7. CYLINDER/PISTON PEOPLE/PEOPLE S 250 Measure the piston pin O.D. Service Limit: 16.96mm replace if below Measure the piston O.D. · Take measurement at 9mm from the bottom and 90° to the piston pin hole. Service Limit: 72.60mm replace if below Measure the piston-to-piston pin clearance. Service Limit: 0.02mm replace if over CYLINDER INSPECTION Inspect the cylinder bore for wear or damage. Measure the cylinder I.D. at three levels of top, middle and bottom at 90° to the piston pin (in both X and Y directions). Service Limit: 72.80mm repair or replace if Over Measure the cylinder-to-piston clearance. Service Limit: 0.1mm repair or replace if Over The true roundness is the difference between the values measured in X and Y directions. The cylindricity (difference between the Top values measured at the three levels) is subject to the maximum value calculated. Service Limits: Middle True Roundness:0.09mm repair or replace if over Cylindricity: 0.09mm repair or replace if over Bottom 7-5
