I have a 1951 vintage elevator in my building. It has a starter generator which is maybe four feet long and nearly two feet in diameter. My elevator repairman told me yesterday the the commutators are getting carboned up and need cleaning between.

Naturally getting this maybe 3000 pound motor off the sixth floor level and out a window is something I would love to avoid doing, not to mention the loss of the use of the elevator for at least a week.

Are there tools available to clean the commutators in place and people with the skill to do this?
