Wayne, plastiguage is used to measure bearing to journal clearance. If you are
going to replace bearings you need to first measure the journals with a mike to
check wear/size/out of round. Also examine for scoring. Then determine whether
the crank needs to be turned. When you reassemble with new bearings use
plastiguage to check clearance. John
