Offseason WCD with 3 CIM inverted transmission design

The only thing I'd worry about is the four gears (pinion, two idlers, and one more) that are engaged in a square. That center pinion might not fit in there. If it engages with one gear, the other gear may never line up. Unless you've designed for it, both gears that engage with the center pinion could always be slightly misaligned.

It is designed in there.


Also in the second iteration the idler gears will be bearing bore gears on dead axle shafts that extend through both plates in the gearbox.
