When I did the KDP fix, I pulled the gear off and put it back on , had to fabricate a puller to put on the gear to get it off with heat, then reinstalled it with heat, no problems at all and did not have to remove the cam. Don't know why you would have to buy a new gear. Once it is back on it will not come off unless you take it off.
