| OK, so that large centre nut - the one with the long slot and the holes round the edges, that's supposed to turn is it? I've taken off the yoke and tried to move the centre nut and I can't move it. I was a little over zealous with the hammer trying to put it on first time, until I discovered the front brake trick. So I think skids is right and I've put too much pressure on the centre nut and hence on the head racers.
So how do I turn the centre nut ? |
