Description
Overview:
This crank is a replacement engine component for Husqvarna K950 and K950 Rescue disc cutters. It converts the piston's up-and-down motion into rotary drive and is central to smooth running and power delivery. Built with durable metal construction and precision-machined surfaces, it is designed to cope with high engine speeds and the demanding loads of two-stroke petrol cutters. The geometry and threads match the original specification for a straightforward fit during an engine rebuild. When installed with good bearings and seals, it helps restore performance, reduce vibration, and support long service life. A suitable choice when addressing wear, scoring, or damage from bearing failure, it ensures reliable alignment with mating parts such as bearings, seals, clutch, and flywheel on the specified models.
Key Features:
- Direct-fit replacement for Husqvarna K950 and K950 Rescue engines
- Precision-machined running surfaces for smooth, efficient operation
- Robust metal construction suited to heavy-duty site conditions
- Balanced design to support high RPM and minimise vibration
- Works with standard bearings, seals, clutch, and flywheel for these models
- Helps simplify engine overhauls using typical workshop tools
- Model-specific dimensions for reliable sealing and alignment
- Suitable for demanding cutting environments across construction and rescue work
Typical Applications:
Used during engine rebuilds or repairs of Husqvarna K950-series disc cutters in construction, demolition, utilities, and emergency services. Replace when the original crank is bent, scored, seized, or exhibiting excessive play, or following bearing failure. Helps restore starting, idling, and cutting performance and extend machine life.
