We have had both dry clutch discs and oil type clutch discs produced, both friction discs and steel separator plates, for the D30 D31 D30A AND D31A D31Psteering clutches.

Quantities required are based upon your model, serial number, and  the condition of your clutch.

Check your clutches closely.  You can often get by with only replacing the friction discs.  Use your best judgment for evaluating your steel plates.  You do not want to install plates that are rough and will accelerate the wear on your new fiber discs.  Clean them with wire brushes, sandblasting, or whatever it takes to get them as smooth as possible and then make your decision.  It is up to you of course, but unless you just like to pull wrenches, these steering clutches are not that much fun to have to remove and reinstall because you tried to save a hundred dollar bill.
