Method of Measurement

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

Install the connecting rod bearings to the connecting rod and the cap, and tighten the connecting rod bolts to the specified torque. Using a inside micrometer measure the inner diameter of connecting rod bearing.
(Oil clearance) = (Inner diameter of connecting rod bearing) - (Outer diameter of crankshaft pin)
1. Standard : 0.028 - 0.045 mm (0.0011 - 0.0018 in)
2. Limit : 0.10 mm (0.0039 in)

If clearance cannot be adjusted within the standard, grind crankshaft pin and use undersized bearing. Refer to HOW TO SELECT A CONNECTING ROD BEARING .
