Description
Overview:
This Genuine Stihl flywheel is an OEM replacement for selected handheld and backpack machines, including the BG86 and BR200. Manufactured from durable cast aluminium alloy, it is designed to rotate with the crankshaft, store rotational energy, and drive cooling airflow across the engine fins. The embedded magnets work with the ignition module to time the spark, helping the engine start cleanly and run smoothly. It is a direct-fit part for compatible Stihl leaf blowers, shredder vacs and mistblowers, restoring performance where the original flywheel is worn, cracked or damaged. Supplied under Stihl MPN 4241 400 1200 for precise identification, this component maintains reliability and efficiency while keeping vibration and engine temperatures under control during everyday use.
Key Features:
- Genuine Stihl OEM part for exact fit and dependable performance
- Cast aluminium alloy construction for strength, low weight and corrosion resistance
- Finned rotor profile to aid engine cooling airflow during operation
- Integrated magnets for correct ignition timing and reliable spark generation
- Precisely balanced to help reduce vibration and improve smooth running
- Direct replacement using existing fasteners and starter pawl arrangement
- Helps cure issues from damaged flywheels or sheared keyways affecting timing
- Engineered for Stihl platforms used in blowers, vacs and mistblowers
- Marked by MPN 4241 400 1200 for easy parts identification
Typical Applications:
Used during routine servicing or repair of Stihl machines when the original flywheel shows impact damage, cracked fins, excessive wear, or timing issues. Suitable for restoring easy starting, stable idle and consistent power in professional and domestic environments, including landscaping, grounds maintenance, facilities care and seasonal leaf clearance.
Also known as:
Engine flywheel, magneto flywheel, ignition rotor, magnet rotor, flywheel rotor, blower flywheel. These terms refer to the same rotating component that stores energy, drives cooling airflow and triggers the ignition system.
