Motor to Transmission Adapter Plate

In order to mount the electric motor to the existing transmission a plate needed to be fabricated.

To make the center hole, which will allow me to mount the plate to the transmission in order to get an exact center for the motor mounting holes.

The 2″ hole was simply drilled in with a hole saw in a hand drill. Lots of lubricant (WD-40) was used, as well as a slower speed and lots of breaks. Aluminum is very easy to work with compared to steel. The plate is .500″ thick 6061. A 12″x13″ piece cut and shipped cost $80.

I have ordered a part made which will connect the shaft from the electric motor to the splined shaft on the transmission. It will be fabricated in part using the old clutch. Any further progress mounting the motor must wait for this.
