  Bearings, Thrust Bearing, Bearing Crankshaft Main

• Description:

  This genuine Ford crankshaft main bearing supports the rotating crankshaft inside the engine block, maintaining the precise oil-film clearance needed for proper lubrication, rotating-assembly alignment, and bottom-end durability. It is built to Ford's selective-fit grading system, so the correct bearing must be matched to the block and crankshaft grade stamped on your engine to hold the right clearance. This bearing fits the 5.0L and 5.2L Coyote-family V8 engines used in the 2011-2020 Ford Mustang, the 2011-2017 Ford F-150, and the 2011-2014 Lincoln Mark LT. Engine builders and machine shops reach for this bearing during a bottom-end rebuild, a rod or main bearing knock diagnosis, or after a low oil-pressure event that scored the original bearing surface. Warning signs that point to worn main bearings include a deep rumbling or knocking noise from the bottom of the engine that changes with RPM, low oil pressure readings, metal flecks in the oil, or excessive crankshaft end play. Ford's catalog lists this part in the crankshaft main bearing family, distinct from the thrust bearing that controls end play; verify the selective-fit grade for your specific block before final assembly. Because main bearings are a wear item sized to a specific clearance, do not reuse a bearing that shows scoring, bluing, or measurable wear, and always check clearances with plastigauge or a micrometer during installation rather than assuming factory numbers still apply.

• Notes: Includes 1 Upper Bearing And 1 Lower Bearing. Includes One Standard Upper And Lower Bearing.
• Applications: 5.0L. 5.2L.
