KOMATSU D20 D20A D21 D21A
|We have made BIMETALLIC BRONZE friction discs
and steel separator plates, for the D20, D20A, D21, and D21A steering clutches.
Quantities required are based upon your model, serial number, and the condition of your clutch. There were also two sizes of steering clutches in these machines. The earlier clutches had larger diameter clutches and discs. (9 1/8" or 231 mm for the lined disc) (8 5/8" or 220mm for the steel plate) The later clutches had the small clutch discs. (7 15/16" or 202mm lined friction discs) (7 1/2" or 190 mm steel separator plate)
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 dollars.
