CONROD BIG END SIDE CLEARANCE
Push the big end of the conrod to one side and measure the
side clearance using a thickness gauge.
If the clearance exceeds the service limit, replace crankshaft
assembly or bring the deflection and side clearance into specifi-
cation by replacing the worn parts. (e.g., conrod, big end bearing
and crank pin)
