Inner Diameter Of Main Bearing Housing

WARNING: This page is about a different car, the 2004 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

Install the main bearing caps with the main bearings removed, and tighten the mounting bolts to the specified torque.
Using a bore gauge, measure the inner diameter of the main bearing housing.
1. Standard: 63.993 - 64.017 mm (2.5194 - 2.5203 in)
If out of the standard, replace the cylinder block and main bearing caps as an assembly.
NOTE: These components cannot be replaced individually, since they were processed together.
