| 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) |
