Hydraulic clutch hose thread?
- Thread starter cape
- Start date
The union at the clutch end must be screwed tight to the bottom of the threaded hole, not sealed at the cover with a copper washer. This prevents fluid from escaping between the cover itself and the pressed-in hydraulic cylinder, which can cause the cover to fail. This is in fact a factory design flaw... Luigi strikes again!
The early hydraulic covers have a pressed-in cylinder, old contaminated fluid that gets between cover and cylinder can(will!) cause corrosion, which can severely weaken the cover.
The later 120?-type covers do not have the pressed-in cylinder, these can safely be sealed with a copper washer.

Thanks for the insight Piet, good info.
Interesting thing about the old hose, there is a reference ?Brembo 06/82?, so it would have been manufactured July/82. That would indicate that the hose was renewed at that early stage. If so, I wonder why? Or it's been renewed later and the hose was just old stock. Or would the bike itself actually be -82 model? According to laverdamania register my bike #7564 is -81 model and bikes from #7947 forward are -82. Is there any record about clutch renewals made under factory warranty?

More than likely IMHO!

None that I know of.
Perhaps the hose was chafed somewhere and replaced as a precaution. Or the bike was cannabilised (more likely!
) for spares at some point. Do you have any record of when the bike was first sold? Not unusual for them to have grown roots in the showrooms for a few years... Can't imagine 180s being manufactured after 1981, the factory probably concentrated on the interim model Jota 120 and the RGS by then.
