Steve, I believe the brushes are NOT available as an MB part. I'd remove the blower assy., check if the bushings are "egg- shaped", if not; sand the commutator, pull the brushes and head off for an electric motor shop in St. Louis with them for a "closest match" and carve to fit. Some one may have a source and will chime in. How's the corn doing around Scott this year...high as an elephant's eye?
