John L Posted October 19, 2021 Report Share Posted October 19, 2021 I have a Duck material soft top, when its up there seems to be a lot wind noise created by the header rail, I think? It doesn't leak water in. The rubber seal is in good condition. So a couple of questions, should there be a seal between the header rail part 713021, or is it just some window sealer underneath? The header rail is attached to the side rail by a rivet, and a washer, where does the washer go? should it go between or underneath, and should that fixing have some looseness, if I refit with a nut and bolt?

RogerH Posted October 19, 2021 Report Share Posted October 19, 2021 Hi John, this may not help - many years ago a friend up in Scotlandshire gave me a piece of double glazing rubber seal. it has a triangular cross section. On my Surrey top TR4A with the top off the seal tucks under screen frame top cap - it removes the wind noise dramatically. With the surrey top roof in place the gap is reduced significantly. No space for the seal but the noise is reduced. So how big is the gap between the top cap and the screen frame. Can a seal be pushed in. Roger Quote Link to post Share on other sites
harlequin Posted October 19, 2021 Report Share Posted October 19, 2021 John On my list of things to sort out this winter is to reduce the wind noise coming from the TR6 header rail on my Surrey top, so I shall follow this thread closely George Quote Link to post Share on other sites
John L Posted October 19, 2021 Author Report Share Posted October 19, 2021 Hi Roger, I could try your friends idea as well, I was going to try some duck tape along the gap to see what difference it would make, there are a few gaps between the aluminium strip and the frame, I was thinking of taking out the rivets and putting in some windscreen sealer.

Scaf Posted October 19, 2021 Report Share Posted October 19, 2021 I like your idea of duck tape, that way you will be able to track down exactly where the noise is coming from and go from there. Quote Link to post Share on other sites

I had TRs when they were new and the TR6 was fairly quiet certainly quieter then most saloons of the day, so in my case definitely room for improvement George Quote Link to post Share on other sites

The TR4/4A Surrey has a rail that protrudes way past the window seal - but is needed to hold the roof fabric. The 4A - 6 convertible style is much shorter and should have less wind noise.

John L Posted October 20, 2021 Author Report Share Posted October 20, 2021 The capping on my screen is this, originally it had a surrey top, there is quite a gap at the sides where the capping fits the screen surround. I think I need to take the rivets out and seal up underneath the capping. Quote Link to post Share on other sites

Roger Roger My car is a TR6 and the top of the screen frame is as it came from the factory. I modified the soft top for my Surrey set up by unpicking the front seam and removing the flat bar that hooks under the top of a TR4 screen frame and fitted a TR6 header rail, this works well its very easy to fit and is watertight, but the wind noise has increased. The Surrey soft top has a beaded leading edge which looks right but I suspect its that that is causing the noise, so my first port of call will be to remove the TR6 header rail, unpick the beaded edge and refit. Hopefully this will give a cleaner leading edge, I am also going to look at the angle of the header rail when it is locked to the screen frame and maybe fit a seal to the trailing edge to bring the front down.

John L Posted October 20, 2021 Author Report Share Posted October 20, 2021 George I do get a noise when the top is down, but was more thinking it was either the waterpump, the alternator, or the vented disc's whistling, will block it off with some tap and see if I still get that same noise, that will eliminate one of the noise sources. Weathers not so good for the top down at the moment, will try when possible. John Quote Link to post Share on other sites

keith1948 Posted October 21, 2021 Report Share Posted October 21, 2021 Try adjusting the windows down a fraction. My 4A whistles with the surrey top up when the passenger window is fully up but doesn't if it is a fraction lower. The drivers side is ok. You could also try pushing some draught strip under the lip of the header rail when the hood is up to see if that improves things. Experiment with tape to find the location of the whistle before removing header rail. The whistle on mine is definitely at the passenger end. Keith Quote Link to post Share on other sites

All that was involved was to put a washer under the fixing handels at each screw location, this moves the handels down by 1 or 2 millimeters which is enough to securely clamp the header rail seal. It's a new seal but obviously not quite as thick as the original. Hope this helps you George Quote Link to post Share on other sites
mike3md Posted November 1, 2021 Report Share Posted November 1, 2021 As well as using a strip of rubber glazing gasket to great effect under the front lip of the header rail on my TR4 like Roger does, I also fashioned a couple of small plugs for the 2 surrey fixing holes in backlight top section. This has more or less eliminated another source of noise when the surrey top is in the boot, as the rushing (well, it is a TR) air passes over the top of the backlight frame.

The washer goes on the rivet first and the closing of the rivet faces underneath and my header is slightly loose but one has to remember that the fixing is 48 years old! Hope this helps. I cannot take a photo to show you more! Bruce. Quote Link to post Share on other sites

John L Posted November 8, 2021 Author Report Share Posted November 8, 2021 I've now taken the the top rail off, and I think its not very pretty under there. It seems to have been done before perhaps, as there is some softish putty like material and some hard black sealer, unless the putty material has just gone hard. Also the original holes in the screen frame have not been used, and some new ones made, think this must have been done at the factory? So what's the best to put it back on with, I suppose some windscreen non drying material, just in the gully of the capping at the front presume, any recommendations pls. Is Tiger seal will set too hard presumably? John Quote Link to post Share on other sites
stuart Posted November 8, 2021 Report Share Posted November 8, 2021 Clean it all off and use some non setting windscreen sealant is best. Stuart. Quote Link to post Share on other sites
John L Posted February 22, 2022 Author Report Share Posted February 22, 2022 Well re fitted the capping strip with some windscreen sealer, but still have the same amount of noise, no air coming in or water, it just seems that the windscreen rubber that is quite proud and the lip of the hood is just not aero dynamic, is the seal I have the correct one, perhaps there is a better one? Should the header rail be a loose fit to the side rails? Anybody got a picture of theirs...... John Quote Link to post Share on other sites
BlueTR3A-5EKT Posted February 22, 2022 Report Share Posted February 22, 2022 (edited) I recall the TR Workshop in Lexham Mews used to buy the Spitfire 1500 header rail seal. As they only worked on TR s……..???? The Spitfire screen capping is almost identical to the TR. Here is a view and it’s cross section is shewn in the picture too. Fits in the C channel same as the sponge thing on TR. http://www.leacyclassics.com/629584.html Edited February 22, 2022 by BlueTR3A-5EKT Quote Link to post Share on other sites
Martin50 Posted February 22, 2022 Report Share Posted February 22, 2022 John, couple of pictures of mine. No work done on it since I’ve had it but probably was rehab back in 1990’s. I don’t get much wind noise but general noise from engine, tyres, road etc. Windows up makes a big difference to noise as well when top up. Quote Link to post Share on other sites
John L Posted February 22, 2022 Author Report Share Posted February 22, 2022 Thanks Martin, mine just doesn't seem to want to sit nicely like yours, it may be the screen rubber is not quite right, that has never been out, perhaps that has to be done? Should the header rail be a loose fit to the side rails, mine doesn't have the original rivets, now bolts, and no washers between the header rail and the side, as in the Moss parts book.
