Description
Overview:
This flywheel is a Genuine Stihl part for FR130T and FS90 series machines, made from robust metal with an aluminium alloy body. It drives the ignition system and stabilises crankshaft rotation, helping the engine start reliably and run smoothly at idle and under load. The integral fan fins assist with cooling airflow around the cylinder shroud. Supplied to Stihl specification under MPN 4180 400 1200, it is a direct replacement for a worn, damaged, or cracked flywheel on a wide range of Stihl trimmers, brushcutters, Kombi engines, hedge trimmers, pole pruners, edgers, and earth augers. Using the correct OEM flywheel helps maintain correct ignition timing and reduces vibration, supporting long service life and consistent performance.
