Clutch ford kent 1981
Discussion
Hi folks,
I bought a caterham 7 super sprint for 1988 in January from the UK. The car is to me impossible to drive on road because it has a sport clutch from AP Racing and I wanted to change it over something more easy to use but I have a lot of difficulties to find the right parts. I have been searching for weeks now but can't find anything so I was hoping someone could help me:
Engine:
- Kent x/flow 1650CC
- 7E9 I AX
- 831C 6015 R34
Engine was bored out to ? and last dyno report from1995 says 175bhp at 6000rpm (at flywheel)
- Flywheel: 70HM 6384 BA
Current clutch:
- Plate: AP Racing CP3219-1 (23 splines)
- Clutch cover: 71BB7505AC // TF5835 – PII – 04 // 190337
Gearbox:
- Ford 4 gears
Please help me find a new clutch plate, or full kit that can be mounted on the current flywheel and with current gearbox considering the power of the engine and of course at a reasonable price :-)
Thanks,
Raffaele

Hi Lotobear,
thanks for your reply. What I see is that all clutche plates from your link are 190mm but actually the one that is currently installed is a 184mm and when I take some measurement on the flywheel, I'm afraid the 190mm won't fit...
I was thinking maybe I'll have to change the flywheel as well but I don't know which model will fit the engine

The flywheel part number comes up as a pinto flywheel, but that too has a 190mm clutch.thanks for your reply.

Regarding fitting for a new flywheel, presumably you can use one of the standard Burton ones getting things like the ring-gear correct?

Hi BertBert,
thank you for your reply. I'm far from an expert in mechanic and in fact this is my 1st time I take an engine our of a car and that I am looking at a clutch and flywheel
Because of that, I don't know how I can find a flywheel and be 100% sure it sill mount on the engine.
I was wondering maybe that's me who's miss-interpreting datasheets from clutch plate. When we say 190mm that a is the diameter of the disk plate right? Because in that case I'm sure that clutch won't fit the flywheel.
I have attached a picture from my flywheel and the clutch, hope that help you to help me to identify it and find replacement one

Ah, that looks like a very lightweight flywheel designed to use the smaller clutch. I think you need someone more expert than me.
Perhaps the Burton lightweight flywheel is the right answer with new clutch.
Are you able to call Burton power? If they are manning the phones they are quite helpful.
I presume you are outside the uk. If it would be helpful, I'd be happy to phone them for you and see what they have to say.
Just let me know.
Cheers
Bert

It may be the case that the super light flywheel is more the cause of the 'difficulty' in use rather than the clutch per se?
Have you considered using a more standard (heavier) flywheel and clutch asembly from, say, the Lotus Twin Cam? Unless you are thrashing it everday on the track you might find it more than adequate and certainly more 'friendly' in use. I've used a standard TC clutch in a much heavier car than a Caterham (an Elan +2) with a 145bhp TC and it was more than up to the job.
Are you using the Ford 3 rail 4 speed 'bullet' type box?

Thanks to both of you for you support. Very much appreciated!
I did had a 1st email exchange with a sell person from Burton (Mark Calder) and he was also proposing a 190mm clutch. Then I sent same pictures as I posted here but did not get any rely since then... So Bert, yes indeed I am French living in Belgium (betrayed by my english I guess ). if you are ok to call them for me that would be FANTASTIC!
At this point I would not mind changing the flywheel as well to something more 'conventional' as long as I don't go to something unaffordable (I was thinking max 600 / 700GBP for the whole set). Indeed I am not planning to race with the car but to use it on the road so I need something more soft to use.
Regarding the gear box, I'm not sure how I can check that (Ford 3 rail 4 speed 'bullet' type box). Yes it is a Ford 4 speed gearbox but I don't know what the '3 rail' and 'bullet' type is
Cheers,
Raffaele

Your Ford 3 rail will look like this. 'Bullet' actually refers to the version of this gearbox with the 2.51 first gear ('tall' ratio) which then allows close ratios for 2nd and 3rd.
The reason for asking was that the number of splines on the input shaft would suit the Lotus TC clutch.
...you probably know already however the Lotus TC is essentially a Kent engine with a twin cam head.

When ordering a clutch. Are you sure you are taking the correct measurement.
I'm guessing that your supposed to measure the fitment ( across the hole centres ). Not the clutch plate itself.
From your picture that would make it 190.
Ask Burtons where to measure to confirm.
Hope that helps.

He’s just said it’s 200mm across the mounting holes. I'm guessing that your supposed to measure the fitment ( across the hole centres ). Not the clutch plate itself.

I think this is what you have got...(I know it says pinto, but the part number in your spec is a pinto clutch).

So it's a 184mm racing clutch. You've not said why it's not suitable for road use, but I suspect it's a combination of the lightweight flywheel and the clutch. Can you post a picture of the clutch plate?
The standard flywheel I think is this...
https://www.burtonpower.com/steel-flywheel-ring-ge... £264
With a clutch...
https://www.burtonpower.com/luk-std-clutch-kit-for... £79.90
Now that's just me looking at the Burton website and I didn't have time to ring Burton today. I can do that Monday.

Hi Bert (or Graham I'm not sure )
thanks a lot for your research! I did spend quite some time on Burton' site and others but did not found this flywheel. So I understand it seems that the flywheel that is currently mounted is a lightweight racing flywheel.
Indeed the problem is not really the flywheel itself but the clutch. The one I have is also racing clutch plate and therefore without springs. I wanted to change it but it's 184mm and I can't find any replacement clutch of this size with springs and that can handle the 175BHP of this engine. That the reason why I was considering changing also the flywheel but did not know how to find suitable reference/model.
Here is a picture of the current AP Racing plate
The flywheel from Burton that you are showing looks very much like mine except the number of wholes in the center is different from what I have. But we are getting closer

Ah whoops, gave away my identity secret there 
Don't worry about the number of bolt holes, I think that's just to allow it to fit 4 and 6 bolt cranks.
That certainly looks like a fierce clutch. With googling, I can't find a clutch of that size which is not a race clutch. So I suspect you'll need a flywheel and clutch. I'll be talking to my race mate over the weekend who does this for a living and will see what he thinks.
Happy to call Burton for you on Monday now as we definitely know the questions to ask.
Cheers

The solution is a change of flywheel and clutch, he's sending me a parts list. You can only get race clutches for your current flywheel. And that flywheel is never going to be happy on the road.
It may be easier to discuss by email rather than on here and I can forward the parts list. If you use the mail thing on here to message me with your email address, I'll forward the list when I get it. There will be a few things to confirm as well.
