Clevite MS-1806AL Engine Crankshaft Main Bearing Set

Clevite MS-1806AL Engine Crankshaft Main Bearing Set is a direct replacement bearing kit designed for engines that specify the MS-1806AL main bearing size. Manufactured by Clevite, this set provides the bearing shells required to support the crankshaft main journals and maintain proper oil clearance during operation. By restoring correct clearances, the MS-1806AL bearing set helps reduce journal wear and sustain oil film protection, supporting reliable engine performance during rebuilds or maintenance that require the MS-1806AL specification. Main bearings sit between the crankshaft and engine block, providing pivotal support and a surface for lubrication to form the oil film that minimizes friction during crank rotation. This MS-1806AL set is intended as a precise replacement for engines designed to use that specification, ensuring proper alignment and rotation when reconditioning an engine that calls for MS-1806AL main bearings.
