Distributor Clutch
The distributor screws are driven by a friction plate, keyed to the distributor clutch shaft, and held against the face of the distributor driving pulley by a spring inside of the distributor clutch flange. This allows the clutch to slip when anything binds the distributor screws.
The clutch shaft, operated by the friction plate, drives the distributor screws by means of small gears which are timed so that the matrices will hang perpendicular from the distributor bar.
To remove the distributor clutch, loosen the small screw on the distributor clutch lever, and remove the clutch rod, spring, and lever. Remove the hexagon head machine screw that holds the clutch bracket to the distributor beam. Insert a screw driver between the bracket and the beam at the upper end and pry the bracket away from the beam. Lift the bracket off over the end of the shaft. Remove the screw in the washer on the end of the clutch shaft. Take out the spring which is behind the washer. The friction plate and pulley can then be removed over the end of the shaft.
The friction plate should be kept free from oil at all times. There is an oil hole in the flange of the pulley which should not be overlooked when oiling. This hole should be kept stopped with a counter sunk screw to prevent the oil working out on the drive belt.
