Special nut with an M22 x 1 mm thread for the sprocket shaft on various Tomos models (Quadro, Sprint, Classic, and FunSport).
It is common for Tomos engines to develop an oil leak at the sprocket shaft after some time.
This custom-made nut with an integrated shaft seal (commonly known as a Simmerring) solves this problem quickly and easily.
Simply replace the old nut with this one.
