[alfa] Re: alfa-digest V9 #971 - Duetto Differential

[AlfaNeely@xxxxxxx]

       Could be either, depending on the design of the drain and fill plugs.  
Some drain plugs have a taper and require no gasket.  Those tend to be a 
simple plug with no lip.
       If your plug has a lip that presses against the housing, then it needs 
a gasket.  I have seen various plugs in various locations and I am not sure 
what the Duetto came with originally.  The plugs in the transmission will 
interchange with those on the rear end.  Or they will on the Bosch spiders.
       In general, the fill plugs on both the differential and the rear end 
of the later spiders require a 12 mm Allen wrench.  The drain plugs on both 
take a 17 or 19 mm socket.  Only the fill plug requires a gasket.  Again, it has 
been a while since I messed with a Duetto.
