Lambretta O Ring, 12 x 2.75mm oversized for gear selector arms, MB
MBB0130
Standard 12 x 2.5mm O rings for the gear selector arm shaft and the clutch arm are sometimes a little too small and can leak.
Try an oversized 3mm version and they can be too tight.
This MB 12 x 2.75mm inbetween version usually works perfect and stops leaks.
