Description
Overview:
The 3A Dynamo Assembly for Yanmar diesel engines is a non-genuine replacement stator assembly designed to restore reliable power generation on small single‐cylinder engines. Built around a robust laminated steel core with copper windings, it includes an integrated permanent magnet and holder to produce stable charging output for the engine's electrical system. It is suitable for workshop repairs and preventative maintenance on Yanmar L‐series engines such as the L100 and L40. Engineered for a direct fit in place of OEM part number 114399-78730, it helps maintain battery charging, lighting and control circuits. Durable construction and a compact ring design with standard mounting points make it a practical choice where dependable electrical performance is required. Also referenced by manufacturer part numbers 320 and 330.
Key Features:
- Non Genuine Part engineered as a direct-fit replacement for OEM 114399-78730
- Complete stator assembly with integrated magnet and holder for consistent charging
- Durable laminated steel core and copper windings for long service life
- Designed for Yanmar L‐series housings with standard mounting points for straightforward fitting
- Stable output to support battery charging, lighting and control circuits
- Suits general service of engines used on site equipment and garden machinery
- Built to meet stringent quality standards for reliability in daily use
- Helps restore electrical efficiency on ageing engines with weak charging systems
- Compact, lightweight form factor for easy handling during installation
- Clear replacement choice where the original stator or magnet holder is damaged or worn
Typical Applications:
Used to generate electrical power on small diesel engines fitted to plate compactors, generators, water pumps, pressure washers, welders, lighting towers, tillers and other construction or garden machinery. Ideal when refurbishing engines that show poor charging, dim lighting or intermittent electrics. Suitable for both routine maintenance and full engine overhauls where the original stator assembly has failed.
Also known as:
Commonly referred to as a generator stator, alternator stator, magneto stator, charging coil, flywheel stator, rotor magnet holder, or charging assembly for Yanmar L‐series engines. These names describe the same component responsible for creating the AC output that is rectified or regulated to power and charge the engine's electrical system.
