Anyone who operates a BMW knows that when it comes to repairing their vehicle only the highest quality replacement parts will do. It's not a regular occurrence that you realize that you have to buy a replacement Main Bearing Set to fix your vehicle. While it may not be difficult to buy replacement parts for BMW vehicles, these days the necessity for nothing but the highest quality are required to repair your car or truck. Make no mistake, you didn't buy your 630CSi unless you wanted to buy best-in-class service and dependability both rolled up into one car, truck, or SUV.
A lack of proper lubrication for your internal engine components can result in intense friction and heat and lead to total engine failure. The places where the most rotary movement occurs in your engine are where the crankshaft spins through the main bore, and that is why your BMW 630CSi 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 BMW 630CSi. When properly lubricated, friction and heat are minimized as the main bearings protect your internals for, hopefully, the life of your car or truck.
Don't let a broken Main Bearing Set spell the end of your car, truck, or SUV, and don't gamble with its condition by using anything but the highest quality replacement parts.
