Piston Installation
1. Before installing new piston rings, check gap between ring ends by placing each ring
in its respective cylinder, then pushing ring about 1/2 in. (12.7 mm) into cylinder using
piston to assure proper position.
2. Check end gap of each new piston ring with a feeler gauge. End gap must be within
0.010 in. to 0.018 in. (0.25 mm to 0.45 mm). If end gap is greater, check other piston
rings in cylinder bore, until rings (within tolerance) are found.
IMPORTANT: Piston ring side with dot or letter must be facing up.

piston. Spread rings just enough to slip over piston.
4. Check piston rings to be sure that they fit freely in ring groove.
5. Lubricate piston, rings and cylinder wall with 2-Cycle Outboard Oil.
