Review on 🔧 89750516133 Echo Tool Clutch by Dennis Goozmer

Fits perfectly on my Echo CS-440 chainsaw's clutch, even though the description says 'fits CS400'. A quick look at the parts manual for both saws revealed that they use the same clutch, so I decided to take a chance. It doesn't fit perfectly as the 'teeth' don't press against the strongest part of the clutch, but I was able to apply the advertised 30Nm of torque without damaging anything. Please note that the coupling has left-hand threads and not all torque wrenches are capable of applying anti-clockwise torque. My Craftsman key fits, but the Tekton key I bought here at Revain does not.
