Drewmotty 7 Report post Posted February 9 Looking at your picture posted earlier in the thread I can see that you don’t have the 4a/5/6 type trunnions and vertical links so all looks good there. 0 Share this post Link to post Share on other sites

The sidewall just protrudes at the front and is tucked in a bit at the rear camber is the standard +1 degree Edited February 10 by Drewmotty 0 Share this post Link to post Share on other sites
Ukmax 0 Report post Posted February 12 (edited) When visiting Stoneleigh at the weekend, I took the opportunity to measure the height to wheel arch on a couple of TR4s and was pleased to find that the measurement was the same (within a few mm) as that on my car. I am now happy with the ride height but I still have to square the body up properly on the the chassis to complete this part of the job. Thanks to all who gave such helpful advice. David PS. Andrew, I'm sorry but I missed your posts until I had posted this reply. Thank you for the confirmation re the vertical links, the height measurement and of course the photos Edited February 12 by Ukmax To add postscript 0 Share this post Link to post Share on other sites
Drewmotty 7 Report post Posted February 12 Hi David. How did your Stonleigh measurements compare with mine? 0 Share this post Link to post Share on other sites
Ukmax 0 Report post Posted February 12 Stoneleigh 'car 1" was 365 and "car 2" was 370mm, mine is also 365mm There are of course be potential errors caused by having to "best guess" both the exact wheel hub centre, the exact position (vertically to wheel centre) on the wheel arch from which the measurement is taken and the the exact profile of the wheel arch, so it is by no means a scientific test and errors could be <> 5mm or maybe more!.

rcreweread 4 Report post Posted February 12 David - - were your fulcrum mountings on the right way round? Cheers Rich 0 Share this post Link to post Share on other sites
Ukmax 0 Report post Posted February 12 Hello Rich, Good to meet and chat with you on Sunday. I haven't had time to check the fulcrum pins yet and I won't get back on to the job until next week but I'll let you know. David 0 Share this post Link to post Share on other sites
Ukmax 0 Report post Posted February 12 Rich, Because the car is up on the ramp with it's wheels on until next week, I didn't think I would be able to see the fulcrum pins but it occurred to me that I could photograph them with my phone. Both fulcrums are fitted the same way around as shown in the attached photo (Yes, I have new bushes to replace those!) I understood you to say that the fulcrum pins should be fitted the opposite way around to the "apparently obvious" way, i.e.with the concave side facing away from the shocker, therefore it appears that mine are the wrong way around.

rcreweread 4 Report post Posted February 12 David - that’s definitely wrong if your car was a 4A but I just have a nagging doubt that a tr4 was different to a 4A I’m sure someone will be along to confirm Not at home otherwise I would go and do same as you on my 4! cheers Rich 0 Share this post Link to post Share on other sites
Ukmax 0 Report post Posted February 12 Rich, I'm even more confused now! Image 3204.jpg is from the factory WS manual (2nd edition 1965) shows the fulcrum orientated with the concave side facing inboard which is the opposite way to mine. Image 3205.jpg is a drawing marked as TR4A in the same manual shows the orientation as being the same as mine. This seems to indicate the opposite of what you have just stated in your post. I'm not doubting you but since the fiasco over the distance piece above the spring, which is clearly shown as being present in this drawing, with no qualification as to the spring length, I'm beginning to have doubts about the accuracy of this manual.

Drewmotty 7 Report post Posted February 13 Yours are correct for a TR4. They were fitted the opposite way around on later cars. 0 Share this post Link to post Share on other sites
rcreweread 4 Report post Posted February 13 David To summarise then - for a TR4 , which you have, your fulcrum brackets are correctly fitted. For tr4As, they are fitted the other way round. Cheers Rich 0 Share this post Link to post Share on other sites
Ukmax 0 Report post Posted February 13 Thank you both. It seems that it is best to treat the manual as a guide to procedures rather than a "bible" because drawing E627 (which is marked on the other side as as being TR4A) is clearly not correct, unless only SOME TR4As had the fulcrum this way around. Andrew, I should have noted your footer "40 years of TR ownership and still learning!" !!! I've only had mine a few months. David 0 Share this post Link to post Share on other sites
