Clevite Rod BearingsConnecting Rod Bearing SetClevite rod bearings come in a wide assortment of styles for ahuge range of vehicles, from mild to wild. Theyre made to meet orexceed OEM standards for strength and durability, andwill help give your engine extra life. Their quality constructionand superior materials protect vital parts from the harmful effectsof friction. Plus, there are thousands of applications, with subtledifferences that cover numerous variations and usages. So youresure to find the bearings you need for your engine.P-Series BearingsThese are not to be confused with the standard passenger car andlight truck parts for the same retention applications which alsohave a P suffix letter. These high performance parts have uniquecore part numbers different from the standard parts for the sameapplication. P-Series parts are the oldest series of Clevite highperformance bearings. The rod bearings in this series typicallyhave the greatest amount of eccentricity. Most rod bearings areavailable either with or without dowel holes for use in aluminumrods. Most P-Series main sets are full grooved to maximize oil flowto the rod bearings. Both rods and mains have high crush formaximum retention, and a reduced overlay thickness to preventoverlay fatigue, sometimes referred to as hen tracking.Rod bearings use a hardened steel back for added strength andresistance to fretting. Extra clearance rod bearings are availablefor .001 additional clearance and select fitting. Use the P-Seriesrods where extremely high RPMs cause severe rod bore close-in.This is typically indicated by nearly full parting line to partingline shaft contact with bearings having less eccentricity. UseP-Series mains where higher eccentricity is desired to narrowbearing contact patterns and to provide increased oiling to rodearings. Rod bearing oil starvation is typically indicated bypolishing and smearing of the bearing surface, possibly accompaniedby discoloration predominantly concentrated at the axia
