wear, the bearings must be inspected visually, and by
feel. Look for signs of discoloration, scoring or galling.
T urn the outer race of each bearing. The bearings
should turn smoothly and quietly. The inner race of
each bearing should fit tightly in the crankshaft. The
outer race should be firm with minimal side to side
movement and no detectable up and down movement.
