Symptons of worn clutch basket

[flanagaj]

Can anyone tell me what the symptons of a worn clutch basket are ?

Thanks

[Glyn]

noise
yep more than normal
only quivk job to pop off the pressure plate and have a look

[Jools]

and you might find the clutch take up is a bit clunky as the plates ride over the grooves they've worn in the basket...but as yer man says, tis only a few bolts to take the covers off and have a gander

If there are any grooves does it mean it needs replacing ?

[Fordie]

Oh yes, there will be grooves,depending on whether the clutch plates have embedded grooves into the basket or both.On inspection you will see both the plates and basket and see how much wear has taken place. Plates dont last forever unless your'e a polishing merchant,one that does'nt get out and ride it, any thing from 12,000 16,000 mile depending how much stick you give it. 4D

Is it a job that is easy to do yourself ?

wont as long if its a slipper clutch

[Fordie]

easy peasy, cover plate of, undo the spring/cup bolts(allen key) that will free the pressure plate,the clutch push rod may want to come out with it, thats about 12" long in old money.It should really be free,it sits in a bearing in the pressure plate. take out a few plates to see the WAT (wear and tear) assess and replace. 1/2 hour job . 4D

about assessing the job

[andyb]

who Fordie...............

If you need/want to change the drum you need a big socket, torque wrench and a clutch holding tool.

[Fordie]

Better still AndyB, you need NELLY Actually changing the basket is a little more involved and special tools are reguired,as you say not a DIY job really. 4D

[Glyn]

its not hard pete
i managed it
as andy says you do need a cluth holding tool also a bloody big torqe wrench
to just assess the condition though is as you say a very easy job

Its not actually that big a job, even with a slipper. your right though if in doubt get it done by someone that knows........and has the kit!

[Glyn]

i nearly popped a testie trying to do that damn nut up:o

[rockhopper]

The service limit on the basket is a lot less than the amount of wear that actually starts to cause a problem if that makes sense!!

In other words you are supposed to change it but in reallity it will keep on working for ages.

Symptoms are jerky clucth release as the plates slide over the notches in the basket fingers. You can dress them out with a file though. This will result in more noise unless you are running ST4S alloy clutch plates.

i could of leant you the tool.tool.... You in tomorrow?

[flanagaj]

Looks as though the plates and basket have worn. In the Haynes Manual it says that if the engine is in the frame you can just put it in gear, press the back brake on hard and remove the clutch without any special tools.

Is this correct ?

PS - Should I go standard basket and plates or buy a slipper ?

Either way can anyone drop me details as to where the best place to buy is ?

Thanks

[rockhopper]

Really depends on how good your back brake is and if you have someone to help you. I think the big nut is something like 180N/m. Some people put bits of wood through the back wheel. If you've got an old set of plates, some half inch bar and a welder you can make a clutch holding tool.

You don't need a slipper for road use. And they need careful setting up for the individual rider. If you mostly ride on the track, that may be a different matter. But, y'know, those DD guys manage with a stock clutch... :burn:

I've got an STM 48 tooth basket (conventional clutch, not a slipper). I got it from Nelly at Cornerspeed. It's a better engineered job than the stock clutch, but you need STM plates to go with it, and it's more expensive. I bought the set of plates and basket (you use your stock hub) for about 250 quid IIRC, but the basket separately is about 170 quid. It's a nice anodised aluminum job, and lasts longer than the stock clutch parts, so that offsets some of the initial expense. I was chatting to guy yesterday who races a very quick 996, who's got an STM slipper (same basket as mine). He said he used to get through three stock baskets per season, but his STM basket is lasting him into his second season

Thanks !!! I will check out Corner Speed.

It looks like a job that if you take your time and read the manual you can do yourself. Agreed ?

[moto748]

If you have the holding tool and a big breaker bar, yes. But on the other hand, it isn't a lot of labour for a professional with all the kit. I watched louigimoto fit a new basket on mine in half an hour or so yesterday.

And if you fit an STM basket, you can't use the "usual" holding tool, which locates in the 12 tooth grooves, so may need two holding tools...?
