wow! you really timed the clutch swap down to the last minute mate....

The clues were there. It just wasn't "quite right" when driving, despite holding up to the odd private road test. First clues were on the runway in CZ, and I'm glad it didn't pop there! :eek:

Was there a lot of dust?

That's why i can't be bothered to follow anything up with JBS to be honest. I spent £600 on a clutch which kind of dealt with 350ish lb/ft for about 18 to 20 months.... Plus some 2nd gear launches here and there, and about 50,000 miles.... Just want to know exactly what I had. At least with the new one I saw it get assembled and fitted to my car. I know exactly what I have.

but ive had a OEM clutch thats been dealing with 290lb/ft for 4 years, 100k miles, several track days, lots of traffic light GPs and it didnt cost me anything...

iirc didnt someone warn you about this back when you bought it? :confused:

Right, well sorry Jase that i havent got back to you sooner, was having internet issues last night :(

Like i assumed, its a JBS COTASTRAPHY F*CK UP!

They have taken a stock clutch, and just replaced the lining, cover will be a standard one which will mean that it wont beable to work correctly with the uprated lining to the best of its ability.

An uprated cover has a higher clamp load for a reason, and thats to cope with higher power out puts and to prevent slip.The lining i cannot understand though, are they paddles? or is it a complete circle with one piece. which they has bits of lining cut out of it? It looks absolutly **** imho, and as for taking the surface off the DMF, the surface is thin anyways so they cant really take much off it.

As a guy above mentioned, if they have machined down the DMF and cover then they have to make up for that by making the lining thicker.

IMHO, and this is to everyone else aswell, STEER CLEAR OF THIS CLUTCH FROM JBS.

The clutch has started life as a genuine OE clutch from sachs, only difference now is they have sprayed that red **** over it and machined down a few bits and put some dodgy lining on it.

If the clutch had of failed though jase, and it went in a big way taking the box out, then id have sue'd the **** off JBS.

Did they do this when you was there sarah???

Surely they should inform the customer of what there intentions are shouldnt they? as they are paying £600 for a paint job, and some dodgy lining that probably cost £50 max to make and apply to the plate.

As for machining down the DMF, again, they arnt designed to have this done to them, and like i said in the post above, its a good job the DMF didnt explode and take the gearbox out.:thumbdwn:

Just shows you cant take all the traders word as gospel on here

You cant take anything that JBS says as Gospel....... they try to bull**** you left right and centre, and thats not just me, but several people i know who have spent £5k+ with them on there cars.......

They way you have to be if you go to JBS is dont listen to a word they say, and do your research before you go in so you can put that James guy in his place, as he speaks so much **** he belives its the truth....

It's definitely been rubbing on the rivets - mostly at the back where they've not been peened over enough. Doesn't look like much though hence the marks are not very pronounced. Damn right they shouldn't be loose! :eek:

So whats a SACHS good for? Is it not kevlar organic and good for 400lb? And how much would it cost?

Well for a start, a genuine sachs one is made properly IIRC, the uprated cover with the organic type late is good for about 340-350 lbft, and the paddle type is good for around 390lbft.

The funny thing is though, that the paddle plate is actually cheaper than the organic one

I cant confirm these are the right ratings, but ill double check after christmas.

Doesnt look like it matey, if the rivits were making contact with the cover or the DMF then they will have worn a groove into them, and the rivits will have been worn down.

Hi

When I worked there , I was told nothing of this :( and I do not know the ins and outs of it

I unbderstand a bit of engines and how they work , but I have to understand some of what is said

I do know that the company did have a few issues with the clutch , but then they stopped dealing with them

I do know that the Kevlar did come in seperate to them and then they manufactured the plate from that

The DMF was just made completely flat and as far as I am aware not alot was taken off , just skimmed

I am sorry but we are going back a while and I am getting on in life :(

But I do know that Devonmikeyboy did go on to the same clutch as Jason did not have any issues with his and Mike said his is good up to the limit of the torque

Sorry if that is of no use to you

Sarah

I know ColinD and Des have both had problems with clutches done by JBS... altho they were 5 speed box's

As Sarah says, it was a long time ago and water under the bridge for her, she was just the pretty smiley face behind the desk at JBS, so its not really fair to expect her to get involved in this thread.

tho now shes awesome shes become an immensely efficient wallet emptying machine. (still pretty and smiley too of course!!)

Been following this thread with interest - Jason did time it well - got some serious use on whatever clutch it was.

Sarah, now at Awesome, has been absolutely special in looking after us lot, I agree with the comment that she should not be involved in this discussion...

Oh and even more off-topic, the Helix organic clutch Sarah sold me is performing flawlessly.....

Doesnt look like it matey, if the rivits were making contact with the cover or the DMF then they will have worn a groove into them, and the rivits will have been worn down.

If you look at the back ends of the rivets you will see a few of them are shiny. If you look at the picture of the DMF you can see some faint circular marks (not grooves yet). If the rivets are loose, as Jason suggests, they wouldn't be doing much other than just rubbing gently, rather than wearing a groove. Once the friction material wore down enough to expose the rivet heads, yes I'd expect to see grooves. The plate does look a rather shoddy job!

Edit: pic attached with area highlighted - looks like a circular groove to me!

Edit 2: and it's not even, again suggesting the machining may not have created a flat surface.

Nah i know that sarah and im not holding you responsible at all :lol: You were there when i came up though in my ibiza when you had 2 irish lads over having stage 2 on there mk4 derv ibizas. I also had a clutch fitted at JBS except i know mine was the real deal I got it from work :lol:

Think mikes changed his clutch again now hasnt he though? as he was getting constant slip?

Hi Mate

Yes I know who you are I tend to remember customers and I remember you was a mate of Mike`s

I have not spoken to him for ages and hope he is well

I was there just after them for my clutch on the Ibiza

P.s it was ok(Well for the time I had the car anyway)

good to see it all coming out now. Yes, I am very glad this clutch was taken out my car when it was...

I'm sure my new clutch will not go down the same route any time soon. You live and learn in this modding lark, and I feel I've learnt enough now to have made the best decision on the above clutch's replacement.

Those rivets look like the ones that might have held the original friction lining in place to me.

if they have F&S on them then they are

if they have F&S on them then they are

:confused: Sorry, can you clarify on this?

On the rivits it will have a F and an S stamped into them, this stands for Fischel & Sachs.

I will check tonight. I don't remember them having any stamps

That would be a fairly criminal way of reconditioning a clutch - just strip off the old friction material and bond the new one round the old rivets. Classy!
