RE: [alfa] Transmission drive flange nuts

["Jeff Greenfield" <alfaguy@xxxxxxxxxxxx>]

John - 

Is the nut the same part number throughout?

The tab washer (lock tab) makes sense, can't say I've ever seen one as all
the cars I've seen have been worked on by many over the years so it is hard
to know what was really original.

I can't imagine the nut as used on the later (2L and up) cars, would be the
same as what was used on the earlier cars with the tab washer though ...
kind of a belt and suspenders kind of thing, no?

As always, thanks for your insight ...

Jeff

<FWIW, the books show a single nut and a tabwasher ('rondella di
sicurezza') for the earlier cars, and no tabwasher for the 2000. The
tabwasher carried a 102 part number (102.00.13.406.01) through the early
1750 parts books, thus dates to the original development of the
split-case design. The later (1974) Catalogo Rapido gives a 105 part
number (105.48.13.306.00), suggesting that the washer was redesigned
during the production run of the 1750 Berlina.>
