During strip down of the drive actuator,have discovered from an old photo that this tubeular piece which you pull and twist has gone missing. most Atco’s have it but I don’t. Has anyone got a spare or is it a case of fabricate another bit. the inside diameter is 46 mm,and I am not sure how thick the sidewall is but I know if its to thick it will foul on the chaincase.
Also a couple of snaps of the chaincase and tank.
