Item Qty Part Specification Description
Refer to Guideline for Reusable Parts for information on the pistons, the piston pins, and the retaining rings.
This piston has a square top piston ring. Use the 246-1176 Piston Ring Groove Gauge Gp for measuring the top piston ring groove.
This piston has a keystone type of intermediate piston ring. Use the 1U-6431 Piston Ring Groove Gauge Gp for measuring the intermediate piston ring groove. For correct use of the piston ring groove gauge group, refer to the instruction card that is with the piston ring groove gauge group.
Before assembly of the piston rings, lubricate the ring grooves with clean engine oil. After assembly, lubricate the mating surfaces of the rings to the cylinder liner with clean engine oil.
1 1 214-6066 Top Piston Ring Install the top piston ring with the "UP-1" side toward the top of the piston.
When the new top 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 0.625 0.125 mm (0.0246 0.0049 inch).
Thickness of new top piston ring is 3.88 mm (0.153 inch).
2 1 144-5695 Intermediate Piston Ring Install the intermediate piston ring with the "UP-2" side toward the top of the piston.
When the new intermediate 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).
Thickness intermediate piston ring is 3.785 mm (0.1490 inch).
3 1 223-6361 Oil Control Piston Ring 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.
Width of groove in new piston for the oil control piston ring is 4.04 to 4.07 mm (0.159 to 0.160 inch).
Thickness oil control piston ring is 3.97 to 3.99 mm (0.156 to 0.157 inch).
When the new oil control 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 0.5 to 0.8 mm (0.02 to 0.03 inch).
After the piston rings have been installed, rotate the piston rings so that the end gaps are 120 degrees from each other.
4 - - Bore diameter for piston pin is 70.0705 0.0075 mm (2.75867 0.00030 inch).
5 1 263-8955 Piston Pin Before assembly, lubricate the piston pin, the piston pin bore, the connecting rod eye, and the connecting rod pin bearing with clean engine oil.
Outside diameter is 69.930 0.005 mm (2.7531 0.0002 inch).
