Gearbox shifter drum

(1/2) > >>

Pauarc:
Does anyone know how to check if this shifter drum is the early one or later one as I can’t find any identification number on it it’s from a k2 engine

Johnny4428:
That looks to me like the later modified drum. The reason I say that is that the modified ones had a wider point where the gears were in the midst of changing. That is explained very poorly but I have a photo of the one that came out of my K3. Modified to give smoother change between gears as far as I’m aware.

Nurse Julie:
Agree, later type.

Bryanj:
I thought there was a bulletin on that in alladins cave which had pics on it

Bryanj:
