Description
Overview:
The Genuine Big End Bearing for Yanmar single‐cylinder diesel engines supports the crankshaft at the connecting rod, controlling oil clearance and reducing friction under heavy load. Built as a steel‐backed bearing with a precision bearing alloy surface, it is engineered for strength, heat resistance and consistent lubrication. This part keeps the crankshaft running true, helps prevent scoring and knock, and restores smooth operation after wear. It is a direct OEM replacement for Yanmar applications and is suitable for engines used in compact construction plant and garden machinery. Genuine Yanmar part MPN: 114940-23600. Ideal for routine servicing or full rebuilds on models such as the L75 and L100 where reliability and long service life are critical.
