Standard : 21.989 - 22.001 mm (0.8657 - 0.8662 inch)

Piston to Piston Pin Oil Clearance
(Piston to piston pin oil clearance) = (Piston pin hole diameter) - (Piston pin outer diameter)
Standard : 0.002 - 0.006 mm (0.0001 - 0.0002 inch)
^ If the calculated value is out of the standard, replace piston and piston pin assembly.
^ When replacing piston and piston pin assembly, refer to, "HOW TO SELECT PISTON".
