DESCRIPTION
The Main Bearing Set is a crucial component of an engine, specifically designed to reduce friction between the crankshaft and engine block. The 0.020 denotes the size of the bearing, which is slightly larger than standard size to compensate for wear and tear over time. The Part Number 4089846 specifies the unique identifier assigned by the manufacturer for this particular set of bearings. The main function of this component is to support and stabilize the crankshaft while it rotates within the engine block, ensuring smooth operation and preventing damage from metal-to-metal contact. Proper maintenance and replacement of worn bearings can extend the life of an engine and improve overall performance.
