G'Day folks,
Zooming down the road the other week, when I noticed it starting to over-rev in top gear when I tried hard acceleration. Since then this now happens in every gear. Is this the dreaded clutch slip?!! If so, has this been expensive in anyone's experience? Can I alleviate the problem by cleaning the gunk out from under the clutch cover? Should I ventilate the clutch cover? - So many questions. I would like to hear from anyone who has had a similar problem. Panic is setting in.........

I did have exactly the same symptoms on my Gilera last year.
Cleaning the clutch assy will be good, but not help. I`m about sure that your clutch discs are worn.
Removing them is not very difficult. Refer to the workshop manual in the download section.
Drivng plates (the ones with friction material) should not be under 00,11 in. (2,8mm). Distortion laying them on a flat surface should be below 0,008in. (0,2mm)
Clutch springs should not be shorter than 1.456in. (37mm).
I couldn`t find the info about min. thickness of the metal discs.
If you remove the discs write down the exact order and rebuild it as it was.

For a minimal ventilation you can put washers under the cover so there`s at least a little gap between engine and cover. I guess 2-3mm washers should be possible without the clutch piston popping out of its place.

AND those metal plates WITHOUT friction material MUST be flat. I mean now, that if they get hot, then they start to be little blue coloured and bent then and then U have to throw them away! There is also one, or two curved plates marked by small dot, so remember to put those dot sides, as they were there, remembering outwards...

The clutch pack is worn out. I wouldn't ride it anymow until it's fixed. Letting the clutch slip overheats the pressure plate and other metal surfaces.

Ian, Your clutch plates seems to "slip" and surely then U need new plates, but check carefully all plates, if need all new plates, or only those friction plates. Check also, if any oil is in clutch assy!!! If there is oil, then You have to make bigger job with gaskets between case and clutch and no any need to put new plates to clutch, before U have found/fixes oil leak.... Btw, those STM clutch systems are very good, but more expensive, than normals...

which STM clutch model fits in the P750/906 or are you mixing that up with your 907ie ?!

G.

..remembering, that 750 have exact same basket, as 907IE.... Go for 48 teeths, what is much better, than normal 12 teeth...

so you combine STM clutch basket and discs with original pressure plate ?
If I remember well all STM clutches I`ve seen were for clutches activated from the other engine side, not from the clutch cover.
Any model numbers ?
I need details this is interesting.

G.

I cant remember just now exact differences between 750 and 907 pressure plates, but i think You can use normal pressure plate with STM 48 teeth basket & plates without any difficulties, like i use also in my 907 just now. My 750 have still original clutch assy, so dont know exact that, cause no need yet to change plates....

I have already one set of red STM 48 basket and plates ready to put to my ST4S, when need to change new plates to her. Ill keep 750 still, like stock.

In this set read:

ALL plates: Clutch plate kit for Original Ducati clutch model 748/916/996 Code: 041 PD 048

Basket: 003MG021 (anodized red)

Remembering, that price was about 490€ last year here basket with all plates...

These both fit to 907 and to my ST4S at least... But as i told, i dont know exact fit to 750 Paso, but remebering, that it have same basket also....

but 907 and St4 don`t have the circlip in the clutch basket as the P750 does. You`ll have to modify the clutch basket.

Yes, remembering now, whatkind it was in 750 and propably U are right... Anyway that my kit is for my ST4S, not for my 750 Paso, what i want to keep stock(clutch).

But maybe only that groove is missing... I check just, that STM basket dont have that groove...

Just ring VeeTwo near where you live or Phil at Road & Race on 02 43 884211. Phil will give you the right advice.

You didn't say how many Kilometres you have done, this makes a difference to the answers (unless I suppose you are into burnouts) I have 70,000km on my 906 and the clutch is fine at the moment, but I don't ride in heavy traffic a lot either.

Well, apparently the clutch is completely cactus! And only 77,000klms too! :toofar:
So it's off to the shop I go. I am getting a new clutch and a complete bottom up gasket replacement kit for the engine!!
There goes my superannuation!!!! I'll let you all know how much this little episode is - the bike has been there a week now..........just as well I love the bastard!!!

See ya in the wind,


Ian

On my old 906 I had to replace the clutch at only 30.000 km , even if I used to ride very much in the traffic.
Ciao

Well I finally got my 906 back on the 23rd with a new clutch and full gasket kit - AUD$1497.00 thank you very much. I suppose it's all the labour......
