Description
Overview:
This Flywheel is a genuine Stihl OEM component for mistblowers and backpack blowers using the relevant engine platform, including SR 430 and SR 450. Manufactured from durable aluminium alloy with a precisely machined hub, it stores rotational energy to stabilise engine speed and maintain smooth running. The flywheel also works with the ignition system to support accurate timing, helping the engine start reliably and run efficiently under load. Supplied to OEM No. 4282 400 1200, it is a direct-fit replacement for worn, cracked, or damaged units and restores correct balance and operation. Suitable for professional and domestic users, it is a dependable choice for routine servicing where factory specification and compatibility with Stihl machines are required.
