  Bolt Bearing Cap Hex Head

• Description:

  This genuine Ford engine crankshaft main bearing cap bolt is the vertical fastener that threads down through the bottom of the main bearing cap into the block on the 5.0L Coyote V8, providing the primary vertical clamp load that holds the crankshaft main bearings and caps in precise alignment. It is a 9 x 87mm hex-head bolt that threads through the bottom of the main bearing cap, and it fits 2011-2025 Ford 5.0L Coyote V8 applications including Mustang GT and F-150 5.0L. The Coyote deep-skirt block uses three distinct fasteners in the base 6345 family to secure each cap, and this bottom-entry bolt works together with the main cap stud and the side cross bolt to fully clamp the girdle. A technician needs this bolt during a short-block rebuild, main bearing service, crankshaft replacement, or whenever a cap bolt was over-torqued, stretched, corroded, or damaged. A yielded or reused bolt cannot maintain correct clamp load, which risks bearing crush loss, cap movement, and bearing failure. This is a single-use torque-to-yield fastener: never reuse it, always install a new bolt and torque it to Ford's exact multi-step angle specification with the specified thread lubricant, as reusing a stretched fastener can cause loss of clamp load and severe engine damage. Cataloged by Ford as the Engine Crankshaft Main Bearing Cap Bolt. Backed by the Ford genuine parts warranty.
