7. CYLINDER/PISTON DINK50/ 125 Cylinder Check the cylinder for warpage with a straight edge and feeler gauge in the directions shown. Service Limit: 0.05 mm (0.002 in) Check the cylinder wall for wear or damage. Measure and record the cylinder I.D. at three TOP levels in an X and Y axis. Take the maximum reading to determine the cylinder wear. MIDDLE Service Limit: 52.5 mm (2.1 in) BOTTOM Calculate the piston-to-cylinder clearance. Take a maximum reading to determine the clearance. Service Limit: 0.1 mm (0.004 in) Calculate the taper and out-of-round at three levels in an X and Y axis. Take the maximum reading to determine them. Service Limit: Taper: 0.1 mm (0.004 in) Out-of-round: 0. 1 mm (0.004 in) Measure the connecting rod small end I.D. Service Limit: 15.06 mm (0.6024 in) Calculate the connecting rod-to-piston pin clearance. Service Limit: 0.02 mm (0.0008 in) 7-8
