This is a NEW style upgraded motor designed to fit your machine.  There is no longer a need for an external fan, but the flywheel will need to be transferred from your previous motor.  This motor will look different but will be installed the same.  We will honor the price of the OEM motor if you wish to proceed. 

Here is video to help assist with the transfer of the flywheel.
