| To Da. {Bernard Day - Chassis Design} Rm {William Robotham - Chief Engineer} /JBD. {John B. Dixon - Fuel Systems} 4/JH.113.39. BENTLEY V SERVO SPRING PLATE. For the first 300 cars being released, will you please alter the drawing GB.4069 to a phosphor bronze plate .012 thick instead of .016". The overall depth of the plate should be altered to give a load of 4 - 6 lb. across the servo scissors to engage the friction disc. We attach a load deflection curve of this disc to fix the above dimension. The outer edge of the disc should be sealed with Heldite and adhesive tape.
