King Engine Bearings Mercedes Benz Om611.960/981/Om646.821/962/966 (Size +0.25mm) Conrod Bearing Set

This set includes connecting rod bearings from King Engine Bearings, specifically sized at +0.25mm. These bearings are built for Mercedes-Benz engines like the OM611.960/981 and OM646.821/962/966. They feature a strengthened trimetal construction, designed to handle the demands of these engines.

When rebuilding or repairing an engine, especially one with higher mileage or performance modifications, replacing the connecting rod bearings is a critical step. These bearings sit between the connecting rod and the crankshaft journal, allowing for smooth rotation while handling significant loads. The trimetal design offers a good balance of strength and conformability, helping to maintain oil film and reduce wear.

This set is specifically sized at +0.25mm, meaning it's intended for use when the crankshaft journals have been machined down by 0.25mm to correct for wear or damage. Always ensure your crankshaft journals are properly measured and machined to the correct size before installing oversized bearings.
