Piston To Piston Pin Clearance

WARNING: This page is about a different car, the 2012 Nissan Pathfinder. 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 inside micrometer.

Standard: 21.993 - 22.005 mm (0.8659 - 0.8663 in)

Piston Pin Outer Diameter

Measure the outer diameter of piston pin with micrometer.

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

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 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 AND BEARING ".
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.)
