Don't do that!!!!
Make sure the snout of the cam is very clean- use a bit of 600 grit if you like. Make sure the new gear is smooth and clean in the bore as well - 600 too. Oil the snout, the bore, line up the timing marks ( you may have to stand on your head to do that) and the keyway, and then gently wiggle the gear, very slightly and it will slide back nicely, enough that a thread or two is exposed. Oil the big nut and wind it on by hand. With hand power, or VERY little wrench power, the nut will pull the gear down onto the snout of the cam.
The snout and the bore are essentially "zero" fit - no slop, no interference. They'll slide a bit when clean and oiled.
