The brushes ware out and after replacing 2 times the commuters on the armature are so wore that the brushes only last a very short time. I've got one laying around here somewhere that after wearing out, I turned the armature down and put on a small cog pulley. I had intended to adapt a shunt motor to it and just use it as a spindle so as to be very quiet. I bought a Precise precision grinder shortly after and never finished the project. If someone has the time they might consider doing such a job as it would be no more noisy than any A/C motor running.

Great post Dick, warms this ee's cold cold heart ... machining rotating machines ... it just doesn't get any better than that, imo.
Dave, never thought he'd see the words "shunt motor" in a pool forum
