What is the purpose of crankshaft main bearings?

Crankshaft main bearings support the crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to spin smoothly while maintaining precise alignment, which is crucial for engine health and performance.

What does 'flanged bearing thrust' mean?

Flanged bearing thrust refers to bearings that have a lip or flange on one side. This design helps to control the forward and backward movement (axial thrust) of the crankshaft, preventing it from moving too far in either direction.

Do I need to replace all the main bearings when rebuilding?

Yes, it's standard practice to replace all main bearings as a set during an engine rebuild. This ensures consistent wear patterns and proper support across the entire crankshaft, which is essential for the longevity of the engine.
