Just playing with the set up on an old hillclimb special. I have two sets of 300lb springs, one 8” and one 9”.

how much actual spring compression is there per given length of spring? 
the dampers have 127mm of available travel, so approx 42mm droop and 84mm compression.

I think the 8” will allow more set up variation than the 9” as there is more space to adjust with them, or am I the wrong way round and would the 8” bind up?

I bought a full kit for my BDR car a couple of years ago and I’m never going to use it! It’s a Reverie `Hockenheim/Daytona kit with collector, ducting and the nosecone side scoop. Includes every clip, fixing and hose.

Cost £1800…

£1000, post at cost or collect from Suffolk.

Everything but the cooler now sold. Thanks all.

Mocal oil cooler. £35

All near Sudbury in Suffolk or I can post at cost.

Front Top Suspension Joints for Caterham 7. (Pair) (jackwebbmotorsport.co.uk)

 

…Check the T’s & C ’s first….

Looking for an old watts linkage kit- not for a Seven, so anything will do. Just for experimenting on a special.

cheap as possible please….

Is yours a short, live axle chassis?

Caterham seemed pretty fixed on motor position, so adapted things around the gearbox to suit.

My BDR has a 35mm spacer to the type 9 box to get things lined up….I wish they had shoved the motor back instead- it is so tight to get in and out, I have to remove the bottom pulley to do this. 

Getting a proper Arch chassis refurb will only improve desirability of the car. They built the chassis , they are the people to refurb it.

Out of interest, with all these bits heading to Caterham and questionnaires , I take it that they have sent you all a £50 parts voucher as a thankyou for your input and patience?

Good show! 

I have always done mine with the engine out. Water pump is a definite motor out job. You may as well, then you can change the oil return hoses hidden behind the belt.

After reading these posts the majority are for the layshaft. Has my old dad used to say “let it develop” 

Thank you all, and I shall remember not to call a sl*^e cylinder a sl*•e cylinder anymore 🙈

Could you call it a “Subservient component in the hierarchy of the clutch management structure” ?

Good point .

If it was a cable- clutch K, I'd agree, but a Sigma has a near indestructible concentric slave. My vote is with the layshaft, especially with a T9.

Yeah, we got a bollocking for using Master and Slave on temporary traffic lights!

Surely the layshaft is more a “ digger digga digga”, the crb would be a “ whrrr whrrr whrr”….

Sounds like the clutch release bearing ( thrust bearing). Cheap as chips, motor out job though.

They all go sooner or later, try not to rest your foot on the pedal while driving. 

Sorted. Changed the sensor(£23, in stock down the road) all good now.

A bit off topic, but sonny-boy’s Fiesta tdci won’t start this morning. Turning over, glow light ok, but no fuel smell from the exhaust.  
It has sat for a week. I’ll get over there and  plug in to it later, but my first thought is crank sensor.

I’ll check the fuel feed as it could have dropped back to the tank, but a fair bit of churning didn’t work.

Any experience of these motors out there? I see the sensors are cheap and easy to replace which is handy if it is this.

What bushes would you do and why?  The Caterham metallastic bushes are virtually indestructible and are certainly not in need of replacement on a car of this age surely?

The A frame to chassis, radius arms and damper bottom bushes. If I were to strip it down, I’d do them as a matter of course; they would have to come out for powder coating and, even if just painting, new ones would give me a nice feeling of a job well done ( I know, soft in the head). 

Down that way, PGM. 

TBH that back end looks about normal for the mileage- it’s arduous under there! From what I see, nothing structural needs replacing, just stripping and painting/coating properly. Do the bushes and get it set up properly at the same time.

May I suggest you talk to one of the many specialists in Sevens? If you are down that way, I’d recommend PGM, or Ratrace. These “Blokes in sheds” are the true backbone of Caterham ownership, no flash showrooms or service departments, just pragmatic, good value advice and service….Just my thoughts.

BTW, is that HWM “Not charging Aston Martin rates” for Caterham owners?

£1500 to replace the lights!! Drop it round mine and I’ll do it for a grand….

Honestly, they are horrendous! Really poor coating/ paint. My grill is 15 years old and has no rust. Bad batch?

Hi Wayne, the de Dion was first sold in late ‘85 I think. Yours will have rear drums rather than the later discs?

Wow! That is some set of t’s&c’s! 
Don’t know them, but wouldn’t touch them with a barge pole given those terms.
