Does anybody have the info or know of a site that identifies Lucas magneto's, which bikes they were applicable to and the proper rotation of said mags?
I've got a Lucas mag 42453A made in 1964. This mag came on my '54 Tiger 100 when I bought the bike. Bike really didn't want to run with it...so I changed magneto's...it runs...using mag K2F 42344A.The latter mag has the arrow missing from the tag for direction of rotation (clockwise-anti-clockwise) but since the bike runs I'll assume it is correct
The direction of rotation for the K2F 42453A mag is clockwise from the drive end (according to the arrow). I also with some limited research have been able to identify this mag as used on AMC, Norton, Matchless bikes. I'm pretty sure all Triumphs used a anti-clockwise rotation mag. Someone please correct me if I'm wrong.
Also, is it possible for the home mechanic to change the slip ring (to anti-clockwise slip ring) if that's only as far as I go?
I just sold the 42453A magneto. It's history!!! My 1960-1962 Triumph B range replacement parts catolog also lists 42344 as the magneto for T110 and T120 with blanked off manual advance. My 42344A mag was made in 1955 and is blanked off as well. It works fine.
