Specification for 223-6363 Piston and Rod Gp    
Item     Qty     Part     Specification Description    
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 installation of the piston 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     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.

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 of new 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 mm to 4.07 mm (0.159 to 0.160 inch).
Thickness of new oil control piston ring is
3.980 0.010 mm (0.1567 0.0004 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 mm to 0.8 mm (0.02 to 0.03 inch).
