We have established that a groove ball end pads improves the lubrication enormously. We should therefore like the ball ends on the shock absorber connections to be treated in this manner. The groove running half way across the pad from the blind end of the ball as explained to BY/SS.{S. Smith} c Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
