All new piston rings must be
installed whenever a piston is
removed, regardless of whether
a new or used piston or
cylinder liner is installed.
(6)
Insert one ring at a time
inside of the cylinder liner
and far enough down to be
within the normal area of
ring travel. Use a piston to
push the ring down to be sure
it is parallel with the top
of the liner. Then measure
the ring gap with a feeler
gage. Refer to ring gap
specifications.
