3- See table for proper end gap measurement. If adjustment to the gap must be made, use a proper ring end gap filing tool.

5- Remove material from only one end of the ring.
6- Ensure that ring end gaps are square.
7- Remove sharp edges and burrs.
8- Recheck gap measurement and adjust as necessary.

PISTON RING INSTALLATION
NOTE: The top piston ring has a shiny chrome color and has a letter “N” that designates the top of the ring. The second ring has a dull black finish and has
a letter “N” that designates the top of the ring. In both cases the letter “N” should face upwards toward the top of the piston. The oil rails and expanders
can be installed in either direction.
1- Install the oil ring expander to the bottom groove of the piston. The expander ring has a gold finish. Make sure the end of the expander ring
is butted together and not overlapping. If the tips are overlapped, excessive oil consumption will occur. Orient the expander gap according
to the diagram below.
2- Install oil rails. The oil rails are the thinnest of all the rings. Either side can be placed up. Use a ring expander to install the rails into the groove.
Install one rail above the expander, and one below.
3- Install the 2nd ring with the letter “N” facing up. The 2nd ring has a dull black finish. Use an expander to install the ring to the 2nd groove in the
piston.
4- Install the top ring with the letter “N” facing up. The top ring has a shinny chrome color. Use an expander to install the ring to the top groove.
