ducati clutch issues.

[cockercas]

Plates on a 2005. My phones flat but as soon as I charged it up il do a plate check and tell you.

[Stu]

plate only donates when it was registered this is why they ask for chassis number

My TL was a 97 model registered in 98 so was on an R plate

plus it depends on when i ducati updated the bike too it could have been for august 2005 and his could have been registered before then

it can be a right pain in the arse when its crossover year!

[cockercas]

First registered on 30/08/2005

[Stu]

ask ducati for the build date from chassis number

did he get the clutch parts with the reg or chassis number?

although the clutch could still be the same

[Stu]

by the way I think you have the right clutch

searching the part number the same clutch fits 52 ducatis!!!

and your stack height is right too!!!

seems like we are going round in circles here!

[cockercas]

I got the bike tonight.

Checked stack hight and its ok. Google threw up 38mm and 36.5mm. Tride both. 36.5mm dosent get you out of nutral.

Re bled the system and no air come out.

Checked the plate bearing and thats free.

And the problem is still there.

[Grumpy Old Git]

Also did some digging as this issue has intrigued me!

The build up of the plates and the stack height is good. The plates are all flat (you checked).

The only things that leaves are:

1. The clutch is overheating with use and plates are warping causing the clutch to partially engage.

2. There is still air in the system which is allowing the pressure to 'creep' down. if possible tie the clutch lever fully in overnight (it may work). Even better if you can borrow a vibration plate and leave the bike back wheel sat on this overnight.

Otherwise I have no further ideas.

[cockercas]

Any ideas are good.

What would cause the clutch to heat up like that?

[Pete]

I read somewhere recently about bleeding the brakes on a BMW GS and sometimes air can get trapped in the master, so leaning the bike this way and that frees it up.

Long shot but could work?

[cockercas]

Im 100% sure theres no air in the system.

[Stu]

one thing that makes it overheat and expand is it not clearing properly and the plates dragging

this makes everything expand and warp and makes it worse until it cools down again

[Tango]

I take it that you're getting full movement on the slave?

[cockercas]

I assume so tango, how would I check?

Clutch works fine when it's just in and out.

It's just like it can't maintain pressure when the clutch is pulled in.

[Stu]

tie the lever back over night and in the morning with the clutch still pulled stick it in gear and see if you can push it

you may be losing pressure

the fluid could be bleeding back through the seals

[cockercas]

I've just text him that stu.

Il update again tomorrow.

Thanks to all that's commented so far.
