Piston And 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 diameter of piston pin hole using suitable tool.

Standard: 21.993 - 21.999 mm (0.8659 - 0.8661 in)

Piston to Piston Pin Clearance

(Piston pin clearance) = (Piston pin hole diameter) - (Piston pin diameter)

Standard: 0.002 - 0.006 mm (0.0001 - 0.0002 in)

If clearance exceeds specification, replace either or both the piston/piston pin assembly and the connecting rod assembly with reference to the specification of each part.
Use the piston selection table to replace piston/piston pin assembly. Refer to "HOW TO SELECT PISTON AND BEARING ".
Use the connecting rod bearing selection table to replace connecting rod. Refer to "HOW TO SELECT PISTON AND BEARING ".
NOTE: The connecting rod small end grade and piston pin hole (piston pin) grade are provided only for the parts installed at the plant. For service parts, no grades can be selected (only 0 grade is available).
Follow the connecting rod bushing oil clearance (small end) procedure for the values for each grade at the plant.
