• Description:

  This genuine Ford crankshaft main bearing is a precision engine-block bearing shell for the 5.0L Coyote V8 used in 2018-2024 F-150 and Mustang, cataloged by Ford as Bearing - Crankshaft Main under base number 6D309. It supports a crankshaft main journal in the block saddle and main cap, carrying combustion and rotational loads on a thin film of pressurized oil while holding the crank in precise alignment. Ford supplies this bearing in selective-fit grades, so the correct grade must be chosen from the crankshaft and block journal markings to achieve the specified oil clearance; verify clearance with the factory measuring procedure during assembly. Builders and technicians need this part during a rebuild, main-bearing knock diagnosis, or after low oil pressure, oil starvation, or contamination scored or spun a bearing. Symptoms of a worn main bearing include a deep rhythmic knock that rises with engine load, dropping oil pressure, and metal traces in the oil. Install the bearing with a clean, oiled running face, confirm cap orientation, and torque the main cap fasteners to the Ford specification and sequence. Using the engineered Ford bearing preserves crush, wall thickness, and material spec for reliable bottom-end durability.

• Notes: Includes 1 Upper Bearing And 1 Lower Bearing.
• Applications: 5.0L.
