Hello - I just purchased a New Clutch Kit Assembly Super Set from the States. I think it is designed for a 1980-82 Turbo 924 but dont know much about it. It seems the clutch was just stuck and I really dont need the kit - anybody need one?

The 82 931 uses a different setup than the 80 and 81 931. You'll probably need to take photos of the kit so we can figure out which one you have. You should also specify what's included...is it just the disc? Or does it include the pressure plate? What about guide tube? Pilot bearing? Throw-out bearing?

I'm sure one of your fellow oz-landers will be interested...

Dan, on the subject of the 82' rubber centred clutch. Do we know when in 82' this change was made? I've always presumed it was late 82? Upon checking the logbook of my deceased 82' it has a UK registration date of July. The car also featured the modern front sway bar arrangement too.

I know this is probably trivial stuff but...

For the RoW cars it seems the cut over from spring to rubber damper was around June 1980. I had issues finding this out as every motor parts seller kept quoting for a rubber damped clutch. Here is the link to the Sachs product codes for the two products. The flywheels are different and the right clutch is needed for this. There is a caveat that there may be differences here for the US and Canadian cars

Attached is the data we have just discussed. On further digging (and I’m glad this has come to light now before sending you the parts) the Series 1 & 2 924 Turbo clutches are very different.
The attachments are taken from the ZF Trading online parts catalogue. ZF now own Sachs. This is the most up to date clutch information there is, and ZF will warrant this data.

The 3000 951 728 is the clutch kit you ordered from our site. Clearly with this new information, we will now supply you the following parts instead :-

3082 087 031 - Pressure plate
1861 684 132 - Clutch disc
3151 088 201 – Release bearing

The good news is that it is the same price as the kit you purchased

As I said, we have been advised that this will take 2-3 weeks from our suppliers but we will keep you informed.
We will be modifying our website shortly to show that the 3000 951 728 clutch kit is for the 924 Turbo series 2 only.

I will also apply a 5% discount to the clutch purchase price too seeing as you are a member of the Porsche 924 clubs.

Feel free to post the attachments to the forums. Other users may find the data useful.

Regards
Max

I wouldn't be comfortable basing the parts split on info from a reseller. They are notoriously ignorant of our cars. Not saying you observations are incorrect...but we've had cases in the past where resellers have insisted an application will work for the 931 (do a search for Fidanza for one example) and ended up being dead wrong.

In OZ, ALL S2 cars had the 'rubber' clutch..... so that is basically all 924Ts built after late 1980. These are of course RHD ROW. Now whether this applies to other RHD ROW.......?
This I can confirm.... If you have an S2 and running CIS you obviously need the 'ring' gear flywheel for the crank trigger sensor. To eliminate the rubber clutch, simply swap out the clutch for the early US S2 clutch (and pressure plate preferably). I also believe that the S1 clutch plate will fit in the S2 combination. Yep. Fits like a beauty...i guess it's essentially the same as the early US S2.
Early S2 RHD ROW, as best as I can ascertain, had all the mechanicals of the US late S2, and then some. The only real differences were in interior trim in the early S2 OZ cars, where an amalgam of S1 and S2 bits were used.

Understand your issues regarding resellers being incorrect but this info came from a reliable source who contacted Sachs. Heres the fact sheets which failed in the previous post from Sachs.


Series 1 - spring damped


Series 2 - rubber damped

Reviving an old thread but I've just looked at the clutch out of my UK '81 series 2 turbo and it has a spring clutch fitted ????? From what I've read it should be rubber mounted instead of spring but I've read that the clutch from a 944 S2 or 924 2.5 will fit and there are more options for updated units for those cars. Is this correct???? Also, what power can a standard sach kit handle in a turbo - aiming at 250bhp do I need a stage 1 or 2 kit?? Bearing in mind this is a street car so maintaining drivability is important.

Very odd. Tbh I've never stripped a s1 but I dont get why it would need to be different to the s2 - same torque tube, same power capability (almost). I guess it's due to the timing wheel flywheel on the s2 but seems odd Porsche went to the expense of having a new clutch commissioned that was different to the s1 - unless it was already in the parts bin from something else???

[Euro924S2]

ok, I've been out to the garage and I've found some part numbers from the clutch I removed from my S2:

Pressure plate: 3032855099 (or maybe ends 8

Friction plate: 1861684132

Oddly the friction plate matches the posted number from Sachs for the S1 plate ???

Even more oddly is the pressure plate which doesn't match any of the posted numbers and on google searching would appear to be from a '80 3.0L SC 911 ?????

any ideas??
