Suitable for flywheels, magnetos, magnet wheels, ignition flywheels, rotors, fan wheels and accessories for Husqvarna 394 and 395 petrol chainsaws.

The flywheel is a crucial component of a chainsaw engine. It provides mechanical inertia, ignition, and cooling. In high-performance professional chainsaws like the Husqvarna 394 and 395, its function directly affects engine operation, ignition timing, and heat dissipation. A damaged flywheel can lead to problems such as starting difficulties or failure to start (magnet defect or misalignment), excessive vibration during operation (dynamic imbalance), insufficient cooling (damaged saw blades), or metallic noises (worn or loose keyway). This flywheel was specifically designed for the high-performance Husqvarna 394 and 395 chainsaws and is precision-machined from high-strength alloys. Its robust structure with intact cooling fins ensures a powerful airflow. The internal magnets are made of a high-energy material and generate a strong and stable magnetic force for optimal ignition and a powerful spark. The flywheel undergoes rigorous dynamic balancing tests to ensure smooth operation at high speeds with minimal vibration, effectively protecting the crankshaft and bearings. The installation dimensions and keyway position precisely match the original specifications. Simply replacing the damaged flywheel restores normal engine operation. This high-quality replacement part provides a reliable repair solution, restoring smooth running and optimal performance to your professional chainsaw. During installation, ensure that the conical surfaces of the flywheel and crankshaft are clean and free of foreign matter, that the keyway and semicircular fit are correctly aligned, and that the locknut is tightened to the specified torque to guarantee safe operation and a long service life.
