Centrifugal clutch plate (disc) for the STIHL 180 chainsaw, manufacturer EMAST, country of origin Taiwan. The clutch connects the engine to the chain drive sprocket only at working revs, so at idle the chain stays stationary.
Wear is indicated by a chain that rotates at idle or, on the contrary, slips under load, as well as vibration and unusual noise from the clutch. Before installing, inspect the springs and shoes and, if necessary, replace them together with the plate.
