          8. CYLINDER/PISTON                                 AGILITY 125


 Measure the piston pin O.D.
 Service Limit: 14.96mm replace if below




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

 Service Limit: 52.3mm 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: 52.50mm 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.
 Service Limits:                                      Top
  True Roundness: 0.05mm repair or replace            Middle
                      if over
  Cylindricity: 0.05mm repair or replace if over      Bottom
