Clevite CB684P10 Rod Bearing

General Motors Clevite 77, Tri-Metal Connecting Rod Bearings fit the following:260 CID 4.3L LV8 Oldsmobile V8 cylinder 1975-1982,350 CID 5.7L Oldsmobile V8 cylinder 1968-1980,307 CID 5.0L Oldsmobile V8 cylinder 1980-1990,330 CID 5.4L OHV Oldsmobile V8 cylinder 1964-1967,403 CID 6.6L L80 Oldsmobile V8 cylinder 1977-1979,260 CID 4.3L LF7 Oldsmobile Diesel V8 cylinder 1979,350 CID 5.7L Oldsmobile Diesel V8 cylinder 1978-1985.Clevite Tri-Metal 77 Connecting Rod Bearings combine the strength of a copper-lead alloy (Bi-Metal) layer with steel backing and an electro-plated Micro Babbitt metal as an overlay. Clevite Connecting Rod Bearing part number: CB684P10 (0.010in. / 0.25mm Oversize)The steel backing on the Clevite Tri-Metal 77 Connecting Rod Bearings provides strength and durability. The Bi-Metal Babbitt overlay provides the conformability and Load Capacity. The Third layer - Micro-Babbitt overlay provides the critical surface Embedability Conformability and has far more forgiveness than bi-metal. This ideal design has properties not found in many original equipment bearings. In most cases Clevite Tri-Metal 77 Bearings are an upgrade over a stock bearing, or three times better.It takes Three Layers to be Number One, and Clevite 77 Tri-Metal Bearings are it ! Engineering quality engine bearings involves a number of interdependent factors. Here is how Clevite 77s Tri-Metal cast copper lead material compares to bi-metal bearings on the most important of these factors:Seizure Resistance: Tri-Metal bearings have significantly greater seizure resistance than bi-metal bearings, by as much as 40%.Load Capacity: Tri-Metal bearings can withstand much higher loads for longer periods of time as compared to bi-metal bearings, over 60% higher loads.Embeddability Conformability: The overlay on a Tri-Metal bearing offers a far more forgiving surface than bi-metal bearings. This feature may not be as critical during OE a
