7. CYLINDER/PISTON People GT 125i PISTON/PISTON PIN Measure the piston O.D. at the point (A) from the bottom and 90° to the piston pin hole. TOP Calculate the cylinder-to-piston clearance. MIDDLE Standard: 52.3752.39 mm BOTTOM CYLINDER Check the cylinder for warpage with a straight edge and feeler gauge in the directions shown. Check the cylinder wall for wear or damage. Measure and record the cylinder I.D. at three levels in an X and Y axis. Take the maximum reading to determine the cylinder wear. Calculate the piston-to-cylinder clearance. Take a maximum reading to determine the clearance. Calculate the taper and out-of-round at three levels in an X and Y axis. Take the maximum reading to determine them. CONNECTING ROD Measure the connecting rod small end I.D. Calculate the connecting rod-to-piston pin clearance. Service Limit: 0.02 mm (0.0008 in) 7-6
