I have just obtained a reconditioned dynamo and need fasten the sprocket on.
The nut which holds the sprocket on is a bit stiff, so when I attempt to tighten it, it breaks the sprocket taper and the dynamo turns.
I can get the nut on by about 1.5 turns before this happens.
Does anyone ave any idea how to keep the dynamo static.
I notice two slots on the ring at on the end of the armature under the sprocket, are these or a special tool?
Any help greatly appreciated.
