I saw his thread on the NTC board and followed his instructions while I took apart the maxi alti last night. The only thing i was concerned about was the rust on the inside of the stator. The brushes were fine (the inside one was a little more worn, but still about 1 cm long) and the bearings were smooth as glass, so I just re-lubed the brushes, cleaned up the copper and put it back together. I will have to rebuild the broken one for a spare unless it's really pooched. Now i just need to get the pulley off the old one. Good thing I have a garage within a 5 min walk.
