New pressure plate
 

I've just bought a nice new anodised pressure plate. The seller said that it would fit a 748 to 998. I've just tried fitting it to my 916 and the screws seem to tighten down too far squashing the springs down! When removing the plate a toothed spacer fell out and I refitted the unit without the spacer. All seemed good but gear change is a problem, am I going to be able to fit this plate or do I get my money back?

Was the "toothed spacer" the last of the driven clutch plates?? If so, it has to be in place.
That'd cause the springs to tighten down too far and get coil bound and also allow the exposed friction plate to eat the new pressure plate away.
Pull the plate off and fit the toothed spacer, then refit. If the spacer is the driven plate then all should be fine.

Clutch
 

Which part are you on about? See attachment.

Have you got the mark on the clutch plate lined up with the post with the horizontal mark? When I replaced my clutch plate I found that I could not release the clutch with the clutch lever. By slackening off the clutch springs and applying the clutch lever I found that the plate would move and then I was able to tighten up all the cluch springs. They look like then are fully compressed when tightened but that is how they function.

Thanks guys!

I'll go and have another go!!!

FIXED!!!!
The plate didn't have the mark to line up the with slotted pin!

Thanks for your help!:burn:

Still having problems!!!
All seemed good but the clutch was a bit stiff, on closer inspection I noticed that the springs are still compressed more than when the original plate was on. The new plate is thicker which means that when the 6 bolts are tightened the plate movement is reduced. I've put the original plate back on and all is good! Any ideas????

If the pressure plate is thicker then you may need to reduce the thickness of the clutch plate stack. This would mean changing one or two of the thicker drive plates for thinner ones to gain the correct clearance.

Cool!
I thought I was going a bit nuts!:puzzled:

Is this normal when adding an after market plate?
Is it worth doing or do I ask for my money back as the plate doesn't fit?
And now I've notice that I'm losing clutch pressure while in traffic, I think I've done some damage to the O rings or pipes!

took my plate off and the rod which goes thru the clutch came too, couldnt see any way of removing it?? Does it just 'pull' out?

Hi,

Yes the rod does just pull thru, but a light tap with a mallet separates them! I've just spoken to someone at Pro twins and he said I may have popped the slave cylinder seal. He has suggested fitting a Ducati Performance clutch plate instead of the un-named version I have.

Was thinking the same thing - loss of pressure you're experiencing sounds exactly like when my slave cylinder seal went.

I got a TecMoto one, with a better ratio - never had a problem since...

Cool!

Annoying thing is that it a new Ducati slave cylinder! Pro twins have suggested just replacing the seal with one of theirs!

What is it with the Muppets?

the clubs full of them.

they'll have to start coming up with new characters prior to next years trackdays.!

I'm keeping mine as it's been my nickname for years!
Very worrying!

Animal, Just had one of the new SMS 48 tooth clutch kits fitted to my 996 with the new SMS Pressure plate, a work of art and so much quieter. More than likely last longer than I will:lol: Four times the life of a standard Ducati one . Ill test it out over the week end . Expensive but what aint nowadays when it comes to bikes . On the issue of the slave cylinder,Cornerspeed do a very good replacement with three seals not just one as in the standard Ducati type,excelent bit of kit. Regards4D

Hi,

I've already check them out on the cornerspeed site, it seemed alright on my ride home tonight. I'll do some more testing tomorrow!
