5. Inspection and servicing of basic engine parts122(2) Checking the side clearance of a connectingrodFit the respective crank pins to the connecting rod andcheck to make sure that the side clearance in thecrankshaft direction is correct.5.4.2 Crank pin metal(1) Checking crank pin metalCheck for flaking, melting or seizure on the contact surface of the crank pin metal.(2) Measuring crank pin oil clearanceMeasure the crankpin outside diameter and the crankpin metal inside diameter. Calculate the oil clearancefrom the measured values.(Refer to 5.5.1(3) for measuring the crank pin outsidediameter.)Replace the crank pin metal if the oil clearancebecomes about the limit dimension of the below table.Correct by grinding if unevenly wear, roundnessexceeding the limit or insufficient outside diameter isfound. Also use an undersized metal if necessary.[NOTICE]When measuring the inside diameter of the rod bigend, install the crank pin metal in the rod big end notto mistake the top and bottom of the metals andtighten the rod bolts by the standard torque.Standard LimitConnecting rodside clearance 0.20-0.40 0.55N•m (kgf•m)Rod bolt tightening torque 22.6-27.5(2.3-2.8)mmItem Standard LimitCrankpin O.D. 41.952-41.962 41.902Metal I.D. 41.982-42.010 -Metal thickness 1.503-1.509 -Clearance 0.020-0.058 0.120(Connecting rod side gap)CrankshaftThickness gageCylinder gage(Rod bushing I.D. measurement)
