Description
Overview:
This tapered crankshaft is a non-genuine replacement part for Yanmar single-cylinder diesel engines, built for generators and other stationary equipment using a tapered output. Made from durable steel with a precision-machined finish, it restores smooth running and reliable power transfer where the original crank has worn or failed. The tapered portion measures 119 mm (4.69 inches) for accurate seating of compatible generator rotors and couplings. Suitable for Yanmar L75 and L100 series engines (and others listed below), it supports dependable starting, steady load handling, and extended service life when installed and maintained correctly. Manufacturer Part Number (MPN): 320 225. A practical, cost-effective option for keeping vital plant and power equipment in service without compromising on fit or function.
Key Features:
- Non-genuine replacement for cost-effective maintenance without sacrificing usability
- Steel construction with precision machining for consistent performance and fit
- Tapered section length 119 mm (4.69 inches) for generator-focused applications
- Designed to suit Yanmar L-series mounting and drive geometry where a taper is specified
- Supports smooth operation, reducing vibration and wear on mating components
- Suitable for demanding site conditions and continuous running duty
- Compatible with common generator couplings and rotors used on listed engines
- Straightforward replacement when following standard engine service procedures
Typical Applications:
Engine rebuilds and repairs on generator sets powered by Yanmar L-series engines, including site power, standby and backup generators for workshops, farms, and small businesses. Also used in fixed installations where a tapered crank is required for direct coupling to a generator rotor or compatible drive hub. Ideal for restoring output stability, improving reliability after bearing or journal wear, and extending the service life of equipment.
Also known as:
Crank, engine crank, crankshaft, tapered crank, engine shaft, crank spindle, crank axle, drive shaft (engine), rotor drive shaft, Yanmar L-series crank.
