Question 1

What does '40' mean in the part number?

Accepted Answer

The -40 suffix in the part number 8B610A-40 indicates a 0.040 inch undersize bearing set. This means the bearing is designed for crankshafts that have been ground down 0.040 inches during a rebuild.

Question 2

How do I know if I need undersized bearings?

Accepted Answer

During an engine rebuild, the crankshaft journals are often machined to remove imperfections. If your crankshaft has been ground, you'll need undersized bearings to maintain the correct oil clearance. Your machinist will specify the correct undersize.

Question 3

Are these bearings compatible with all Buick 300, 340, and 350 V8 engines?

Accepted Answer

This ACL 8B610A-40 connecting rod bearing set is designed to fit Buick V8 engines with 300, 340, or 350 cubic inch displacement manufactured between 1961 and 1981. Always verify fitment using manufacturer data to ensure compatibility with your specific engine.
