Decided to upgrade my clutch /pressure plate on my Series 3 V12 yesterday. Showed up at 9 at my friends shop this morning , and with several lifts available, got right to work.....stopped for a 45 minute lunch......had to fix a starter connection, but basically I was out the door around 3:30 in the afternoon. Please, please fellow Series 3 owners, there is no need to pull your engine for a clutch change !!! Feel free to drop me a line, and I will talk you through it. Please don't call me and tell me it can be done ....please !!

1973 OTS V-12.......since new.

Trick is to shorten driveshaft, about 4 inches, replace with appropriate length of telescopic section. Any driveshaft shop will do it for less then $100 US, including re-balancing. That's the trick. No pictures needed. With the extra room, procedure is same as removing / installing any standard transmission. Easy.

I think you mean not to tell you it 'can't be done John, but never mind. Nobody ever did tell you that AFAIK. What you describe is common practice with V12s, which have no reaction plate. This applies even more when there are helpers and a car lift available.

You got push-back on JL for initially refusing to give details like it was a V12 and also admitting it was a shorter non-standard gearbox with solid custom propshaft with sliding output yoke, where all E-Types already have a telescopic sliding section from the factory. Most of all, you got flack for insisting that this same process can be used on all models of all series (i.e. six cylinder E-types), which was not true then and still isn't true.

Other than that, I wonder why did you go to an undersized 9.5" clutch when it had (or should have had) a 10.5" fitted? I don't recall my various V12 flywheels being drilled for a smaller clutch, although many sixes are drilled for 10" coil and 9.5" diaphragm. 1 guess you went for a competition spec smaller clutch? Hope it works out, but possibly a more progressive and lighter pressure original 10.5" might be easier in New York traffic.

Doh - what a schmuck!

I -ahem - “speed read” it as 9 point 5, probably because I just received a competition 9.5” clutch and expensive ball release bearing for my 4.7 engine. Reminds me of that ‘Paris in the the spring’ optical illusion. That, and the schmuck thing.

Of course, I could be using schmuck in the German sense, not New York.

Talking of Germans, anyone heard from Carsten recently. I know he had a bit of a health hiccup a couple of years ago so I hope he’s OK?

Carsten is a brick!

And he's one of the few non-Brit's who would 'get' that.

Hi Steve: Sorry, but no pictures. Frankly, wondering what you want pictures of ? A couple of guys removing the gearbox, sliding on a new clutch and pressure plate, and shoving the box back in ???? Its much too simple to record with pictures. You don't photograph oil changes I hope. Not much more complicated if your using a shortened drive shaft. Take a look back at my posts. When you need a new clutch, you will find it's not such a bad job. All the best !

QUOTE: "Decided to upgrade my clutch /pressure plate on my Series 3 V12"

What was the upgrade vs stock?

I am contemplating this very thing now that I find I'm getting a bit of slippage when I floor it in 4th gear. I currently have a Fidanza flywheel and a stock AP pressure plate provided under the Jaguar part number C33176. I had to remove the TO bearing contact thingy from the pressure plate due to having a JT5 transmission which uses a hydraulic TO bearing. This arrangement has probably less than 3000 miles on it since installation though it did get some abuse recently during some tuning issues with the fuel injection which caused take off from a stop to incur quite a bit of clutch slippage just to get going without killing the engine.

I am considering some of the after market pressure plates that have a higher pressure rating and am having a tough time choosing the correct one. These are available mostly for either GM or Ford. I've heard that the SIII used a few parts from American manufacturers or at least their designs, for instance I believe the power steering pump is actually a GM unit.

My questions are, what standard, if any, did they use for the pressure plate? Does anyone know what the mounting bolt circle is? I've seen 11.625 and 11.675 for GM and 11.375 for Ford 10.5 inch pressure plates. Does anyone know what the static pressure rating is for the stock AP pressure plate? I've seen high performance pressure plates rated at 2400 to 3000 lbs. but would like to know what my starting point is with the AP pressure plate.

Are the specs of the stock pressure plate available anywhere?

If anyone has a pressure plate or flywheel for a V12 not in the car, could you take a measurement of the pressure plate mounting bolt circle?

I don't know how many times it is necessary to repeat this before the message gets through, but it is IMPOSSIBLE without butchering the floors and tunnel to remove the gearbox separately from the engine on an XK engined Short wheelbase E type i.e. any OTS or FHC 6 cylinder car . Will you please stop misleading people about this

You don't have to butcher the floor, in fact, floor is not touched. There is some trimming and minor altering of the tunnel , but not visible once instillation of gear box and work has been completed This in no way affects the structural integrity of the car. Not a easy as the long wheel base car, but is absolutely can, and has, been done.

Will you please stop misleading people about this.

Hi Steve, not an upgrade, just new. In the Series 3, the EXEDY clutch kit # 04021 does the trick. 10.5 inch, 10 tooth. Cheap, available from most suppliers. Its all you will need, and stay with old style heavy flywheel. Don't want to be reving the engine more then you have to in order to get moving. Have fun !

Not looking for credit from you or anybody else. Get a grip on your ego. I am here to learn, and possibly offer a few shreds of advice from my over 50 years of working on cars as a passion. If it helps someone, one person, mission accomplished ! Why are you here? Oh wait.....I know the answer to this........who cares.
