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- Check the ring end gap by placing the ring into the cylinder. Use a piston or caliper to ensure that the ring is placed squarely in the bore as
illustrated in Picture 1.
2- Measure the ring end gap with a feeler gauge as illustrated in Picture 2.
