[T2] Identifying bearing sizes

[Monty Rowden]

Hello all.  How do I know what size my case has been bored out to upon disassembly of my engine.  The center main bearing is the only one with numbers on the backside of it.  And it says .25. Is this what the crank was turned at or the case.  It is a type 4 case.  I realize not to many type 4 cases need to be line bored.  Just need help identifying.  Thanks!
