Checking Piston Ring Gap





Checking Ring Groove Clearance

Checking piston
^ Measure approximately 6 mm from lower edge, perpendicular to piston pin axis. Use an external micrometer, 75...100 mm, to measure.
^ Max. deviation from nominal dimension: 0.04 mm





Checking cylinder bore
^ Make measurements at three positions diagonally in transverse direction -A- and in longitudinal direction -B-. Use a cylinder gauge, 50...100 mm, to measure.
^ Max. deviation from nominal dimension: 0.08 mm
