Illustration 1 g00845975 (1) The chamber that is on the top of the piston must face the right side of the engine. (2) The Shibaura name that is on the inside of the piston must align with the stamped number on the connecting rod. Piston and Piston Rings
Illustration 2 g00845969Use a feeler gauge to measure the clearance between the piston ring groove and the piston ring. If the clearance is greater than the service limit, use a new piston ring and check the clearance.If the clearance is within the service limit, renew the piston rings. If the clearance is outside of the service limit, renew the piston. (1) Top piston ring Shape of top ring (A) Naturally aspirated ... Barrel faceTurbocharged ...

When either the intermediate ring or the oil control ring is outside the service limit, renew all of the rings.Note: Install the word "Top" toward the top of the piston. New top piston rings have a red identification mark which must be on the left of the ring gap when the top piston ring is installed on an upright piston.Note: New top piston rings for the C2.2/3024CT have a yellow identification mark which must be on the left of the ring gap when the top piston ring is installed on an upright piston.Note: The top surface of the piston ring should be equally distant from the top face of the cylinder block at all points before the piston ring end gap is measured with a feeler gauge.
