X8300 We have tested the original type gravity clutch brake sent through for this clutch in order to make it stop more readily. At the same time we ground the ball races so that they would allow the joint to float. We find that the clutch still does not stop definitely. We are therefore fixing a spring inside the clutch as suggested by you. MADE AT CROXLEY Hs.{Lord Ernest Hives - Chair} | ||
