Note: Please browse entire page before making your electric motor selection

If your motor is part of the compressor head-we do not have a replacement motor, it is
only available from the manufacture, such as Coleman or Sears. If your motor mount pivots,
like some Sears models, we do not sell that motor. All our compressor motors are designed
to drive a belt with a pulley and have a flat mounting base. (56 frame = 3" x 5" bolt pattern)
