The 3M2205H-STD from ACL is a high-performance main bearing set designed specifically for the BMC Mini Inline 4 engines produced from 1983 onwards. With a focus on durability and reliability, these bearings are crafted to meet the demands of both everyday drivers and performance enthusiasts.

Features

  • Constructed with a high-strength overlay plate that has a reduced thickness, enhancing fatigue properties and allowing for better performance under stress.
  • Hardened steel backs on all rod bearings provide robust support for the bearing lining, ensuring better retention within the housing.
  • Increased crush design enhances bearing retention, minimizing the risk of movement during operation.
  • Flash plating has been eliminated on the back of the bearings, which improves heat transfer and maximizes grip between the bearing and its housing.
  • Designed with increased eccentricity to accommodate bore distortion at high RPMs, aiding in the formation of hydrodynamic oil films.
  • Features 3/4 grooving on main bearings for optimized load-carrying surface area and improved oil flow to conrod bearings.
  • Tight and consistent wall tolerances help maintain the necessary clearances for optimal performance.
  • Enlarged ID chamfers on the bearing edges where needed to fit larger fillet radii commonly found on performance crankshafts.

Specifications
