This Genuine Stihl clutch assembly is a key drivetrain component for professional and heavy‐duty chainsaws, including the Stihl MS440 and MS460. Built from high‐strength metal for long service life, it uses a centrifugal design to engage the chain drive under throttle and disengage at idle, helping the saw start cleanly and run safely. As an OEM part (1128 160 2004), it offers a direct fit and correct operating characteristics without adjustment. Replacing a worn or slipping clutch restores smooth pick‐up, consistent cutting performance, and protects other transmission parts from excessive wear. Suitable for forestry, arborist, and grounds maintenance tasks, this genuine assembly keeps your saw dependable across demanding jobs and variable loads commonly encountered on 044/046 platform machines.

Key Features:
– Genuine Stihl part for assured compatibility and performance
– OEM reference 1128 160 2004 for precise fit on specified models
– Robust metal construction to withstand heat, friction, and high rpm
– Centrifugal action for smooth, predictable chain engagement at working speed
– Helps cure slipping, slow take‐up, or overheating caused by worn components
– Precisely machined for reliable operation and reduced vibration
– Direct replacement using standard workshop tools, no modifications required
– Supports safe idle disengagement to reduce chain movement when not cutting
