Grubbster Posted February 22, 2015 Share Posted February 22, 2015 Yesterday after much swearing I managed to get the old bush out (heating, hacksawing and bashing method) and today I'm trying to get the new one in.It is certainly an interference fit (as measured with digital calipers) so I froze the bush and heated the dedion where it goes in but couldn't even get it to start. So I filed a chamfer on the end of the bush and put a little greas on it to help get it started and managed to get it to start going in but it won't go. I tried pulling it in with threaded bar and socket, no joy, big G-clamp, no joy. The only thing that started to work was whacking it with a club hammer - this made some very slow progress but has damaged the end of the bush (I'll get another new one) so what else should I try? I hear of people changing these with the dedion fitted to the car - how on earth???? Or could it be that CC supply different sized bushes and I've got the wrong one? It measures 27.16mm diameter and the hole to put it in is 26.9mm - 27.2mm (slight ovality).Or how much is it for a new dedion - for the time I've wasted trying to do this that would have probably been better value!

F355GTS Posted February 22, 2015 Share Posted February 22, 2015 I had Arch fit a new one when re powder coating my tube, it always looked a nighmare job. Ideally you need to find somebody with a hydraulic press Link to comment Share on other sites More sharing options...
Grubbster Posted February 22, 2015 Author Share Posted February 22, 2015 Thanks Mark, this is another job I wish I hadn't bothered with! I'll find a local garage to press it in for me (once I've got a new one). Link to comment Share on other sites More sharing options...
Guy Lowe Posted February 23, 2015 Share Posted February 23, 2015 You need to buy yourself a NEW TOY Steve Link to comment Share on other sites More sharing options...
Dorset7 Posted February 23, 2015 Share Posted February 23, 2015 I'd say buy a new DD tube and save yourself the drama.............if Caterham had any in stock. Link to comment Share on other sites More sharing options...
stuart147 Posted February 23, 2015 Share Posted February 23, 2015 Hi Steve. Speak to Phil at Arch about refurbing the DD tube that you have. I had mine done a couple of months back and the quality of the finish is superb. They even suggested a way of getting it to them as I am a fair distance from Huntingdon. Very reasonable cost as well compared to the price of a new one. Send blat mail if you need more info.Stuart Link to comment Share on other sites More sharing options...
Grubbster Posted February 23, 2015 Author Share Posted February 23, 2015 Thanks for the tips, a new toy would come in handy! Yesterday I considered getting a new dedion but luckily CC don't have any so I saved a few hundred quid. I really wish I hadn't bothered trying to replace the bush, I don't think there was anything wrong with it but I thought it was straightforward and only a couple of quid so I thought it was worth doing while the dedion was out why did I bother??? I'll see if I can find a local place with a decent press. I'm very short of time and need to get the car back together in a couple of weekends so most of what I'd wanted to do just won't get done.

Ozzy Posted February 23, 2015 Share Posted February 23, 2015 Grubbster,Do you have access to a large vice? You need tension and shock, and it should go. Press it in a vice, tight as you can without using a lever on the vice handle, or you'll break the vice! Then with a large lump hammer or copper mallet, whack the vice jaw, and repeat tension as it starts to move. You also need someone else to hold the tube, as you don't want to drop it, once the bush starts to shift.oz Link to comment Share on other sites More sharing options...
Grubbster Posted February 26, 2015 Author Share Posted February 26, 2015 I think I've found the answer! It was obvious all along! Take it to Tom at New Techniques, he fixes everything I can't! Link to comment Share on other sites More sharing options...
