If the connecting rod end play is out-of-tolerance, install a new connecting rod, and recheck. If it is still out-of-tolerance, replace the crankshaft (see OIL PAN REMOVAL ).
Push the crankshaft firmly away from the dial indicator, and zero the dial against the end of the crankshaft. Then pull the crankshaft firmly back toward the indicator; the dial reading should not exceed the service limit.
Crankshaft End Play

Standard (New): 0.10-0.35 mm (0.004-0.014 in.)
