Thickness of new top piston ring is 4.5 mm (0.18 inch).
2 1 144-5695 Intermediate Piston Ring Install the piston ring with the "Up-2" side toward the top of the piston.
When the piston ring is installed in a cylinder liner with a bore size of 170 mm (6.7 inch), the clearance between the ends of the piston ring 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 size is 0.08 mm (0.003 inch).
Width of groove in new crown assembly for the intermediate piston ring is 3.514 mm (0.1384 inch).
Thickness of new intermediate piston ring is 3.785 mm (0.1490 inch).
3 1 165-6668 Oil Control Piston Ring Width of groove in piston for the new oil 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 (0.1570 0.0004 inch).
Clearance between groove and new oil piston ring is 0.050 to 0.100 mm (0.0020 to 0.0039 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 size is 0.08 mm (0.003 inch).
Install the oil piston ring so that the gap in the spring is 180 degrees away from the gap in the piston ring. The colored portion of the spring must be visible at the ring end gap.
- - - After all of the piston rings have been installed, rotate the piston rings so that the end gaps are separated by 120 degrees.
4 1 249-4512 Crown As Measure the pin bore in the bushings in two places for each bushing in a vertical direction.
