Clevite Main Bearing Set

P Series (Tri-Metal); Contains Full Narrow Grooved Bearings; Set. P-Series parts are the oldest series of Clevite® high performance bearings. Both rods and mains have high crush for maximum retention, and a reduced overlay thickness to prevent overlay fatigue, sometimes referred to as hen tracking. Use P-Series mains where higher eccentricity is desired to narrow bearing contact patterns and to provide increased oiling to rod bearings. Rod bearing oil starvation is typically indicated by polishing and smearing of the bearing surface, possibly accompanied by discoloration predominantly concentrated at the axial center of the bearings. Clevite® TriMetal engine bearings have been the industry standard since the first patent on the cast, copper, lead composition decades ago. These points are just a few of the advantages Clevite's TriMetal engine bearings: Seizure Resistance, Load Capacity, Embedability & Conformability, Durability.
