Technical Details and Specifications

The Sealed Power 4-3545A rod bearing set is engineered to meet exact OE specifications for Ford 2.3L OHC L4 engines, commonly found in models such as the Ford Mustang, Mercury Cougar, and Mazda B2500. The bearings are constructed from A-series aluminum, providing a balance of strength and wear resistance. The set includes multiple sizes to accommodate standard and undersized shaft diameters, ensuring proper clearance and fit during engine rebuilds or repairs.

Key dimensional attributes include a housing bore diameter ranging from 2.1720 to 2.1728 inches and oil clearance tolerances between 0.0005 and 0.0026 inches. These precise measurements help maintain optimal lubrication and reduce wear on the connecting rod journals. The overall length of each bearing is 0.8000 inches, designed to fit the specified engine family without modification.

Applications and Problem Solving
