C16786-UK TWO UPGRADED Load Spring Belleville washers for mechanical PTO clutches used on all 200, 400, 600 series Case Ingersoll Machines. These are OUR UPGRADED washers we have custom sourced as they are heavier duty and provide a little bit more engaging force as well as retain their spring/pressure force longer for longer replacement intervals. Both shim adjust and EZ adjust clutch Set ups. These apply pressure and give you the resistance and "clicks" when engaging PTO lever. These have a life and do fatigue. If your clutch is slipping or not staying engaged and is adjusted correctly. These are likely your issue.
