Jase Posted December 22, 2020 Report Share Posted December 22, 2020 Had a quick search and couldn't find any information. Does anyone supply these? I'm about to replace my front verical links with Canley Classics kit: https://www.canleyclassics.com/?product=trunnionless-front-suspension-kit Had a link/trunnion fail on me many years ago and not keen on it happening again. Firstly, is this a problem on the 4A and secondly is there a similar replacement for the 4A? Thanks and Merry Christmas Jason Quote Link to post Share on other sites
BlueTR3A-5EKT Posted December 22, 2020 Report Share Posted December 22, 2020 Sadly not an item redesign like that offered commercially for the TR range. The Spitfire GT 6 set up is common to Caterham 7 Peter W Quote Link to post Share on other sites
DaveR Posted December 23, 2020 Report Share Posted December 23, 2020 Originally available in the 1960's for Herald, Vitesse, Spitfire, GT6 and Bond. Was mainly aimed at the later Lotus 7. The Herald based front wishbone suspension is different than the TR2-6 set up. Dave Quote Link to post Share on other sites
RogerH Posted December 23, 2020 Report Share Posted December 23, 2020 Hi Jase, as you have found, Canley Classics do a very good kit for the small chassis cars but not for our mighty beasts The failure point on the Vertical Links is the thread run-out on the bottom where the Runnion screws in. This is caused by rusty corrosion/pitts. Keep the trunnion well greasd (annually) and if every you can see the thread run-out check for rust and corrosion. If there is ANY rust/corrosion then change the VL. There are pics on here but I can;t find them with the search facility Roger Quote Link to post Share on other sites

This is caused by rusty corrosion/pitts. If you'll forgive me for clarifying, that may be true for TR (although it is quite rare for TR's to suffer this failure), but not for small chassis Triumphs. They can break at any point in their life and the Canley Classics conversion is highly recommended. After breaking a new GT6 one, I had the next set tuftrided. One of those also broke.

RogerH Posted December 23, 2020 Report Share Posted December 23, 2020 Hi Jerry, indeed I was only commenting on the TRs. The small chassis items must be very weak design. Roger Quote Link to post Share on other sites
stuart Posted December 23, 2020 Report Share Posted December 23, 2020 I believe they did consider doing this for the TR range but it was thought to be too expensive a conversion as it would involve a complete lower suspension arm /upright kit. Stuart. Quote Link to post Share on other sites
Jase Posted December 23, 2020 Author Report Share Posted December 23, 2020 Thanks, interesting to know, as above I had one failure and as the Spitfire is resting for long periods I'd rather fit something a little safer. Quote Link to post Share on other sites
roy53 Posted December 24, 2020 Report Share Posted December 24, 2020 i know that 2 full race TR4s had this type of trunnion removal in the 80s . They were welded onto standard uprights. 1 is still racing but not sure if it still uses the ball joint. Roy Quote Link to post Share on other sites

Standard Triumph always stipulated oil and not grease in these trunnions for that reason, though many have had grease applied over the years. Well that's the history, take away what you want from it. I suspect there are a number of causes and the use of grease is one of them. Happy Christmas, Dave Quote Link to post Share on other sites

Roger Phil Tucker uses small chassis suspension on the front of his trials TR3 so it's certainly capable of taking an awful lot of abuse despite the flimsy appearance. i think that it just shows how overbuilt the standard TR really is.

Drewmotty Posted December 27, 2020 Report Share Posted December 27, 2020 The chassis is much modified and goes over the axle at the rear. Why use the small chassis front end......no idea but I’ll ask. Quote Link to post Share on other sites
Nigel C Posted December 28, 2020 Report Share Posted December 28, 2020 years ago my mate was running a scimitar (which have the same VL) and he machined the VL and the trunnion so it was a smooth fit, no thread and then he secured it through the grease nipple thread....he's still alive.....don't know if the car is..........just sayin....don't shoot th.......
