viperbl Posted June 27, 2013 Share Posted June 27, 2013 Hi Guys, Wondering if anyone can shed some light … Putting on some new Nitron Suspension. New bolts and new sleeves from Caterham, 99 Imperial chassis. The little suspension eyes slot into the suspension, tight fit … the sleeve goes into and through the eyes, again another tight fit with no movement. Then the bolt goes into the sleeve. Here is the problem, its loose. Not like a clowns pocket but a fraction of a MM which IMO is too much… See the below video for an idea of the play it passes on to the suspension. Caterham have sent me 4 new sleeves, same problem. I’ve tried other imperial bots… same prob. I’ve tried metric bolts and they are tighter but still not a fit I would be happy with. Anyone got any ideas? Thanks, rich Link to comment Share on other sites More sharing options...
NoLimits Posted June 27, 2013 Share Posted June 27, 2013 Rich There has to be something wrong from Caterham end. "Just" in case measure both the upper and lower bolts and they should be 5/16ths. I suspect they are sending you metric sleeves. Simon Link to comment Share on other sites More sharing options...
Roger Ford Posted June 27, 2013 Share Posted June 27, 2013 Are the bolts done up when you get that movement? Surely the bolts should clamp the sleeves, so it shouldn't matter if there's a bit of movement between the bolts and the sleeves? Link to comment Share on other sites More sharing options...
viperbl Posted June 27, 2013 Author Share Posted June 27, 2013 Bolts are done up tightly for test there. The top sleeves will actually clamp up and stop movement (although can’t say I’m 100% happy with this since under the load of the car etc its going to move…) The bottom bolt goes through the lower arm which is too thick for the bolt to move and clamp up… Simon, Caterham have replied that they have tested a bolt and sleeve and say while it’s not tight, it’s not “loose” … I suspect I should measure with vernier again but IMO it NOT tight, its loose! If I can move each end of the sleeve up and down on the bolt and see movement, that’s too much. Link to comment Share on other sites More sharing options...
NoLimits Posted June 27, 2013 Share Posted June 27, 2013 It is completely wrong. The bolts are a perfect match to the sleeves. I do not know if the bolt sizes have changed on the metric chassis - I thought they had. So I guess you have 8mm bolt sleeves not 5/16ths Try Redline.

viperbl Posted June 28, 2013 Author Share Posted June 28, 2013 Spoke to redline and they tested the batch they have from caterham, still had the same result, they said they tried an 8mm bolt also and got movement … faulty batch from caterham? Can’t believe this would be the first time its picked up?? Link to comment Share on other sites More sharing options...
Paul Deslandes Posted June 28, 2013 Share Posted June 28, 2013 unless you want to go round and round in circles with the inevitable conclusion (as in Oozlum bird), I'd take the bits down to a local engineering firm and ask them to make you a new sleeve with the correct tolerances. Shouldn't cost much and you'll be back on the road in no time. Link to comment Share on other sites More sharing options...
viperbl Posted June 28, 2013 Author Share Posted June 28, 2013 You have a fine point and I agree, could have had it done by now Link to comment Share on other sites More sharing options...
