Does anyone know if the 16 tooth gear on a 1967 4 speed unit 650 triumph transmission is replaceable?
I see the part number for the mainshaft with gear before DU48144 is 57-0914 and is costly and after that engine number it is 57-2436. What is the change that took place between these two?Please let me know if anyone knows of a somewhere i can order just the gear if its replaceable.
Thank You
