VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1933-1936 distributor on 34..35

hello.... so it seems to me that a 34 and a 35 standard moter had two different style distributors eg the 35 has a differant points setup...but are they interchangeable ???
can I use a 34 dissy in my 35 ???
...would the gearing be differant ??are they the same as a 36???
just asking cos Im interested....
......dave...........

All distributor gears are the same 1929 to 1936.

From my 1950 parts book,

1933/1934 CA , CB, O, DA , DB can use 644-R distributor ( a 644D was the original in 1933)
1935, all, can use 645-G
1936, 645-T

ok..jack...so the 35 dissy was a one off ???
are the interchangeable..??
interesting..dave..

You will find that there is different vacuum , and automatic advance curves from one year to another. Fitting a different year dissy would require measuring the lengths of the shafts to ensure correct meshing of the oil pump and camshaft drive gear.

The vacuum advance canisters could also be different , so would need to be checked for fit.

The 1936 distributor is the first year for the male oil pump drive tang, the previous years where female (fork) on the oil pump drive end.
