Hi Chris
The biggest problem with these small nylon gears is that
nothing sticks well to nylon. When you push it back on the shaft, it
will break most any bond.
What I recommend is that you core out the center of the gear so
that is just slides onto the shaft without and tension. You make
sure the inner surface is a little rough. Use JB Weld to glue it
on. Don't over drill the center or you won't be able to get a
good centering. Make sure things are clean and that gravity doesn't
allow the JB Weld to run into the bearing while setting. Use a
good cleaner, like brake clean ( automotive product ).
