Piston And Piston Pin Clearance

WARNING: This page is about a different car, the 2003 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

Measure inner diameter of piston pin hole "dp".
Standard diameter "dp":

Grade No. 0

21.993 - 21.999 mm (0.8659 - 0.8661 in)

Grade No. 1

21.999 - 22.005 mm (0.8661 - 0.8663 in)

Measure outer diameter of piston pin "Dp".
Standard diameter "Dp":

Grade No. 0

21.989 - 21.995 mm (0.8657 - 0.8659 in)

Grade No. 1

21.995 - 22.001 mm (0.8659 - 0.8662 in)

Calculate interference fit of piston pin to piston.
Dp - dp = 0.002 - 0.006 mm (0.0001 - 0.0002 in)

If it exceeds the above value, replace piston assembly with pin.
