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)
