I tried different bearings, swapping halves to see if it were a bearing issue. It is definitely not the bearings, as the measurements came out differing the same when I measured the bores minus bearings. The back side was still .0015 larger. Plenty of room around the studs, checked for that and found the holes all consistantly .530, studs .497. The studs are perfectly centered, allowing cap placement way forward or backward to get proper bearing alignment of the #3. Plenty of room side to side as well.
Any one have the specs for max minimum bearing bore diameter for proper bearing crush? Standard rb bearings.
