Clutch Replacement

[Needle99]

Hi All,

My clutch badly needs a new basket and plates...

Below are pics of my hub....

Would you replace it at the same time based on the few wear marks on it? As far as you can tell from pics in the basket still.

cheers

 I have never replaced a Ducati clutch, but if it were mine I would replace the whole works. When one component of an assembly is not replaced it accelerates the wear on the new parts.

Depends on how much money you got.

If you dont have the funds, you can get away with double stacking one of the metal disc. Doing so will offset the metal disc by 1 plate, it will extend the life of the drum. and it will also extend the life of the basket.

I think i sold all my spare clutch parts to koko64, but if ive got a few parts left, ill hit you up. Ill let it go for pretty cheap. I dont run dry clutches anymore ( on a wetclutch 1100 now)

From what I can see, replace the basket.

Can't see the plates.... Did you measure them?

Hub looks fine.

How many miles on the clutch/bike?

[Needle99]

Hi guys,

Thanks for the info so far :-)

He Man - I guess koko bought the Nichols basket from you?

Speedog - 2004 S4R has original clutch and has done 25000km. Clutch friction point is right out at limits.
Have not measured stack height yet (have ordered a Dig Vernier caliper) but the playes are pretty rough. Plan on cleaning them up and can keep as additionals for when the new stack wears.

Pics of plates below, but they are done as far as I can tell (not that I know anything). Don't have a good pic here of actual material either...

Plates usually last longer than that, but... not always, depends on how and where the bike is ridden.

Stack height will tell a good bit.
Usually the innermost steel is dished, provides a slightly wider engagement range.
Watch for that effecting the stack height measurement.

What was the clutch doing/not doing?

[Needle99]

Issue was mostly the narrow engagement range. When hot the likelihood of stalling was quite high..
Also very noisy (relative to my brothers M1100 with half the km's)
Not sure if normal (new to Ducati and open clutches where you hear more) but while riding along it could take a fair while (15 seconds) before you would hear/feel a click and the last part of engagement would occur.
I think there was also a fairly big slip when pulling out on a hill on the weekend, so just feels like time....

Now to decide which to get shipped here to Aus...
EVR 48T Basket/Plates set
or
Desmotimes Procutting basket and Barnett Clutch plate pack

I like the 48T baskets. but, those clutch packs get expensive. my 30k 1000DS motor has eaten 3 stock packs. but i also ride in the city a ton. the upside is i always find people elling their relatively new ones for $50-$100 depending on condition. retial price on a pack is $250+.
The clutch packs teeth doesnt look that bad at all. I would run your basket for a few thousand more miles without looking at it. you should see how bad one of mine are.

I dont think you should be stalling with a worn clutch pack. You have the exact opposite effect. Since the engine and teh wheel cant engage, if you whomped it, youll get bad acceleration because theres no resistance from the wheel (or engagement at the clutch). You should check if you have air in your line instead.

I've installed the procuttings/barnett combo on my s2r1000 and highly recommend it.
I will go this way every time i need to do clutch work. (very quiet)

[koko64]

He Man's correct. Could be air in the line and crusty fluid, or failing slave cylinder. Check your pressure plate bearing while you are in there. The basket is chopped, but strangely the plate tangs look ok in the pic. Measure the  plates individually and the stack for wear as has been mentioned. I havent tried a Procutting basket (sound excellent) but the Nichols baskets are very good. I am using a used Nichols and its tolerances are better compared to some new baskets when I measured them. The EVR kit and Nichols are sold by our sponsors. I had a thread on the tolerances and weights if you want to search for them.

[Needle99]

Thanks Guys...
Slave is a 14 month old Ducabike part (new fluid then)... Has been bled a couple of times, but doing again will not hurt....
Will check the bearing as well, assume was a new one with the DP pressure plate previous owner put on...
Koko had read your post re tolerances. The Procutting sounds similar to a Nichols in tolerances...

Sponsors having the EVR 48T basket/plate combo is one of the reasons for looking at it (also 25% cheaper inc freight to Aus) 
Plates are not as bad as I first thought when I look again now (taking pics)...




Stack height is roughly correct (new measuring implement will arrive Friday (hopefully)


Stalling could just be new bike syndrome (new to me anyway). Clutch is very diff to my SV650S previous bike....

[Southpaw]

Yeah, the SV650S clutch is a much different feeling than the Monster clutch(I also came from one).  The SV I found had a giant contact range for the clutch, whereas the monster is much smaller contact(a much more sporty feel on hte clutch)

FWIW, the biggest performance improvement I have felt in the seat of my pants was an aluminimum basket and barnet clutch pack. I have done a TON of performance mods to my M1100 and for some reason the lighter clutch combo made the biggest difference...
