PlastererPete Posted December 5, 2023 Share Posted December 5, 2023 Just need a sanity check please. I'm replacing the carbon front wings on my 2005 CSR and I've managed to get one of them off this evening. The other one, the allen head bolt does not want to shift, so soaking it in WD40 for a couple of days and praying it doesnt round over 🤞. Can someone just confirm that it's an M8x20 bolt to fix it to the lower front stanchion? I'm getting an order together from Accu and wanted to confirm before pulling the trigger. Thanks all.

Member Jonathan Kay Posted December 5, 2023 Member Share Posted December 5, 2023 I recommend using a penetrating fluid such as PlusGas rather than ordinary WD-40,. Jonathan Link to comment Share on other sites More sharing options...

SamC Posted December 5, 2023 Share Posted December 5, 2023 Hi Pete, I did the same last year and had to drill them out. The thin web just locked the bolt and nothing I could do (plusgas/heat etc) free’d it. I replaced it with one of accu’s black stainless fasteners, a penny washer and a nut on the wheel side. This needed me to grind a flat into the inner edge of the wing stay prior to powder coating. I then trimmed the bolt to be just protruding from the nut.

PlastererPete Posted December 5, 2023 Author Share Posted December 5, 2023 Don't say that Sam 😅 I'm already nervous everytime I do something to the car knowing my dad would never have done any work on it himself. I'll try the plusgas route, and anything else I can find that might free it. One good thing, is I have all winter to do it 😄 1 Link to comment Share on other sites More sharing options...
Dan R Posted December 5, 2023 Share Posted December 5, 2023 I have heard of an innovative way of releasing stuck bolts etc by using wax. It appears to be as simple as applying some heat and then applying some simple wax like a 'tea light' and allowing that to penetrate. I have not tried this myself but have heard it anecdotally on a few occasions with supposed good results. Link to comment Share on other sites More sharing options...

Heat is your friend too. Not heard of the wax method, but that could be one to try too. Link to comment Share on other sites More sharing options...

See: https://www.caterhamlotus7.club/forums/topic/273938-new-website-feedback-and-ideas/page/5/#comment-2598847 I logged the problem. I can't see an acknowledgment or list of options or suggestions for workarounds. I've reposted in that thread. It would still be helpful to know what happens with other browsers (As in the strange issue of inline PDFs on the old software.) Jonathan Link to comment Share on other sites More sharing options...

I'll have a look. Do you already have the specific CSR documentation? I think that you have the bolt from the other side... what's the length below the head and the diameter? Thanks Jonathan Link to comment Share on other sites More sharing options...
PlastererPete Posted December 6, 2023 Author Share Posted December 6, 2023 Yea ive got all the manuals and extra paperwork for the CSR specific bits. I read through everything to do with front wings and couldn’t find the answer. The measurements come up a hair under 19mm length and 7.87mm diameter. I’m assuming its a metric M8 allen head bolt but being a 2005 chassis I wasn’t sure if it would be Imperial. Link to comment Share on other sites More sharing options...
PlastererPete Posted December 7, 2023 Author Share Posted December 7, 2023 Had a go at the stuck allen bolt after giving it numerous doses of Plusgas (great stuff i wish I had heard of years ago) and after some 15stone careful leverage the bugger, thankfully, undid. 1 Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted December 7, 2023 Member Share Posted December 7, 2023 Well done. I'm pretty convinced about the superiority of penetrating fluid, but I wish that the evidence was better. There is a video with a comparative test somewhere but the experimental design wan't great. Jonathan Link to comment Share on other sites More sharing options...
