(6) Connecting rodTall aluminum pistons are used in the 230 horsepower engines and up. (A) Height of the tall piston ... 101.00 0.27 mm (3.976 0.011 inch)Note: Assemble the rod and aluminum pistons with the marking "front" on the piston body in the opposite direction of the part number on the rod assembly. Install the rod and piston group in the engine with the part number on the rod assembly to the rear of the engine. The rear of the engine is the flywheel end of the engine. Lubricate the rod and piston group with clean engine oil before you insert the rod and piston group into the block.Lubricate the entire piston body assembly (1) to 360 degrees in zone (A) prior to assembly into the cylinder block. Use clean unused engine oil.Top Piston Ring (2)

The white colored stripe faces to the right of the piston ring end gap.Thickness of the new top piston ring ... 3.5 mm (0.14 inch)Clearance between the ends of the piston ring in a cylinder liner bore of 110 mm (4.3 inch) ... 0.37 0.07 mm (0.015 0.003 inch)Increase in clearance between the ends of the piston ring for each 0.03 mm (0.001 inch) increase in the cylinder liner bore ... 0.09 mm (0.004 inch)Intermediate Piston Ring (3)
Note: Install the intermediate piston ring with side marked "UP-2" toward the top of the piston. The orange colored stripe faces to the right of the piston ring end gap.Thickness of the new intermediate piston ring ... 2.980 0.010 mm (0.1173 0.0004 inch)Clearance between the ends of the piston ring in a cylinder liner bore of 110 mm (4.3 inch) ... 0.80 0.12 mm (0.031 0.005 inch)Increase in clearance between the ends of the piston ring for each 0.03 mm (0.001 inch) increase in the cylinder liner bore ... 0.09 mm (0.004 inch)Oil Control Piston Ring (4)
Note: The ends of the oil control piston ring should be a distance of 180 degrees from the ring end gap when the oil control piston ring is assembled. The brown colored stripes can be to the right of the ring end gap or to the left of the ring end gap.Thickness of the new oil control piston ring ... 3.985 0.010 mm (0.1569 0.0004 inch)Clearance between the ends of the piston ring in a cylinder liner bore of 110 mm (4.3 inch) ... 0.37 0.15 mm (0.015 0.006 inch)Increase in clearance between the ends of the piston ring for each 0.03 mm (0.001 inch) increase in the cylinder liner bore ... 0.09 mm (0.004 inch)Note: After the piston rings have been installed rotate the piston rings so that the end gaps are 120 degrees from each other.Piston Pin (5)
