Drill endwise into the interface between the shaft and the gear, so you
have a round keyway, in effect. Then run a tapered reamer down this
"keyway," and drive in a taper pin. Since it looks like the shaft sticks
through the gear, you will have to place a collar over the shaft, so the
drill can be positioned properly half way into the shaft and half way on
the gear.


I'd do something like that, but instead of a taped pin, I'd tap the hole
and screw in a socket head "grub "screw with Loctite. It used to be a
common fix and was called a Scotch key
