I have a RB25 at the machine shop and am in need of main and rod journal specifications. If anyone has the appropriate information I would appreciate it so we can properly order/size the bearings.

Thanks!

The specs are in the back of the FSM. Everything should be mic'd to make sure the bearing clearances are within the tolerance range. My guess is that you'll probably end up getting STD sized bearings, but you should really take the time to measure.
