Being as I have not replaced that bearing , I was speculating .
I was just taking the case bearing mount method as being 'common' to the manufacturer .
It's good to know that heat is not needed .

I have ordered a couple of the 5203 bearings. Should have them by Monday.
If the bearing is 17MM will have a gap of 8MM after it is set into the mag plate.
from the end of the cam to the edge of the pulley is 25MM on this engine.

Here's a pic of the clearance between the back of the mag plate and the drive pulley ( Phelon magneto ) :
