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.
FRONT PISTON INSTALLATION
1- Place rubber tubing over cylinder studs to prevent damage to the pistons and rings during assembly as illustrated in Picture 4.
2- Place a clean piece of plastic sheeting over the crankcase openings to prevent anything from dropping into the crankcase.
3- S&S® pistons have a .020” offset wristpin and the offset must go toward the rear of the engine. Slide the piston wristpin into the piston and
lay the piston with the top side down on your work bench. Using dial or digital calipers take a measurement from the pin to the piston skirt
on both sides as illustrated in Picture 5 and 6 and record your measurement. The measurement with the least amount of distance from
the pin to the skirt will go toward the rear of the engine. A Sharpie® can be used to mark the direction of offset on the piston pin boss as
illustrated in Picture 7.
