S4s clutch release bearing

Recommended Posts

The S4 friction plate is definitely different to the S4s /300 one, (S4 has 4 springs s/300 has 6) so a totally different setup.

Which friction plate do you have?0

Not sure about the clutch, but I reckon the S4s release bearing comes up longer. Depending on the difference in lengths, you may well be able to ge the 9-12mm you need on the fork adjustment, because the hydraulic cylinders are the same for both models.

Yeah I’m sure any would work to be fair - there’s plenty of adjustment in the clucth hydraulic setup. That said - I do t want to be buggering about and reengineering the wheel

I would suggest that your S4s friction plate is slightly thicker than the S4 one, and the sleeve that sits inside the standard S4s bearing will be slightly longer than the machined extended inner race of the S4 one. So you're going to need to source the correct bearing and sleeve for your friction plate.

Have you checked the flywheel and cover are S4s or S4?

The covers aren’t interchangeable as they have lugs in different places

My S4s driven plate had 8 springs, the new S4 version has 4.

 

The flywheel I have is drilled for S4 or S4s pressure plates, as you say the S4 pressure plate won't fit otherwise. Unless you use an S4 flywheel, of course!

Yes I know, that's why I axed.....what I was trying to say was.....you have an S4 release bearing, you have an S4s friction plate, do you know which clutch cover and flywheel you have?

Reason is, I know how difficult it is when you buy a car as a box of bits, if you've taken the thing apart yourself you know what's what. If a PO or garage has replaced parts with cheaper versions to penny pinch (and I know you know what I'm saying), it causes problems like the one you have now.

Exactly, you're going to have to bite the bullet Barry and buy the correct parts, whether that be S4s or S4

Barry - please post photos of your clutch pressure plate (with any details or part numbers on it) and your flywheel face, then maybe we can finally put this one to bed.

Bollox, I was hoping there would be a number on it!

With the spacing on the bolts looking closer together than my S4 pressure plate (counting the flywheel teeth in relation to the holes), I'm fairly sure that's an S4s pressure plate you have. If you really want confirmation, then I have a spare S4s flywheel in the garage, and I could measure the hole centres from that.

It’s defo an S4s -  sj supplied helix clutch kit for what that’s worth

In that case, and if I were you, I’d use the S4s release bearing.

I know you can get a gearbox out and back in quicker than it’s takes me to think about opening the garage door, but......

from memory my S4s flywheel didn't look like that......has that flywheel been lightened? I don't remember my flywheel having a radius step on it like yours.....I have heard because of the big difference in price...people swapping out the S4s flywheel and clutch assembly for the earlier SE and S4 assemblies.

Posted by you on July 1, 2017-

the S4s 's flywheel is also stepped by about 1-2mm this is why you have to be careful if your going to get the face of the flywheel machined....and thats why the bolt pattern is different.....there's no reason why the friction plate and pressure plate can't be refurbed.....

 

Been on the whiskey?

Which one are you fitting? If it's the S4s bearing, you should be able to get one faster than that.

So far no-one either has one or is getting back too me. Somewhat fed up with it

Heres a rough sketch of the insert required, the shim size and the bearing
