(3) PISTON AND PISTON RINGS

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
fi rst, followed by the top ring.
When installing the piston ring, make sure
that the "N" mark is face up.
