Illustration 1 g01611477This piston has a Keystone top and Keystone intermediate rings. The 1U-6431 Piston Ring Groove Gauge is necessary for measuring the ring grooves in Keystone pistons. For correct use of the gauge group, see the instruction card that is with the gauge group.Top Piston Ring (1)
Install the top ring with the "Up-1" side toward the top of the piston.Thickness of new top piston ring ... 3.91 mm (0.154 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 the following value. ... 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 the following value. ... 0.08 mm (0.003 inch)Intermediate Piston Ring (2)
Install the intermediate ring with the "Up-2" side toward the top of the piston.Thickness of new intermediate piston ring ... 3.785 mm (0.1490 inch)When the piston 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 the following value. ... 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 the following value. ... 0.08 mm (0.003 inch)Oil Control Piston Ring (3)
