just putting a tip out there that as long as the bearing ID's allow, cam bearing puller can be used in conjunction with a different puller dolly (I just used something I had lying around in the shed for the dolly).
my wheel bearings are 25mm and cam bearings are 1.000" so the puller suits both...
Beats belting them out with hammer and punch. Once one side bearing is out, drifting the other out with something suitable is fine as you can get a nice direct straight hit on it.
I did as well, just make sure you put the bearings back in properly or you will be doing them again. Another post on wheel bearings with lots of stuff on it on this site somewhere.
No worries, but might not hurt to read it, lot of people have problems with them.
