Piston To Piston Pin Oil Clearance

Piston Pin Hole Diameter

Measure the inner diameter of piston pin hole with an inside micrometer (A).

Standard: Refer to  "CYLINDER BLOCK ".

Piston to Piston Pin Oil Clearance

(Piston to piston pin oil clearance) = (Piston pin hole diameter) - (Piston pin outer diameter)

Standard: Refer to  "CYLINDER BLOCK ".

• If the calculated value is out of the standard, replace piston and piston pin assembly.
• When replacing piston and piston pin assembly, refer to "DESCRIPTION ".
  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.)
