BRONZE CLUTCH CONVERSION, WITH 5 HI-TORQUE BRONZE PLATES

THE STANDARD BRONZE CLUTCH PLATE INTRODUCED BY NORTON ON THE 850 5 FRICTION PLATE SYSTEM WAS INTRODUCED IN AN ATTEMPT TO SOLVE OIL IMPREGNATION PROBLEMS THAT OCCURRED WITH THE FIBRE CLUTCH PLATES UNFORTUNATELY THE DESIGNERS SIMPLY COPIED THE DIMENSIONS OF THE FIBRE PLATE WHILST USING A MUCH HARDER MATERIAL, THIS ERROR RESULTED IN A CLUTCH PLATE THAT DID NOT WEAR.  CONTROLLED WEAR IS NECESSARY IN THIS SORT OF ENVIRONMENT BECAUSE IF NO WEAR OCCURS THE SURFACE SIMPLY BECOMES POLISHED AND GLAZED THUS LOSING ITS ABILITY TO GRIP.  OUR BRONZE PLATE USING THE FRICTION MATERIAL CONCENTRATED TO THE PERIMETER DOES NOT SUFFER FROM GLAZING AND HAS A FURTHER ADVANTAGE IN THAT MOVING THE CONTACT PATCH AWAY FROM THE CENTRE ALLOWS THE PLATE TO DELIVER MORE TORQUE AND ELIMINATES CLUTCH SLIP.

BRONZE CLUTCH CONVERSION.  CONSISTING OF:

063741 - BRONZE CLUTCH PLATE 3.2mm THICK X5
063768 - STEEL PRESSURE PLATE X1
HS0746 - STEEL CLUTCH PLATE 2mm THICK X1


The 050008 clutch kit is supplied with 5 new bronze plates and a new pressure plate and only one steel plate, the reason we only supply one steel plate is if you are replacing the fibre clutch plates you would already have 3 steel plates in that clutch arrangement and these can be reused with the bronze plate as long as they are flat and in good condition. If you were starting from scratch then you will need to purchase an additional 3 plates and we would recommend 3 of the HS0746.
