Gromit Posted May 22, 2008 Share Posted May 22, 2008 I've a vague recollection that someone tested a bunch of CVs to see at what torque the gave up at, and where they broke. I remember the results favouring the after-market ones, as they were stronger and broke more cleanly. Who tested them, was it Si? Anyone got the results?

Mark Posted May 22, 2008 Share Posted May 22, 2008 I think it was either Si, or Ashcrofts or a collaboration between them... Quote Link to comment Share on other sites More sharing options...
Ivan Posted May 22, 2008 Share Posted May 22, 2008 I know Ashcrofts were showing the difference between their uprated CV and a standard CV at Billing last year. Maybe email Dave for details ? THT Ivan Quote Link to comment Share on other sites More sharing options...
Steve Hiatt Posted May 22, 2008 Share Posted May 22, 2008 Yes, it was Ashcrofts and the results showed that Paddock ones were stronger than genuine ones. However, I had four paddock ones, of various ages, in the lathe last weekend (don't ask) and the hardening was completely different on a couple of them. One pair machined like ali, one pair made stainless look easy. As is my wider experience, it's pot luck on quality with Paddock. Quote Link to comment Share on other sites More sharing options...
ashtrans Posted May 22, 2008 Share Posted May 22, 2008 it was us, this is the test rig : video will try to post the results tomorrow, Quote Link to comment Share on other sites More sharing options...
ebdesignDEFENDER Posted May 22, 2008 Share Posted May 22, 2008 What CVjoint manufacture was tested in the video? 700 is a good result? Quote Link to comment Share on other sites More sharing options...
ashtrans Posted May 23, 2008 Share Posted May 23, 2008 Hi, just added this from the web site, CV data graph all tested at 30 deg, this shows : blue, short front 32/24 genuine shaft with genuine late 32 sp CV, CV failed at 3712 ft/lb pink, short front HD 23/24 shaft with genuine 2522 CV, CV failed at 4154 ft/lb turquoise, short front HD 23/24 shaft with pattern cheapo 2522 CV, CV failed at 4242 ft/lb red, short front HD 23/24 shaft with HD 2522 CV, SHAFT failed at 5745 ft/lb note on the last one the shaft failed not the CV !

will_warne Posted May 23, 2008 Share Posted May 23, 2008 Be aware if you plan on running aftermarket cheapo 23/24 spline CVs (AEU2522's) they do tend to go on the stub shaft as the testing suggests. This is what I used to run and I've had this sort of failier blow the ends of the stub axle outwards making it impossible to get the hub nuts off (had to split them in the end). It doesn't always happen but its a pain when it does. It does mean you can continue to drive (unlike a failer at the bell which often locks the steering) but the repair will be more involved. Ashcorft's CVs solved all that - superb bits of kit!!! (You can send the cheque to the usual address, Dave ) Quote Link to comment Share on other sites More sharing options...
Escape Posted May 23, 2008 Share Posted May 23, 2008 Do you also have figures for the HD replacement late CVs you sell? I would be interested to see how they compare. Thanks, Filip Quote Link to comment Share on other sites More sharing options...
