Description
Overview:
This Tappet Assembly, Roller is a genuine Yanmar component for L‐Series single‐cylinder diesel engines. Built from hardened steel with a precision‐ground roller, it transfers camshaft motion to the valve train while minimising friction and wear. Supplied under Manufacturer Part Number (MPN) 114210-14300, it maintains correct valve timing and smooth running, supporting reliable starting and consistent operation under load. Designed for compact industrial engines such as the Yanmar L100N and L70N, it is a direct replacement for worn or damaged tappets during servicing or overhaul. The robust steel body and captive roller pin are engineered for long service life in demanding environments, helping protect associated parts such as cam lobes, pushrods and rocker gear by ensuring controlled contact and stable valve actuation.
