MICHIGAN 77 CB684P10 P-Series Connecting Rod Bearing Undersize - 0.010

The MICHIGAN 77 CB684P10 is a high-performance connecting rod bearing featuring P-Series tri-metal construction designed for demanding engine applications. This bearing is manufactured with a 0.010 inch undersize specification, making it ideal for crankshafts that have been ground to remove wear or damage.

Advanced Tri-Metal Construction:

• Hardened steel backing layer provides exceptional strength and durability
• Copper-lead alloy intermediate layer offers superior load-carrying capacity
• Electroplated babbitt overlay delivers critical surface characteristics including conformability and reduced friction
• Tri-metal design supports maximum loads up to 12,000 psi

P-Series Performance Features:

• Higher eccentricity and crush factor compensate for rod bore distortion in high-RPM applications
• Extra-thin overlays optimize oil film characteristics
• Dowel holes in lower sections accommodate aluminum connecting rods
• Suitable upgrade from bi-metal bearings due to increased load capacity

Applications: This bearing is compatible with Checker, Chevrolet, and Oldsmobile V8 engines (both gasoline and diesel). The P-Series is ideal for engine rebuilds where more demanding use is anticipated, including heavy-duty applications, motorsports, street performance, and high-revving engines. As the most versatile replacement bearing in the Clevite 77 performance bearing family, it serves as a suitable direct replacement for most OE applications.

Note: This bearing is sold individually and features 0.010 inch undersize dimensions to match crankshaft journals that have been machined undersize. Proper measurement of crankshaft journals and oil clearance verification is essential during installation.
