CYLINDER WEAR CHECK (Fig. 10-57)
The measurement of the cylinder diameter must be made at three heights, turning the feeler gauge by 90°. It is
also important to check that the cylinders and the pistons are of the same selection class (A, B, C).
Grading cylinder diameter
GRADE A GRADE B
92,000÷92,006 92,006÷92,012 92,012÷92,018
Grading piston diameter
GRADE A GRADE B
91,954÷91,960 91,960÷91,966 91,966÷91,972
NOTE: The «A», «B», «C» grade cylinders must be coupled with the corresponding pistons in the
grades «A», «B», «C» (Fig. 10-46).
The grading measurements indicated in the tables must be taken at 14 mm from the lower edge of the piston,
at right-angles to the gudgeon pin axis.
