The ball is captive in the tube attached to the lower pump body plate so nothing will come adrift when you remove the sump plate, gauze and gaskets....Take care not to overtighten the 1/4" nuts that hold the plate on when refitting...Ian
Thanks Ian , thanks for the info, that’s as I suspected as there is no mention of it on the oil change instructions pages I perused . Had a cracking if tiring 100 miles plus ride out on Saturday with the Pembrokeshire vintage and classic club , no problems to report except the heat and a sticky throttle cable 😁
