This is the puller I made for the Rollmaster lower gear. It allows you to use some threaded studs to pull the gear off evenly and without damage. I made this after I installed the Rollmaster and needed to pull it back off for degreeing and found it was even harder coming off than it was going on. After I pulled it, I honed the ID to make it a looser fit, so the puller is still used but it's not doing much work.
