NOTE

The ring gap for the third compression ring and the

New piston rings should always be used whenever a

lower compression ring is from 0.020 to 0.036 inch

piston is removed for inspection or replacement.

and the gap for the oil control ring is from 0.010 to

(j) When fitting piston rings, the gap be-

0.025 inch.

tween the ends of the rings should be measured

before installing the rings on the piston (fig. 3-60).
