Description

The Clevite MS-1804P-.25MM is a set of engine main bearings designed as a direct replacement. These P-Series bearings are constructed from tri-metal TM-77 material, featuring a steel back for support and a cast copper lead lining. They include an electroplated babbitt overlay on the running surface for enhanced durability.

These bearings are engineered with higher eccentricity and a high crush factor to compensate for high-load factors and distortion, making them suitable for high-revving engines. The oil grooves on most applications extend fully around both halves for improved oiling. The set includes five bearings and is specified for a 0.25mm crankshaft undersize.
