You would insert the collar into the 1/2" hole and then insert the broach into the slot in the collar and use a press to push the broach through (use plenty of cutting oil), which will cut a keyway into the gear to interface with the shaft.

Here is a quick youtube video showing the process: https://www.youtube.com/watch?v=ZRbOux9NfeU
