I'm after some advice on how to correctly reassemble the front free wheeling hubs on a 93 Feroza. (Yes Murcod, its getting put back together

Is this normal. Will they only unlock once the wheel is spinning at speed or should they unlock reguardless of wheel speed. The problem seems to be that when I turn the dial to the unlock position, nothing is pulling the clutch inside the hub to the disengaged position. I am thinking perhaps i'm installing a spring wrong.
Anyone else had a similar problem?
Thanks
Dave.
