Clutch Issues Update - Knackered

Hi,

Further to my earlier thread about clutch issues and an open cover, I decided to strip out the plates for a look, and I think my clutch is knackered. The clutch plates are pretty ropey and rusty looking, and the friction plates have hardly anything left on them. Also, the basket is clearly notched, I'm presuming it should have a flat edge where the plate tabs contact, not a set of ridges.

So, I suppose I am in for a new basket and clutch, wouldn't mind just doing the plates myself, but think I will put it in to a garage for the basket.

Oh well.....

Actually, the notches look worse than they feel, how much is acceptable?

Oh, and how do I upload a picture, the size limits for an attachment are way too low I think?

Thanks

There's a guy on ebay selling baskets, looks a good price to me...

As for the plates Ferodo do a set of frictions FCD0175 same as a Honda VFR

Clutch holding tool is availaible at machine mart £10.99 https://www.machinemart.co.uk/p/lase...hub-drum-tool/

Go on do it, you know you want to really.

Then when you've uploaded it you need the link for forums, you can't post a pic directly on here.

The fingers of the clutch basket can be 'dressed' (i.e. filed flat) provided the grooves aren't too deep. I think the recommended service limit between the clutch plate tangs and the basket is 0.6mm so you'd need to see what the clearance would be with a new plate if you removed the grooves. If you'd be outside the 6mm even with new plates then it might be time to replace the basket as well or consider an upgrade.

I fitted a 48 tooth Sigma slipper clutch to my S2R 1000 - a much smoother take-up, slipper action and quieter than standard too.

I looked at a few second hand ones for sale, and the pics don't look that much worse than mine, so maybe it isn't too bad.

How do I get the link for the forum from the postimages site? Sorry, I'm not much of an online person really.

Thanks

Also, what are the little indents for on the steel plates, are they just to help hook them out?

I understood those cutouts were to help the plates disengage but your theory sounds just as plausible!

Have a look at this Avanti page about clutch basics, which you might find interesting. There's a picture of a very worn basket and yours looks quite fresh in comparison!

Meanwhile, this diagram is handy for reassembly:

Basket has seen better days imho, plates will likely be much worse so will sure need replacing but new plates will wear quicker in a worn basket so its probably false economy not to replace it.

I'd be a bit wary of those clutch holding tools that bolt to the crankcase as its not designed to withstand that kind of force and may break, and then it gets expensive. The ones with the long handles that rest on the floor are probably a better bet.

I don't think I'd be so kind.

It's Fooked - imho of course.

Nah! That could be re-dressed it’ll just let out the lovely rattle sound more like mine

Out of interest how many miles has it done?

If you replaced clutch parts at Ducati’s recommended service limit of 0.6mm you’d be changing something every few thousand miles.

The Laser 5340 - Ducati Clutch Hub & Drum Tool that machine mart sell is rubbish ,mine broke first time I tried to use it , went back to shop and they would not refund my money.

Well, checking with various sources it seems that it is not excessive wear for 10,000 miles. I'm going to check the clearance, and if it's not too bad just replace the friction plates. You can buy CNC Racing friction plates on their own for about £100, as opposed the the full clutch plate set that Ducati sell for about £250.

One dealer told me I was lucky to get to 10,000 miles without having to replace basket and plates, seems a bit excessive to me.

Also, the Ducati manual makes no mention of spring plates as in the Avanti diagram above.

I was advised that the dry clutch assembly on a road going machine normally needs replacing somewhere between 15k and 20k. It just depends? In the same way; as how long does a chain and sprocket drive train last?
From my experience this is good guidance.
