Measure each piston pin hole diameter at the four points shown.

Replace piston that is not within specifications.





Use a micrometer to inspect the piston pin diameter in the X and Y directions at points A, B. C and D as shown.

Calculate piston pin to piston pin hole clearance by subtracting pin diameter from piston pin hole diameter.

Replace piston pin that is not within specifications.
