TRnorm Posted March 29, 2015 Report Share Posted March 29, 2015 I didn't pay too much attention when I fitted the windscreen. But now I see that I have a small clearance (at the top) between leading edge of window and the windscreen frame. And I have a much larger gap lower down. I appreciate that it may be the tilt of the window, but at the B post area, the edge of the window seems nice and parallel with the vertical line of the hood. So, is there adjustment to the windscreen frame such that its tilt can be "adjusted"? I could of course slacken the frame and find out but would like to save myself wasted effort if I find no adjustment is possible. Thanks for any suggestions.

RogerH Posted March 29, 2015 Report Share Posted March 29, 2015 Hi Norm, if you slacken the bracket that holds the screen frame leg then there should be a small amount of movement. This may be worth attempting.. Roger Quote Link to post Share on other sites
TRnorm Posted March 30, 2015 Author Report Share Posted March 30, 2015 Thanks Roger Norman Quote Link to post Share on other sites
Vic787 Posted March 30, 2015 Report Share Posted March 30, 2015 Same here Norman I did the same and attempted an adjustment as suggested by Roger. By loosening the bolts on the legs of the screen frame in the A post some adjustment is allowed but no matter how hard I tried I am still left with a wider gap at the bottom than at the top but the windows close on the rubber seal. I took photographs throughout the rebuild but unfortunately none with the windows up originally. Vic Quote Link to post Share on other sites
RogerH Posted March 30, 2015 Report Share Posted March 30, 2015 (edited) Hi Norm/Vic, there is also some adjustment on the centre pivot of the regulator. Remove the door card, the nut in the middle will allow the regualtor to move up/down a fraction when slackened. Anotherare of concern is - have you got the correct glass. The TR4/4A are different from the 5/6. The bottom edge has a different angle. If the back of the glass is in the correct place but the front is wrong then it is adjustment you require. If the back is in the wrong place then you may have the wrong glass. Roger PS - have you taken measurements from the top of the screen frame to the 'B' posts on either side to see if there is a misalignment.

TR 2100 Posted March 30, 2015 Report Share Posted March 30, 2015 I took photographs throughout the rebuild but unfortunately none with the windows up originally. Vic Vic, Photos would have likely shown you that the original fit was not all that good. AlanR Quote Link to post Share on other sites
TRnorm Posted March 31, 2015 Author Report Share Posted March 31, 2015 As always, much food for thought, and good to know Its not just me! My plan for the WE then is to take the measurements as suggested. Then see what adjustment to the frame might accomplish - now I know there should be some adjustment. The glass shows quite a bit of wear and tear, and although not proof positive, suggests it's original. So, many thanks guys. Norman Quote Link to post Share on other sites
AlanT Posted March 31, 2015 Report Share Posted March 31, 2015 Try slackening the nuts that hold the screen-frame into the brackets. The tighter you do these the more the frame will tip backwards. You don't say how much more gap you want. 3mm is easy, 12mm is impossible. Quote Link to post Share on other sites
stuart Posted March 31, 2015 Report Share Posted March 31, 2015 The nuts on the bottom of the tubes do not make any difference to the angle of the frame. All they do is draw the frame down into the position that is determined by the angle of the brackets that are bolted to the inside of the "A" posts. Its the adjustment on them that you need to concentrate on to get the angle right. Stuart. Quote Link to post Share on other sites
MikeF Posted March 31, 2015 Report Share Posted March 31, 2015 Every Triumph I've ever had had this problem! But I relieved it to a large extent on my present 4 by renewing the window lifters, the drivers door side was almost toothless and had slack in all directions, passenger side not so bad. The pivot pins were also worn out and I made new ones. Mike Quote Link to post Share on other sites
mjdearing Posted March 31, 2015 Report Share Posted March 31, 2015 We had this a few weeks ago working on Pete Moffatts 5 try this, Remove screen frame and take rubber off refit frame you can get the angle perfect even with bottom bolt tightened, remove frame again fit rubber and try again screen now pulling itself rearwards at the top, new rubber is thicker harder than original and when tightening the bottom bolt once the rubber starts to compress the screen starts to lean rearwards. So undid all screen bolts cut 3"x3" timber and fit between screen top and rear seat squab adjust timber till screen is slightly more forward at top than needed bolt up brackets tight but not bottom bolt,remove timber nowt should move shut door with window up now start to tighten bottom bolts soon as screen starts to move rearwards stop that enough. This took hrs and hrs so just passing on what we did may be worth a try Norm. Quote Link to post Share on other sites

Geko Posted March 31, 2015 Report Share Posted March 31, 2015 the easiest way to get a "decent" windscreen tilt adjustment - say up to 10 mm- is by elongating the holes in the A posts Quote Link to post Share on other sites
TRnorm Posted April 2, 2015 Author Report Share Posted April 2, 2015 Just want to say Thanks for all the advice and experience - although having taken my car for its maiden longish trip of 250 miles yesterday I find i have a more pressing problem! I wont go off topic here, but suffice to say it has really bad vibration at more than 40mph that needs sorting mega urgent. Window gaps will have to wait awhile, but info gratefully logged into the few remaining grey cells. Norman Quote Link to post Share on other sites
rob@robmorgan.plus.com Posted June 7, 2016 Report Share Posted June 7, 2016 Had the same problem with USA import, Reason is that a lot of guys pull on the frame to get out of the car and over time actually bend the frame. I has to Jack out the frame. Quote Link to post Share on other sites
boxofbits Posted June 7, 2016 Report Share Posted June 7, 2016 I noticed that when I purchased new door glasses some years ago the angle of leading edge door glass to windscreen frame wasn't as good as the original. Like Roger said, I did manage to get some adjustment on the regulator but not perfect. Unlikely to be screen frame angle I would have thought. Kevin Quote Link to post Share on other sites
RogerH Posted June 7, 2016 Report Share Posted June 7, 2016 Hi Kevin, that would have been a TR6 window - TR4/4A windows not available at the time. They are now. The bottom edge of the glass is at a different angle. Roger Quote Link to post Share on other sites
boxofbits Posted June 7, 2016 Report Share Posted June 7, 2016 Thanks for that Roger - I never realised that. I think I will get them changed in that case at some point this summer. Is that from Moss? Kevin Quote Link to post Share on other sites
