How do you put 2 CIM motors into a Dewalt transmission?

We did it in 2006 with no failures to the Dewalts. We built custom adaptor gearboxes to mount two CIMs. We used the 14 to 50 first stage reduction gears that came in the KOP trans to go from the CIMs to a single output shaft. The output shaft from the custom box drove the second stage planetary set in the Dewalt. We took the Dewalt first stage section out like the White paper Nothing But Dewalts describes for use with a single CIM motor. [url="http://www.chiefdelphi.com/media/papers/1592"] Instead of boring out the ID of the carrier sun gear and pressing it onto the CIM shaft, we made a custom aluminum adaptor that attached to the carrier sun gear using the four screws shown to attach the plastic top hat. This adaptor had a keyed ID that fit the keyed output shaft of the custom gearbox. The other thing that is important to do is to support nose of the Dewalt casting section. If you don't the cantilever hanging out there will probably pull the small screws holding the Dewalt to the gearbox case out.
