Warp 11 Motor Face Modification

The hub adapter as supplied by Pioneer Conversions in Lemont was designed to fit the stock Warp 11 shaft without any modifications, and dimensionally to work with the aluminum adapter set that was also supplied by their contractor.  By contrast, the compression hub adapter that we are developing is designed to utilize as much shaft length as possible.  To allow this newer design, it was necessary to relieve a portion of the end plate of the Warp 11. 

 

To achieve this, the motor was stood on end and a Vice Grip pliers was attached to the opposite end of the shaft over a protective layer of duct tape (don't want to scratch the metal shaft).  The 8 cap head bolts were then removed from the motor and the end plate easily removed to reveal both the internal motor bearing and the cooling fan.

The motor face as supplied by NetGain has a specification 3.997-4.000 inch diameter (ours was delivered with 3.999) and the pilot boss specification is about 0.5 inch high.  The outer diameter of this elevation inserts into the donut spacer of the transmission adapter, which should be slightly above 4.000 inches.
