PISTON RING INSTALLATION
NOTE: Apply clean engine oil to all ring surfaces and
ring lands. Always check piston ring installed gap
before rings are installed on piston. If the piston has
been in service, clean any accumulated carbon from
the ring grooves and oil control ring holes.
1. Place the oil control ring expander in oil ring groove with
the end gap facing forward. The expander has no up or down
marking and can be installed either way. The ends should butt
squarely together and must not overlap.
2. Install the oil ring top rail with the end gap at least 30°
 from the end of the expander.
3. Install the bottom rail with the gap at least 30°  from the
end of the expander on the side opposite the top rail gap.
4. Install the second ring with the mark facing up.
Position the end gap toward the rear (intake) side of the piston.
5. Install the top ring with the chamfered edge facing up.
6. Check to make sure the rings rotate freely in the groove
when compressed by hand.
