What is the purpose of a main bearing?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while handling the immense forces generated during combustion and power delivery.

Why is it important to buy individual bearings?

Engines often require multiple main bearings, and sometimes you only need to replace one or a few due to wear or damage. Purchasing individual bearings allows you to replace only the specific ones needed, which can be more cost-effective for targeted repairs.

What does the 'AL20' in the part number signify?

The 'AL20' typically indicates a specific size or clearance specification for the bearing. In this case, it signifies a 0.020 inch undersize bearing, meaning it's intended for a crankshaft that has been machined down by 0.020 inches.
