Piston And Piston Pin Clearance

WARNING: This page is about a different car, the 2009 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

Inner Diameter of Piston Pin Hole

Measure the inner diameter of piston pin hole "dp".

Piston and Piston Pin Interference Fit

Standard Interference Fit = "Dp" - "dp"

Standard: 0.002 - 0.010 mm (0.0001 - 0.0004 in)
If clearance is exceeds specification, replace either or both of piston/piston pin assembly and connecting rod assembly with reference to specification of each part.
