          8. CYLINDER/PISTON                                          AGILITY 50

 Measure the piston pin O.D.
 Service Limit:12.96mm replace if below




 Measure the piston O.D.
 Take measurement at 9mm from the
   bottom and 90° to the piston pin hole.

 Service Limit: 38.9mm 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: 39.10mm 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
 values measured at the three levels) is subject
 to the maximum value calculated.                    Top
 Service Limits:
  True Roundness: 0.05mm repair or replace         Middle
                      if over
  Cylindricity: 0.05mm repair or replace if over
