Paul McKenzie Posted October 12, 2012 Share Posted October 12, 2012 Isn't this clearance issue just the same as the reason why we all sawed the lug off the old Sierra diff? Link to comment Share on other sites More sharing options...
redlight Posted October 12, 2012 Share Posted October 12, 2012 So do we need half head bolts on the rear rather than full head ones? Link to comment Share on other sites More sharing options...
Alan Reeves Posted October 12, 2012 Share Posted October 12, 2012 I believe the bolts have a recess to fit into the new carrier as well . no further updates for me from CC Alan Link to comment Share on other sites More sharing options...
pmobbs Posted October 12, 2012 Share Posted October 12, 2012 CC have been in touch re my factory manufactured June 2011 Roadsport. The car had chisel-like 'witness marks' and dents in the De Dion tube. The brake pipe running on the top of this had been flattened. Earlier, I posted pictures of the De Dion and the brake pipe (see above). CC propose to install the new pattern carrier, new brake pipes of a different design and they have said they will do further checks on the tube. They seem confident that the new carrier will prevent further contact between it and the tube. I hope to collect the car next week. Link to comment Share on other sites More sharing options...
Alan Reeves Posted October 12, 2012 Share Posted October 12, 2012 Well one assumes they recognise the potential issues for all of us and will action accordingly. Thanks Link to comment Share on other sites More sharing options...
ParsleyTheLion Posted October 12, 2012 Share Posted October 12, 2012 Excellent news pmobbs. Looking forward to seeing lots of pictures of your reworked diff and De Dion. Based on email from James Gibson, I'm optimistic that CC are going to resolve this appropriately. Presumably, there are some logistical issues to sort out before they make some kind of public statement (like stock piling a significant number of new design level cages).

Oily Mick Posted October 12, 2012 Share Posted October 12, 2012 Meanwhile wait for some unsuspecting non-blatchat reading owner to have an accident? You don't need to have all the stocks and resopurces to fix the problem in order to warn customers. Link to comment Share on other sites More sharing options...
Grubbster Posted October 13, 2012 Share Posted October 13, 2012 I fitted my dedion into my new car today - I have the modified diff carrier. While t was just attached to the radius arms I lifted it to see if it could contact anything and it hit the diff casing before it was high enough to reach the countersunk bolts. I'll carry on bolting it in properly tomorrow and try again to see where it touches. Link to comment Share on other sites More sharing options...
Grubbster Posted October 14, 2012 Share Posted October 14, 2012 Fitted more to the dedion today, still if I raise it though it hits a little bit of casting that sticks out before reaching the bolts, so even if mine weren't countersunk I don't think the tube could hit them Link to comment Share on other sites More sharing options...
pmobbs Posted October 16, 2012 Share Posted October 16, 2012 Phoned today to see when my car would be ready - they have run out of carriers...... Link to comment Share on other sites More sharing options...
Alan Reeves Posted October 16, 2012 Share Posted October 16, 2012 but still silence on the issue from them in general? Link to comment Share on other sites More sharing options...
pmobbs Posted October 16, 2012 Share Posted October 16, 2012 Allan, yes, silence. Going away - will chase when I get back.... Link to comment Share on other sites More sharing options...
redlight Posted October 18, 2012 Share Posted October 18, 2012 It is 7 days since the James email, we are all waiting to hear what cc are going to do. How long do we leave it until we start asking again? Do we need to ask a little higher? Link to comment Share on other sites More sharing options...
adz Posted October 18, 2012 Author Share Posted October 18, 2012 James is currently out the office, I know because I tried to phone him yesterday. ( because his email inbox is full ) When my diff carrier failed it has allowed the propshaft to move forwards. My propshaft has been grinding on the tailpiece of the gearbox. The oil seal is now bust and I'm losing oil at a rate of knots from the gearbox tail. so it looks like diff out again to get to the oil seal. BUT, one of the threaded bosses on my carrier wasn't welded on straight and the bolt cross threaded when I bolted the carrier in. It''s torqued up, but I dont know how many times it's safe to keep bolting and unbolting it before the thread gives up. Joy joy joy. Adam Link to comment Share on other sites More sharing options...
Alan Reeves Posted October 18, 2012 Share Posted October 18, 2012 Well I am pretty sure they are reading this site and they still dont think its appropriate to speak out. I am going to drop the CEO mail today but previous dealings with him have not shown to much acceptance of inhouse issues. Link to comment Share on other sites More sharing options...
Alan Reeves Posted October 18, 2012 Share Posted October 18, 2012 done, would suggest that everyone drops him a line as well as James Link to comment Share on other sites More sharing options...
adz Posted October 19, 2012 Author Share Posted October 19, 2012 Well, I have to say hats off to CC for service. I told them about my oil seal woes, expecting at best to recieve a replacement seal ( self build car, out of warranty) The next day a van turns up to take the car away so that CC can replace the seal then deliver the car back again. So hurrah! Adam Link to comment Share on other sites More sharing options...
Graham Perry Posted October 19, 2012 Share Posted October 19, 2012 They probably want to have a look at the full mode of failure. It could start to get expensive if starts to do damage to the rear of the gearbox as well. Link to comment Share on other sites More sharing options...
1360rallye Posted October 19, 2012 Share Posted October 19, 2012 Just had a good look at the diff and cage in my Supersport (1800 miles, 2nd Diff installed at 1100 miles). No marks on the Dedion but both the bolts on the side holding the diff to the cage were loose (one was very loose). Tightened them both up and checked all the other bolts. Having already had an issue with a clonking first diff (and 2nd is only slightly better) which is irritating I'm really not happy to now to regularly have to climb under the car to make sure its not falling apart. Based on what I'm reading here I can't understand why CC aren't contacting owners. I will certainly be contacting them on Monday. Thank goodness for BC.

Alan Reeves Posted October 20, 2012 Share Posted October 20, 2012 ADZ, that is excellent news, have you had an update as to what they are doing with rectification and timeframe as we understood there are no Carriers? For all ,I have had a response from the CEO and the bottom line is that he will not commit to a timeframe for a fix? and will communicate when he is ready. I am with Andrew in this, why have they not been communicating with owners - unless like me they have they have complained. If they have a fix for race cars how come they do not have a fix for us roadies? Why do we have to chase when they should be leading this. Despite assurances that its not dangerous.....whose driving... I feel like Mr Grumpy old man...I have just had a lengthy discussion re the drip drip oil leak from the faulty oil seal when I built the car so I didnt need to get into another discussion but as we can all see - its major and affects a lot of people! Again bearing in mind this is on a very open forum you would think that they would be more proactive. The goods news is, SYD beckons for a few weeks.

redlight Posted October 23, 2012 Share Posted October 23, 2012 I find the whole situation very disappointing, I have taken the diff out four times now. I was hoping that the BMW diff was the solution but it just appears to be another problem. I have covered 2,800 miles in the 3 years from a new kit. I am still looking forward to just getting in the car and going for a drive without having to think is something going to go wrong. I, like others, wonder why racers get sorted and us roadies do not. Come on CC please sort this out. Link to comment Share on other sites More sharing options...
Roadsport06 Posted October 23, 2012 Share Posted October 23, 2012 Is the sierra diff going to be offered as an upgrade now Caterham: I have emailed you at two different email addresses (parts being one) about the temp sender lasting less than 12 months. You are still to reply. I then emailed saying that if I get no reply then my business goes elsewhere. It now looks like this is what I will be doing. Caterham, your poor communication is letting you down and you will be loosing people! Link to comment Share on other sites More sharing options...
adz Posted October 24, 2012 Author Share Posted October 24, 2012 Apparently I need a new gearbox and propshaft , I didn't think there was that much damage, but if CC are doing it then .... So this is turning into an expensive and time consuming repair, all for the sake of a couple of washers. adam Link to comment Share on other sites More sharing options...
DJ. Posted October 24, 2012 Share Posted October 24, 2012 Crikey, this is going to cost Caterham a fortune if all the cars need new props and gearboxes. It's got to be a good idea to recall them all asap! Duncan Link to comment Share on other sites More sharing options...
