Piston To Piston Pin Oil Clearance: Notes

WARNING: This page is about a different car, the 2011 Infiniti M56. However, it is still accessible from the selected car via links, so may be relevant.

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.
