Product Details

The King Engine Bearings CR 691SI0.75 is a precision-manufactured connecting rod bearing set designed for the Ford V-6 183 cubic inch (3.0L) engine. This set is sized at +0.75mm undersize, making it suitable for engine rebuilds where crankshaft journals have been reground to the 0.75mm undersize specification.

Constructed using King's Silicon Aluminum Bi-Metal (SI) material, these bearings feature an aluminum-based alloy strengthened with 2.5–3% silicon content. This construction is engineered for medium load engines and is particularly well-suited for use with nodular cast iron crankshafts, delivering a reliable balance of conformability, embedability, and load capacity.

Key Features:

  • Material: Bi-Metal Silicon Aluminum (SI) — aluminum alloy enhanced with 2.5–3% silicon for improved strength
  • Size: +0.75mm undersize for reground crankshaft journals
  • Bored finish for precise dimensional accuracy and consistent oil clearance
  • Designed for medium load applications and compatible with nodular cast iron crankshafts
  • Manufactured to tight wall-thickness tolerances for shell-to-shell consistency
  • Full connecting rod bearing set included

King Engine Bearings are produced entirely in-house, from alloy casting through finished packaging, ensuring rigorous quality control at every stage of production. The CR 691SI0.75 is an ideal choice for professional engine rebuilders and DIY mechanics restoring the Ford V-6 183 to proper specification.
