Compress, Yes the brushes are on the white cap part but I'm not 100% sure if you can swap the black casing area. It looked like the spinning magentic cylinder inside the black part of the casing was permantly press fitted on the shaft of the motor. It's pretty cool that the actual impeller part is "floating" within the spinning magnetic cylinder...quite genious as coolant can never get inside the actual motor area. BUT the real wear part are those brushes that contact the motor on the white cap...mine look pretty worn and looks like it caused alot of the black dust. I'm thinking folks could clean out the pump with just the white cap off, buy the $58 pump, and use only the new white cap assembly with the new brushes...it really would only take maybe 30 min to to the whole job too.
