<< Wayne, your decision re: whether you need to pull the crank needs to be
made
 before you install bearings.  If you try to check with plastiguage using old
 bearings you will get false readings because of wear of crank and bearings.

 you will not be able to check out of round, which you must consider.  Bearing
 clearance will need to be in the .0015-.0025 range, which will not leave much
room
 for error.  You may be able to guess at main condition if the rods are ok, as
rods
 are generally first to wear, but look out for rods that were cut before and
mains
 that were not.  John >>

How do I know what oversized bearing to buy without knowing ahead of time how
much clearance is between the existing bearings and crank?
