Description
Overview:
These Big End Bearing Shells are non-genuine replacements for Yanmar L‐series single‐cylinder diesel engines, including L75 and L90. They are designed to replace OEM part number 714650-23600. The shells are steel-backed with a durable bearing alloy running surface and are precision finished to support the crankshaft journal and maintain the lubricating oil film under load. Used across compact construction and garden machinery, such as generators, pumps and plate compactors powered by these engines, they help restore smooth, efficient operation when original bearings are worn. The semi-circular shells seat in the connecting rod and cap to provide correct support and low-friction rotation at the big end. For reliability, always assemble with clean parts, correct torque, and adequate assembly lubricant. Note: these shells are not compatible with genuine Yanmar connecting rods.
