Piston to Piston Pin Oil Clearance
PISTON TO PISTON PIN OIL CLEARANCEPiston Pin Hole Diameter
Measure the inner diameter of piston pin hole with an inside micrometer.
Standard : 21.993 - 22.005 mm (0.8659 - 0.8663 inch)
Piston Pin Outer Diameter
Measure the outer diameter of piston pin with a micrometer.
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" .
NOTE:
^ Piston is available together with piston pin as assembly.
^ Piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts, no piston pin grades can be selected. (Only "0" grade is available.)
