My rear bearing isn't exactly a press fit into the crankcase but it's tight enough.

The cam gear bearing is the bugger, the one in the cap comes out just fine with heat and a quick tap, but I always find myself bending up different shape pieces of wire and other oddments to get the crankcase one out. I've vowed to make up a tool but I'm just to lazy.

I just replaced the cam bearings with the ones I had in stock, and you can change them without pulling the head (or throttle) off. I just slid the tappets off their pivots, pushed up the lifters, pulled the cam gear, removed the lifters, pulled the bearing and put it back together in reverse order.

I did put a timing mark on the prop driver first though!!
