What is the purpose of main bearings in an engine?

Main bearings sit between the crankshaft and the engine block. They support the crankshaft, allowing it to rotate smoothly while maintaining precise oil clearance. This prevents metal-on-metal contact and reduces friction and wear.

What does 'flanged bearing thrust' mean for these bearings?

Flanged bearings have a lip or flange on one side. In this application, they help control the fore-and-aft movement, or end play, of the crankshaft. This is crucial for keeping the crankshaft properly positioned within the engine block.

Are these bearings a direct replacement for the original parts?

Yes, these ACL main bearings are designed as a direct replacement for the original equipment on the specified 1983-1992 Ford Ranger V6 models. Proper installation is essential for them to function correctly.
