Description

The Clevite MS1718P25MM is a set of P-Series main bearings designed for Cummins B Series 4-cylinder engines. These bearings feature a tri-metal construction with TM-77 material and are manufactured to OEM-equivalent standards for reliability and durability.

Each bearing in the set includes a 1/2 groove style located in the upper position, with oil grooves that extend around both halves for improved oiling. They are designed for a 0.010 in. (0.25mm) crankshaft undersize, compensating for high-load factors and potential distortion in high-revving engines.
