I made an adjustment jig out of an old case. I used a hole saw to cut 
some access holes in the side so I could get to the shift fork clamp 
bolts. It works fine, but you have to be aware that there were 2 case 
styles, so I actually had to make some adaptor shims in order to 
accommodate both styles of trannys.

I would expect bearing dimensions to be MUCH more precise than needed 
here, so that readjustment should not be necessary just because of a 
bearing replacement, but is this the bearing that has a spring behind 
it? If so, you might get the old bearing out, but you would need 
access to the backside to compress the spring and push the shaft back 
into the bearing far enough to get the snap ring on it.
