Just repairing my domestic water pump (on tank water), $6.50 bearing crapped out. Idiots used z type seal and they get contaminated from ants moving stuff around. Now got 2RS fitted. Cheap arse European company.
Anyway as I pulled the thing apart I got to the mechanical seal. It looked familiar. Yep Ducati desmoquattro seal. I have an original in a packed still. They changed pump seal design some time after the 89/90 model. Side cover is not the same.
So save yourself some cash if you have the later style and get a 12mm mechanical water pump seal.
