A lot of the times they only need a good cleaning up on the inside and a light lube on the bushes and clean out the gaps carefully on the commutator and if the brushes look worn pick up some new ones at the local auto electrician. He just might have the same size and shape as to what you need, if not a set nearly the same and file them to shape as they are only carbon and file easily.
