First time out on the 996 on Sunday since buying back in November last year.. long story!!.. noticed a metallic tinkling sound from the clutch when wheeling it back into the garage, removing the pressure plate confirmed it was the large, notched thrust washer that sits between the clutch spring posts tinkling away! I have not noticed this before, can anyone confirm if this is normal or maybe a problem??
Definitely not normal. That should be clamped in place by the large centre nut that holds the drum in place. Torqued to 220Nm if I remember right. Check that the drum isn't coming loose.
Hi, thanks, but this washer isn't clamped between the nut and the drum, it just sits over the nut and held in place by the notches for the spring posts! In the Haynes manual, there is no mention of it at all.. but is shown in the exploded assembly drawing!
If you are looking at the same parts list as me it is fitted under the bush (23 in the drawing) which is held down by the nut (25) and lock washer (5) and should not be rattling about.
Yes, that's the same parts list drg. now reading on.. I can see that this washer is removed after the centre nut and serrated washer! Weird because the washer is then shown being removed..but can't be seen in the previous photo when the nut is in place!! Will have to dismantle it tomorrow and have another look.. but the diameter of the washer definitely fits over the nut! Maybe I missed something! Will take some pics tomorrow when it is dismantled. Thanks for your help!
That large washer has a tendency to 'eat' into the (aluminium) hub underneath, so despite being tightened fully the hub can rattle around. You will see the entire hub/plates assembly lift slightly when you engage the clutch and if it does this then it will only get worse - mine actually had 'imprinted' perfectly into the hub so that it looked like it was meant to be like that and would lift enough for the spring caps to touch the inside of the clutch cover. You could fit another washer on top to clamp it down, or just replace the hub. If you get a billet aluminium hub you will save a lot of reciprocating weight and they seem to work just fine without the internal cush drives.
I will have to have another look tomorrow! One thing I didn't mention was that the pressure plate is a Ducati Corse billet item, not the diecast standard part, not sure that makes any difference! Nothing looked out of place, what confuses me is that the washer is too big to be held down by the centre nut and just rests between the spring posts. I will take pic tomorrow! Thanks for the advice!!
The washer should sit under the centre nut/washer, if not then it's either broken/worn or not fitted correctly...
Yes.. took it apart again tonight, I obviously didn't know what I was looking at!! The washer is just sat on top of the nut!!!! How someone managed to get that wrong is a mystery, will have to sort it! Anyone know if locking the drum in position with the bike in gear and brake on is easy enough to undo and torque up the centre nut??
Hmmm you might get away with it, but I doubt it unless it's loose, try either putting the back wheel against a wall so there's two points of contact or deflating the tyre a little and wedging a block under the tyre to increase the contact patch. Clutch holding tool is your safest bet and you'll need to repeat when torquing back up.
You really want a clutch holding tool (and not the £5 laser jobby from Machine Mart, because it's made of chocolate). Best way to undo it is with an impact wrench but it needs to be on there tight and you'll struggle to torque it up, plus you might damage something, without a holding tool.
I'm not far from Milton Keynes! I made a clutch holding tool from some 30mm x 5 steel bar, worked a treat!
Glad you found something that worked. I'm in High Wycbome and I've the proper clutch tool I could of brought up.
Thanks very much, appreciated! Only second time out on it today, a re-born again biker after far too long a lay off!! At least no bits fell off today!! Must remember to loctite everything!!
Ok...bugger!! On the way back from the Ride to the Wall, couple of weeks ago, a few miles from Lichfield, trouble changing down the box approaching a roundabout followed by a graunching noise and engine dieing!! Could see straight away that the tops of the spring caps had worked their way into the open aluminum clutch cover!! Obviously the clutch nut had worked its way undone!! Only got round to surveying the damage yesterday and other than the spring caps, no other signs of serious damage! Can only think I hadn't done the clutch nut up properly previously! Does anyone know if this is a common problem?? Any possible other damage that I can't see?? Should the serrated washer be replaced when removing the clutch? Any advice would be appreciated!
Happened to mine within 50 miles or so on the first ride out after having the cutch replaced (by a Ducati dealer!), that nut needs to be tight and they must have forgotten to do it properly - they told me that the 'O' ring had 'let go' The only damage to mine was the clutch cover that had been eaten through and the side fairing had a bite out of it where the clutch embedded into it...
Well that's what I thought but since they were repairing it FOC I couldn't be bothered to make too much of a fuss but I didn't go there again. :frown: I do my own maintenance now...
