I don't think it's that bad, John. In all my years using brushed motors, all I have had to do is blow out the dust every few years with compressed air, and everything was fine. However, if enough dust accumulated for the motor to "flash over" from high voltage, it could have created a carbonized path. In that case, you'd have to pull the motor, take it apart to survey the damage, and repair or replace the brusholder accordingly. -- Excellence does not require perfection. -- Henry James But it *does* require attention to detail! -- Lee Hart -- Lee A.
