Clutches - Bentley and 20/25. ---------------------------- We have experienced rapid wear on several Bentley Clutch linings due to the edges of the staggered portions of the friction plate being chamfered, leaving a sharp edge, and not radiused. A radius is shown on the drawing, and this should be adhered to. As this trouble may also happen on 20/25 Chassis, we suggest a Depot Sheet be sent out so that this point can be attended to when clutches are dismantled. He/H.{Arthur M.
