TR2/3/3A TR3A Lucas Distributor

[angelfj1]

Can someone tell me if more than one style/model number Lucas distributor was used in the 3A model.

Thanks

Frank

According to the Lucas Master Catalogue, several different part numbers ultimately superceded to 40698, which was a model DM2P4.

I also have 40480 listed as original for 56-59 TR3; and 40783 as a "universal replacement" for TR2-3A. Several more numbers listed for TR3B through 4A.

40480 (in several variations) is one of the numbers ultimated superceded by 40698.

The complete list from my 1960 Lucas Master Catalogue 400E:

*40403A/D; 1954-56
*40480A; 1956
*40480B/E; 1957-58
*40480F; 1959
40698A; 1960
40698B; Later 1960 (NOTE: all model DM2P4; * indicates superceded)

From Lucas Popular Spares 1962-71, catalogue 725EX

40795; TR4 1962-67 (NOTE: model 25D4)

From Lucas....1963 Standard and Triumph, catalogue CCE 902/63

[for Triumph TR4 2/3-seater Sports Car]

40735A; 86mm engine (NOTE: model DM2P4)

Andy, Randall: thanks much!

As I'm sure Andy knows but others might not; the different suffix letters indicate that the specifications remain the same, they are functionally identical; but the internal components may have changed slightly (or just be from different sources).

Randall, thanks for spotting those typos; I have corrected my post above for future reference by others. (Sometimes it's difficult to type with a cat on my lap!)

More minutia about the model numbers: "D" simply refers to a distributor; "M" refers to micro control; "P" refers to a porous bushing; and "4" means suitable for four-cylinder engines.

Meow. :wink:
