Item Qty Part Specification Description
Prior to the installation of the piston rings, lubricate the ring grooves with clean engine oil. After assembly of the piston rings, lubricate the mating surfaces of the rings to the cylinder liner with clean engine oil.
1 1 229-1632 Top Piston Ring Install the top piston ring with the "UP-1" side toward the top of the piston.
Thickness of new top piston ring is 4.5 mm (0.18 inch).
Clearance between the ends of the piston ring when the piston ring is installed in a cylinder liner bore of 170 mm (6.7 inch) is 0.625 0.125 mm (0.0246 0.0049 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 is 0.08 mm (0.003 inch).
2 1 144-5695 Intermediate Piston Ring Install the intermediate piston ring with the "UP-2" side toward the top of the piston.
Thickness of new intermediate piston ring is 3.785 mm (0.1490 inch).
Clearance between the ends of the piston ring when the piston ring is installed in a cylinder liner bore of 170 mm (6.7 inch) is 1.00 0.15 mm (0.039 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 is 0.08 mm (0.003 inch).
3 1 165-6668 Oil Control Piston Ring Ends of the oil control piston ring should be a distance of 180 degrees from the ring end gap when the piston ring is assembled. The colored portion of the piston ring must be visible at the ring end gap.
Width of groove in new piston for the oil control piston ring is 4.055 0.015 mm (0.1596 0.0006 inch).
Thickness of new oil control piston ring is 3.980 0.010 mm (0.1567 0.0004 inch).
