Clevite P Series Tri-Metal bearings are the oldest series of Clevite 77 high performance bearings.
The rod bearings in this series typically have the greatest amount of eccentricity. All bearings stamped “Clevite 77” are constructed of trimetal cast copper lead. These bearings have a steelback for support, a cast copper lead lining to withstand the loads of engine operation and an electroplated Babbitt overlay on the running surface to provide searing surface qualities. Most rod bearings are available either with or without dowel holes for use in aluminum rods. Most P series main sets are full grooved to maximize oil flow to the rod 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. Rod bearings use hardened steel back for added strength and resistance to fretting.
Use the P series rods where extremely high RPM’S cause severe rod bore close in. This is typically indicated by nearly full parting line to parting line shaft contact with bearings having less eccentricity. 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.
