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...
