Balancer Unit Mounting Bolt Outer Diameter

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.

Measure outer diameters (d1, d2) at the two positions shown in the figure.
Measure d2 within the range A.
If the valve difference (d1 - d2) exceeds the limit (a dimension difference is large), replace it with a new one.
