This sucks. They changed their web site. The hub & set screw option isn't offered now. I hope they changed it in the last day or so since you contacted them.

How deep of a hole did you have machined out of the gear? I think it needs to be 4mm deep to have enough of the shaft sticking out the other side to fit on the bearing.

I'm going to a machine shop this morning.

What size set screw did you use in the pinion?
