(1) Top compression ringWidth of top compression ring ... 2.068 mm to 2.097 mm (0.08142 inch to 0.08256 inch)Ring gap ... 0.112 mm to 0.157 mm (0.00441 inch to 0.00618 inch)Note: When you install a new top compression ring, make sure that the word "TOP" is facing the top of the piston. New top piston rings have a black identification mark. The identification mark must be on the left of the ring end gap when the top piston ring is installed on an upright piston. (2) Intermediate compression ringWidth of intermediate compression ring ... 1.970 mm to 1.990 mm (0.07756 inch to 0.07835 inch)The clearance between a new intermediate compression ring and the piston groove in a new piston ... 0.06 mm to 0.16 mm (0.00236 inch to 0.00630 inch)Ring gap ... 0.060 mm to 0.100 mm (0.00236 inch to 0.00394 inch)Note: When you install a new intermediate compression ring, make sure that the word "TOP" is facing the top of the piston. New intermediate rings have a blue identification mark. The identification mark must be on the left of the ring end gap when the top piston ring is installed on an upright piston. (3) The oil control ringWidth of oil control ring ... 2.470 mm to 2.490 mm (0.09724 inch to 0.09803 inch)The clearance between a new oil control ring and the groove in a new piston ... 0.015 mm to 0.05 mm (0.00059 inch to 0.00197 inch)Ring gap ... 0.050 mm to 0.090 mm (0.00197 inch to 0.00354 inch)Note: When you install a new oil control ring, make sure that the word "TOP" is facing the top of the piston. New oil control rings have a red identification mark. The identification mark must be on the left of the ring end gap when the top piston ring is installed on an upright piston. The oil control ring is a two-piece ring that is spring loaded. A pin is used to hold both ends of the spring of the oil control ring in position. The ends of the spring of the oil control ring must be installed opposite the end gap of the oil control ring.Note: Ensure that the ring end gaps of the piston rings are spaced 120 degrees from each other.Piston
