Specification for 244-8850 Piston and Rod Gp
Item Qty Part Specification Description
This piston has a Keystone top ring and a 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.
before assembly of the 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.

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 piston for the intermediate piston ring is 3.514 mm (0.1383 inch).
Thickness of new intermediate piston ring is 3.785 mm (0.1490 inch).
5 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 (0.1567 0.0004 inch).
Maximum thickness of new oil 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).
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).
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).
- - - After all of the piston rings have been installed, rotate the piston rings so that the end gaps are separated by 120 degrees.
6 1 138-8508 Piston Pin Before assembly, lubricate the piston pin bore, the connecting rod eye, and the connecting rod pin bearing with clean engine oil.
Measure the pin diameter on each end in a vertical and horizontal direction.
Outside diameter is 69.962 0.005 mm (2.7544 0.0002 inch).
Length is 137.55 0.15 mm (5.415 0.006 inch).
7 2 8N-7296 Pin Retainer Thickness is 2.40 0.08 mm (0.094 0.003 inch).
