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 in) 

• If oil clearance is out of the standard, replace piston and piston pin assembly.
• When replacing piston and piston pin assembly, refer to [SERVICE DATA AND SPECIFICATIONS ].
  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 grades can be selected. (Only grade "0" is available.)
