The function and purpose of Main Bearing Set.

Your engine can totally break down from lack of lubrication; resulting in intense friction and heat. The moments where your engine's main caps meet the crankshaft are where all the friction and heat come from, and that is why your Pontiac Grand LeMans main bearings are installed there. These main bearings are made from a composite metal called Babbitt (iron, zinc, copper, aluminum, and more), which is just slightly softer than the forged or cast crankshaft and the main caps in your Pontiac Grand LeMans. Most bearings are cast with lubrication channels, so very little friction is created around the engine main bearings and they will last the life of the vehicle.
