c) Piston side clearance z Assemble the piston ring at the z Measure the each ring’s side piston. Feeler gauge clearance and if the measured value exceeds the limit value, replace rings or piston. EA4M2007 4) Piston pin a) Outside diameter z With the outside micrometer, measure the piston pin’s outside diameter and if the value is same as the use limit value or less, replace it. EA0M4031 b) Piston pin and connecting rod bush clearance z Inspect the clearance between the piston pin and the connecting rod bush, if it is more than the use limit value, replace either one that is more severe.
