I was removing the brush holder, dropped a screw. I would have thought the screw would have stuck to one of the magnets The motor was spinning freely before this happened. now it is not spinning. A quarter turn is as far as it goes. I have the motor stripped of everything I can remove. Snap ring removed.
Along with dust/lint I found three small nuts m4/5 on top of the magnets. The brush holder has a broken positive post which I could replace now that the brush holder is off the motor. The brushes and commutator look good.
Found the screw lodged between the magnet/case of the motor and the rotor windings.I will need to remove the rotor to remove the screw and check for damaged insulation. would a three jaw puller work or would I need to get it pressed out?

I took it into an electric motor service and rewinding place they Pressed the rotor out removed the screw screw pressed the rotor back in while I waited for $20. I replaced the broken positive post with a slightly smaller diameter brass machine screw 1/4" dia. vs .306". Largest I could find locally (didn't search too hard.). I may put in new brushes at which time I will put in a M8 post either copper or brass. I was mildly surprised when I hooked a 12v jumper box to the motor and it worked.
The three small holes are threaed but much smaller than 1/4" maybe m3/m4.
