HAVE A 1984 PORSCHE 928 S
I want to change the CLUTCH
My question is,
To access it, do I have to remove the headers?
Is it necessary to remove the engine?
or is there some other way.
Someone who can help me?

No. It would be a good idea to review the instructions for removal, inspection, and re-installation of the parts.

I may have some documentation on DYI removal procedures that would be helpful since the manual is not terribly thurough. I'll follow up later.

You're in luck. Not too bad to drop the clutch pack out at all. You'll need to remove the clutch slave from the lower bell housing, the Y-pipe, and then the lower bell housing itself.

You'll possibly need to place a rathet strap from one of the rear tires onto the release arm in order to fit shims into the 3 adjusters on the pressure plate. You need to be able to fit 3mm shims.

After these steps, you'll want to loosen the driveshaft couplers. Loosen or remove both front & rear coupler pinch bolts. Push the coupler as far back as you can. Be patient. The couplers break somewhat easily if you get too rough with them. Use some penetrating oil on the splines & move it in both directions until you can slide it far enough rearward to visually isolate the intermediate shaft from main shaft.

At this point, I loosen the 4 bell housing bolts until they're sitting in there by 2-3 threads. Now, go to the rear of the car and remove the 2 bolts at the rear cross member transmission mounts. Carefully pry the bell housing back from the engine.

Go back under the car & remove the 6 bolts that affix the clutch pack to the flywheel. Index everything for removal with a grease pen, nail polish, etc. Place a jack under the clutch pack once you pop the release arm off from the front ball cup... just in case. Now, remove the guide tube bolts & then you can usually push the release arm forward to pop it off the front ball cup from underneath. Otherwise, you'll have to go above to push it free from the mount at the rear of the engine.

Be very careful as you pull the intermediate shaft rearward to free it from the pilot bearing. The intermediate shaft will be all that is left supporting the clutch pack to the flywheel. Try to keep the intermediate shaft in place until you've indexed everything.

Gracias, el problema es que el manual de fábrica solo incluye el 928 y NO el 928 "S".
En el 928 "S" los cabezales bloquean el acceso al embrague.

Thanks.
The problem is the factory manual only includes the 928 version
The 928 "S" headers block access to the clutch

I have two 928 S, one 84 and one 86 and no header blocks the service cover under the car.

Be careful. I remember having to hold that heavy clutch package with the teeth digging in me and no arm strength to raise it.

If someone has installed the long tube MSDS stylw headers, they'll block the lower bell housing from being able to be removed. My 81 Euro S had those on it.

OP please post a picture so we can see what your working with

Hello Thank you all.
This is my Porsche 928, and these are the Headers it comes with.
Fortunately we were able to move one and we are accessing the clutch.
My question is, I am not the first owner, and I don't know if these Headers are original from the factory or were added later. It does not appear in CARFAX.

Kiln_Red

OP, you're right.. You're going to have to remove them. Those are most definitely not original.

Such things would not be on a Carfax unless the previous owner made a point to add it or the shop that did the work reports everything to Carfax. Shops that install such items would be stupid to be tied to Carfax in the first place.

Carfax is grossly unreliable either way. I've purchased cars with salvage titles at the insurance auctions that had a clear carfax.

I dunno, he already got the bellhousing off which is typically the worst part with headers. I'm able to pull the clutch from my 79 with the headers still installed, disconnected from the rest of the exhaust and the right side (passenger) one loose from the head.

I do have to "persuade" the other header over a bit when dropping the clutch.

Oh come on now, it's a rite of passage to drop it on your head at least once, or was that just me?

What's the general consensus regarding the Dual Clutch in the 928?
