Below is the finished steel adapter that mates the Warp 9 motor shaft to the light weight flywheel. It has a keyway and hardened steel key matched to that of the motor and a set screw that will seat in a depression machined into the shaft as an extra safety measure.
Installing this piece requires some care and precision as the distance from the face of this part to the face of the transmission adapter flange to ensure a proper engagement of the drivetrain assembly.
