Why everyone would ever need a clutch is way beyond my comprehension but that is another subject 8>.

Lots of peeps calling in a panic about clutch parts going NLA - so just wanted to add some positive news.
Double disc clutch plates 78 to 86 are readily available as are the pressure plates but in smaller quantities. The TO bearing became NLA a while ago but Classic brought it back again.
Intermediate plates - ------
Clutch Pressure Plate Intermediate 77 to 79 928 116 033 03
Clutch Pressure Plate Intermediate 80 to 83 928 116 033 22
Clutch Pressure Plate Intermediate 84 to 86 928 116 033 26
03 & 22 from Porsche and Sachs have been NLA since 2014.
26 was available up until recently but currently out of stock at Porsche. The good news is the part is being up-issued to another number which means it will continue in production. Availability is not defined at yet but probably within the next 6 months or so.

Single disc clutch 87 to 95.
TO Bearing readily available
Clutch Plate readily available
Pressure Plate ---
Clutch Pressure Plate 87 to 88 928 116 004 10 - Germany has 12
Clutch Pressure Plate 89 to 91 - was 928 116 004 12 SS to 928 116 004 16
Clutch Pressure Plate 89 to 95 928 116 004 16 - Currently not available but still a current production part - check with 928 Intl has they probably have stock.

I did a GTS clutch, last month, that needed both a flywheel and a pressure plate (tremendous amount of "hot spots".)

Getting pieces was.....incredibly difficult.

Porsche only offers the flywheel on a "rebuilt basis", with a large core charge. (I have no idea how they plan on "rebuilding" a flywheel with "hot spots"....they are junk.) The "rebuilt" flywheels are brand new pieces, in the "rebuilt" box. They shipped me three flywheels until I got a "rebuilt" (new) flywheel that was not made improperly. (Not handy, when it comes from Germany.)

Porsche had no pressure plates. 928 International had no GTS pressure plates left, but they had what was marked as an '89-'91 pressure plate (which turned out to be a GTS pressure plate in the "early" box.)

I had the car three weeks, torn apart on a lift, for a clutch replacement.

There's a reason I've been working on a lighter, smoother, easier to get pieces for, alternative.

Thanks GB - I think it was your recent post that started the panic buying spree.

2 of those in stock as well as a disc

I'm certainly smart enough to have ample pieces on my shelf, now. Having a car apart on a lift for 3 weeks, for a clutch replacement, makes it tough to make a living, in my world.

I saw the "writing on the wall" and as soon as the double disc clutch was done (which was what I had a need for, I started work on the single disc version.

And as far as Porsche is concerned:
They might have GTS pressure plates on order....but it took 8 years to get a new early T/O bearing built, right?

Timely thread as I’m staring at this and deciding what to do.

What was upgephuked with the first two?

GregBBRD

Big really rough gouges in the flywheels.
There was apparently:
1. A major earthquake as they were machined.
2. The CNC lathe had a power failure to the computer, but kept machining.anyway.
3. The machinist went to lunch during the process.

I know Roger very well. I’ve been buying parts as an individual, from 928 International as well as part of a shop since 1997, have two orders this week with him. I have several parts from Greg on my Ultimate 928 build. I respect all 3 of them immensely. To the N’th degree. 928 owners fall into many categories. Stock restorations and must at all costs be stock factory (not Oem) parts. 928 owners who enjoy the car and do what they can to keep their 928 on the road. Guys that mod the crap out of their 928’s and need better than what Porsche designed in the late 70’s and revised over the year.

I say as a community, we support our vendors for their strength, and their positive impact on the 928 community.

In addition to factory parts from Porsche... I have parts from.... wait for it...

Roger
928 International
Dave Roberts (aka 928 Specialtists
Hans
Devek (dead to me)
Lindsay racing
Crane Cams
928 Motorsports

can’t we all get along?

The Forgotten On

Pretty sure Devek is dead to everyone

But yeah, I'll buy parts from anyone and everyone depending on what they in particular are selling.

I'll buy OEM and used generally from 928 Int. because they are close to me and have great prices

alternatives from Roger because he offers so many

I've bought parts from 928 Specialists for AC work

random performance pieces from 928 Motorsports

And of course Greg's beautiful better than factory parts like his alt, harnesses, and internal engine parts.

Myself and I'm sure many others share your sentiment of trying to support our support network of 928 suppliers. Without them I'm sure even Porsche wouldn't support the cars like they do today.

K. So all evidence very subtle. NOT.

Yall are forgetting the Greg Brown fuel hoses that are a must have for the later cars.

You guys might be taking this wrong....Roger and I are not being combative....I'm certain he will sell my new clutch.
He's just making the point that stock pieces still exist....somewhat.

Right now. You're in great shape redoing a stock clutch, as long as you own an early S4....and no more than 10 of those thousands of cars need a pressure plate. If you've got an '89-'95 car....sorry no pressure plate. And those cars, because Porche provided no cooling to the bell housing, virtually all have very "cooked" flywheels and pressure plates. Virtually every car needs the pressure plate replaced!

If you own a '78 to '86 car and need an intermediate plate.....sorry.

I'm not trying to eliminate stock clutch pieces...I've got thousands and thousants of dollars of that inventory....

I'm try to "future proof" our cars, by providing a "better than original", "smoother than original" , "releases better than original", simple alternative to the stock pieces....which are on the very cusp of not existing.

Keep in mind that my business depends on 928's running...and moving around. If clutches become a supply issue....manual transmission cars become cool "hanger queens".

I just made a fantastic alternative solution.....

Great job on that Greg. Anticipate using them at my shop in the future. Well done.
