BENTLEY AND 20/25 HP. CHASSIS - CLUTCH. --------------------------------------- In view of the fact that we are still getting odd cases of clutch pressure plates cracking on the inside rim, By.{R.W. Bailey - Chief Engineer} suggests that the inside diameter of the pressure plate is decreased by .200" in order to increase the thickness of the inner rim by .100, therefore will you please issue instructions to the Works accordingly. The alteration should, of course, apply to both Bentley and 20/25 HP. chassis - cast iron pressure plates only. BY.{R.W. Bailey - Chief Engineer} By | ||
