I count 72 teeth on the orange driven gear (and 25 on its inner driver). Can anyone confirm?
Looks like the octagon hole could be drilled out to 3/8" and then broached hex fairly easily. A three jaw should locate center well enough, if my 72 count is correct.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
