FOR PARTS Sterling 10 1 Electric Gear Motor w Leeson 1HP DC motor 23753

  For sale is a Sterling 10:1 Electric Gear Motor;
  Leeson 1HP DC motor
  Ratio 10:1
  90VDC; 10A;
  Shaft - 1"

  This motor works, however it probably needs brush replacement. 
  I powered it by DC and it would spin, but somewhat erratically
  as if the brush was worn out. Out of three screws holding the rear 
  fan cover only one screw works.
