Piston Pin

Piston pin





1. Measure each piston pin hole diameter at X and Y directions in four locations shown in figure.
Diameter: 0.7872 - 0.7875 inch (19.994 - 20.002 mm)





2. Measure each piston pin diameter at X and Y direction at four locations shown.
Diameter: 0.7869 - 0.7871 inch (19.987 - 19.993 mm)
3. Subtract piston pin diameter from pin hole diameter to determine piston pin to piston clearance.
Clearance: 0.00004 - 0.00006 inch (0.001 - 0.015 mm)
4. If clearance exceeds specification, replace piston and piston pin.

Notice: Piston and piston pin are a matched set.
