Phil Read Posted April 22, 2020 Report Share Posted April 22, 2020 I am about to start removing the front and rear wings. I have been soaking the screw headed bolts, under the wing with WD40 every day for the past week. Unfortunately I cannot shift the bolts even with and impact screw driver. Short of drilling them out or grinding the heads off has any one any tips? Quote Link to post Share on other sites
Ian Vincent Posted April 22, 2020 Report Share Posted April 22, 2020 Mine wouldn't shift either but they are easy enough to drill out. I had to replace the whole boot channel anyway as it was rotted through. Rgds Ian Quote Link to post Share on other sites
stuart Posted April 22, 2020 Report Share Posted April 22, 2020 You need to use a better penetrant for one and get it into the captive nuts under the wings and wait a bit longer. You may need some heat as well but in the end its often easier to grind the heads off and or drill them out. Stuart. Quote Link to post Share on other sites

Give it a go and then leave it there. PlusGas and Freeway are very good penetrating fluids. However your screws and captive nuts have been welded together by rust. Unless you can break the rust bond then drill out looks like the last solution. I do use WD40 to help undo screws/nuts etc that are stiff but not frozen in place. It works as a reasonable temporary lubricant. But it is a wonder fluid. Roger Quote Link to post Share on other sites

foster461 Posted April 22, 2020 Report Share Posted April 22, 2020 On my car the bolts and nuts were irreversibly welded together with rust. You could soak them until doomsday and nothing was going to free them. Not just the rust but the feeble cages allowing the nuts to rotate is working against you. I ground off the heads, then pried the remains out of the cage. For the door hinge screws I drilled them out. I was able to free a few of them in the vice with some heat. It is worth salvaging as many square nuts as you can as the repro ones are a little undersized. If you dont care about originality there are modern UNF cage nuts that are much better made. My biggest harvest of square nuts was from the floors where they had been soaked in oil for 50 years. Stan Quote Link to post Share on other sites
Ian Vincent Posted April 22, 2020 Report Share Posted April 22, 2020 Alternatively, buy some flat steel bar and make your own cage nuts. Rgds Ian Quote Link to post Share on other sites

foster461 Posted April 22, 2020 Report Share Posted April 22, 2020 I tried making SS nuts from SS bar stock. The stainless is very hard and brittle, took forever to cut and drill and I broke several taps trying to cut the thread before I gave up. Quote Link to post Share on other sites
Ian Vincent Posted April 22, 2020 Report Share Posted April 22, 2020 Stainless steel work hardens very quickly when you are drilling or cutting it. Rgds Ian Quote Link to post Share on other sites

Yes but having restored a lot of them theyre no easier to take apart after fifty plus years! plus with the steel to ally electrolytic reaction between wings and shrouds you dont often have to bother undoing them as they just pull off in a cloud of ally dust Stuart.

Phil Read Posted April 23, 2020 Author Report Share Posted April 23, 2020 Sounds as though I am going to have fun. When refitting wings is it possible to just use nuts and bolts or screws and spire clips as on the TR6? I am not doing a concours job. Quote Link to post Share on other sites

No because you cant get to half of them from behind very easily, you may as well do it properly first as last. Stuart. Quote Link to post Share on other sites

Stuart. But what about spire clips Attached to the wing edge instead of captive nuts? You could then use flathead screws which would look like the original. Land Rover used them to replace the captive nut idea. Quote Link to post Share on other sites
