Ok i've read this article http://www.our-nest.co.uk/Caterham/html_files/2002...
and am considering doing the swop (considering being the operative word).
Unless I've missed it I cant see which type of axle to use The english or the Atlas
I know the english is from the Escort and the Atlas is from the Capri. Also that the Atlas is stronger. But which one will fit width wise, or are they the same width. The Atlas i believe is 52" wide but what points are these measurement taken at. Upto the inside of the brake drums on the ital axle the measurement is roughly 50"
Would there be much alteration to do on the atlas etc.
Finally, are these axles difficult and expensive to renovate.
Cheers
Tom

Thanks for that. It say's in Phils home page about the small modification to the tunnel.
Do you know anything about the Koln axle. This is what I've just read and wondered if the Koln type has a diff similar to the Capri (ie larger) or will one of these fit?

THE AXLE IS A KOLN TYPE WHICH IS LIKE THE TYPE FITTED TO GERMAN SWEEDISH AND AUSTRALIAN CARS.

THIS AXLE IS A DIRECT REPLACEMENT FOR THE ENGLISH TYPE SO YOU WILL NOT HAVE A PROBLEM WHEN COMING TO FIT IT IN YOUR CAR.

THE WAY TO TELL THESE AXLES APART IS THE ENGLISH TYPE AS FITED TO ALL UK VEHICLES HAS THE DIFF MOUNTED IN A SEPERATE CARRIER AND IS FITTED IN FROM THE FRONT, THE KOLN IS LIKE THE ATLAS AXLES AND HAS THE DIFF MOUNTED DIRECTLY INTO THE AXLE CARRIER FROM THE BACK.

Hi Chris
I was led to believe that the ital axle wasn't upto much BHP (although 200 would be sufficient for me).
When you talk of a well built ital axle, what would that entail (I'm not too familiar with them)?
I don't have a problem with doing the work on an english axle, ie brackets etc as my mate has an engineering workshop and quite often makes custom build items for kit cars, such as the rear frame for a bike engined mini.
In fact we were discussing this afternoon the idea of doing an IRS conversion and recon we could do it for under £1500.
However then you get into the realms of which is best, Live axle, IRS, or de dion, and of course that all depends upon the main application you want the car for - track, road, sprint, drag etc
Cheers
Tom

Cheers Chris,
interesting stuff and certainly looks like a cheaper and less work option.

Out of interest, if I did go the route of an axle swop, what could I expect to get back for an ital axle with only 5000 road miles on it?

Chris,
correct me if i've understood wrong, when you say:
"Therefore all the impact, tangential load when you kerb jump is providing a massive bending force to the end of the half shaft, something it was never designed to take (the english axle is a design that is just as bad if not worst)."
So even if you shim up and replace the CW&P for a LSD, the weak point on either axle are the ends of the half-shafts. So it seams pointless doing an axle swop from ital to escort, you might just as well do the shim and CW&P and save yourself the trouble of the swop?
With the above in mind and Kerb jumping avoided, then track surfaces are no problem for either axle.
Has anyone experienced problems (with either axle type)when hard driving on public roads? I'm thinking specifically of hitting rough uneven surfaces, over a period of time.
Cheers
Tom
