(3) PISTON AND PISTON RINGS
(a) Install each piston ring in the correct groove of
the piston by widening it enough to slide it over
the piston .
NOTE: Be careful not to twist the rings too
much, as they may be damaged . Install
the oil ring first, followed by the top ring .
When installing the piston ring, make
sure that the "R" mark is face up .
