Specification for 160-5910 Piston and Rod Gp
Item Qty Part Specification Description
This piston has a Keystone top ring. This piston also has Keystone intermediate rings. The 204-8041 Piston Ring Groove Gauge Gp is necessary for measuring the ring grooves in the Keystone pistons. For correct use of the gauge group, refer to the instruction card that is with the gauge group.
Prior to the installation of the rings, lubricate the ring grooves with clean engine oil. Lubricate the mating surfaces of the rings to the cylinder liner with clean engine oil, after assembly.
1 1 229-1632 Top Piston Ring Install the piston ring with the "Up-1" 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 0.625 0.125 mm (0.0246 0.0049 inch).
The increase in the 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).
Thickness of the 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).
The increase in the 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).
Thickness of the 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 piston ring is 3.980 0.010 mm (0.1567 0.0004 inch).
Clearance between groove and new oil piston ring is 0.050 mm to 0.100 mm (0.0020 mm to 0.0039 inch).
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 0.65 0.15 mm (0.026 0.006 inch).
The increase in the 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 white 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. The ring gap for the oil piston ring must be aligned in the plane of the pin bore.
