Description
4149 160 2902 STIHL Clutch Drum – Genuine OEM Part
The STIHL Clutch Drum (4149 160 2902) is a genuine OEM clutch drum designed for use on a wide range of STIHL trimmers, brushcutters, Kombi engines, hedge trimmers, and blower units. Serial number ranges apply on certain models (see compatibility list below).
The clutch drum works together with the centrifugal clutch to transfer engine power into the drive system. It spins when the clutch engages, allowing the cutting attachment or gearbox to operate smoothly. Replacing a worn, cracked, or damaged clutch drum helps restore proper engagement, reduces vibration, and prevents damage to related clutch components.
Manufactured to STIHL factory specifications, this OEM clutch drum ensures correct fitment, balanced rotation, and long service life.
