Clutch hub movement

Just installed my clutch hub and after tighten the APE nut with the torque washer and lock washer there is quite a bit of movement.... is this normal?
I have taken it on and off twice and cant see why?

I dont think there should be moment.
Took it all apart and the nut runs to the end of the thread..... used a rattle gun and moment?
help?

Right I have worked out what it is... its the steel insert in the clutch center.... how bad is this?

I had my clutch centre boss ground down, just about 10 thou thicker than the clutch hub centre. Helical cut primary gears make the clutch hub move in and out on the bearing.

Is this the problem?

If you have a steel insert in your hub and it looks like this then it's toast I'm afraid.

If it is indeed as UK GS NUT says (lateral movement and not the inner steel insert), you could try shimming it with the shims they used on the GSX1100 / GS1150 motors. They come in different thicknesses to solve the problem of lateral movement on the shaft and as stated above, caused by the fact that the helical primary gears are constantly trying to move the clutch from side to side.

And there is no need to panic too much. All these clutches make noise. The springs on the back of the primary drive plate rattle, the oil pump drives gear flaps about a bit (unless you have a fresh little rubber bung in there), the hub spacer is too large etc etc.

Just listen to one of those open Ducati dry clutches. They make a feature of all the rattling and people love it!
