SP-CLUTCH DRUM STIHL (MS-180)
Clutch drum for the Stihl MS‑180 chainsaw.
Connects the engine’s crankshaft to the chain sprocket, transmitting rotational force when the clutch engages.
Made of hardened steel to handle friction, rotational forces, and wear.
Designed to fit the MS‑180 model or compatible Stihl chainsaws with the same chain pitch.
Uses / Advantages:
Transfers engine power to the chain only when the clutch engages, allowing the chain to remain stationary at idle.
Ensures smooth and efficient cutting performance.
Helps maintain proper chain tension and reduces slippage or uneven motion.
Replacement restores performance and safety for worn or damaged chainsaw drive components.
Limitations / Notes:
Must match the MS‑180 or compatible models exactly; incorrect drum can cause chain problems or damage.
Inspect for wear: worn grooves or rounded sprocket teeth indicate replacement is needed.
Often replaced along with clutch components, bearings, and washers for optimal performance.
Proper installation is important: clean the crankshaft stub, grease bearings, and ensure alignment to prevent vibration or premature wear.
