Can Be Used Where Extremely High RPM”s Cause Severe Rod Bore Close-In

These aren’t to be puzzled with the usual passenger car and light truck parts for a similar retention applications which even have a P suffix letter. These high performance parts have unique core part numbers different from the usual parts for a similar application. P series parts are the oldest series of Clevite high performance bearings. The rod bearings on this series most often have the best amount of eccentricity. So much rod bearings are either without or with dowel holes to be used in aluminum rods. So much P series main sets are full grooved to maximise oil waft to the rod bearings. Both rods and mains have high crush for max retention and a reduced overlay thickness to stop overlay fatigue every so often known as hen tracking. Rod bearings use a hardened steel back for added strength and resistance to fretting. Extra clearance rod bearings are for 0.001 in. additional clearance and choose fitting. Use the P series rods where extremely high RPMs Lead to severe rod bore close-in. That is most often indicated by just about 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 offer increased oiling to rod bearings. Rod bearing oil starvation is most often indicated by polishing and smearing of the bearing surface in all probability accompanied by discoloration predominantly concentrated on the axial center of the bearings.Features.
