean between the plates on the
armature commutator with a very thin metal strip - I use a pinball
burnishing tool - to remove any carbon dust from the brushes. A piece
of spring steel would work well.

High pressure grease for the gear drive. Remove the brushes before
attempting to take the main bolts out of the motor is advised...

PS, ever hear of Judith's Jukes from San Francisco in the 1970s and
early 80s? They restored classic wood jukeboxes...
