Description
Overview:
This tapered crankshaft is a non-genuine replacement for Yanmar single‐cylinder diesel engines, including the L75 and L100. It is a precision‐machined steel component that restores smooth engine rotation by converting piston motion into rotational drive. The shaft features a tapered, threaded PTO end for secure mounting of hubs, pulleys or couplings, and is sized 147 mm (5.79 inches) from the cam gear face to the end of the shaft. Built for reliability in compact plant and garden machinery, it suits generators, pumps, plate compactors and other equipment using Yanmar L‐series engines. A 113 mm (4.45 inches) version is also available where shorter taper length is required. Use as a direct replacement when the original crankshaft is worn, scored, bent or otherwise unserviceable.
Key Features:
- Non-genuine, cost-effective replacement compatible with Yanmar L‐series engines
- Precision‐machined steel construction for durability and consistent running
- 147 mm (5.79 inches) taper length measured from cam gear face to shaft end
- Tapered and threaded PTO end for a secure, concentric fit of mating components
- Direct swap for worn or damaged crankshafts to restore performance and reliability
- Suitable for common small plant and machinery applications using L‐series diesels
- Supports regular maintenance schedules and reduces downtime
- Alternative 113 mm (4.45 inches) taper variant available where space is limited
Typical Applications:
Used in compact construction and garden machinery powered by Yanmar L‐series engines, such as generators, water pumps, pressure washers, plate compactors, small mixers and agricultural equipment. Ideal for rebuilds, preventative maintenance or repairs following bearing failure, oil starvation or impact damage.
