Hamish Posted February 1, 2019 Report Share Posted February 1, 2019 I have bought second hand but not used a set of the bastuck adjustable top fulcrum kit would any of you have the English instructions. Same / similar to Revington kit I think. Google translate has helped but I could do with and English copy. H Quote Link to post Share on other sites
iain Posted February 1, 2019 Report Share Posted February 1, 2019 Hi Hamish Looks similar Revington kit. https://www.revingtontr.com/productimages/docs/ps0003-adjustable-upper-fulcrum-kit-5529389.pdf No fitting instruction there though Iain . Quote Link to post Share on other sites
stuart Posted February 1, 2019 Report Share Posted February 1, 2019 It looks to be the same as the Revington kit, basically fit it, adjust to required camber then weld it up. Im not overly keen on this kit but I know a few on here have fitted it. If you can find it I expect there is a set of instructions on Revingtons site somewhere though its a difficult one to navigate round. Stuart. Quote Link to post Share on other sites
iain Posted February 1, 2019 Report Share Posted February 1, 2019 Stuart i thought the same....cunningly they are not there! Out of interest and with no intention of ever using why don’t you like this kit? Cheers Iain Quote Link to post Share on other sites
Lebro Posted February 1, 2019 Report Share Posted February 1, 2019 (edited) FI018 ADJUSTABLE TOP FULCRUM KIT TR2-6.pdf There yer go. It's very fiddly to set up, lots of assembly, measure camber, dissasembly, adjust, assembly etc. Also due to not having captive nuts on the inner two locations in theory you need to remove the spring every time. I did manage to get a 3/8" socket + two extensions up the back behind the spring, but it was a right fiddle. probably much easier to shorten the upper wishbones, or fit the Racetorations version. I combined this with fitting late TR4 trunnions, & TR4A-6 upper wishbones, & swivel joint to give 3° castor, & also the Revingtons steering arms to improve ackerman angle. Having said that now it's on it works very well. Bob. P.S. mine came from the TR shop, & was described as being for TR2 - 4 in fact the bolt lengths were for a 4, & not correct for a 3 (too short) Edited February 1, 2019 by Lebro Quote Link to post Share on other sites
foster461 Posted February 1, 2019 Report Share Posted February 1, 2019 Revington has a link to an instruction sheet at the bottom of this description but the link is dead. Perhaps a call will spring it loose. https://www.revingtontr.com/productimages/docs/ps0003-adjustable-upper-fulcrum-kit-5529389.pdf Quote Link to post Share on other sites

Drewmotty Posted February 1, 2019 Report Share Posted February 1, 2019 (edited) Like Start I don’t like the design of the adjustable kit so I made a set of solid blocks to move the original fulcrum up 12mm and inboard 9mm Edited February 1, 2019 by Drewmotty Quote Link to post Share on other sites

That is my intended use as well. Can those with concerns share them. I would like to learn and understand the pros and cons. No wish to start any agro just learn Before fitting and use. Mine (if fitted) is on a 3a what do your blocks fit ? And what is the resulting geometry ? It looks like a neat, simple solution H Quote Link to post Share on other sites
Z320 Posted February 1, 2019 Report Share Posted February 1, 2019 You reduced the diameter of the head of the counter sunk bolts to realize only 9 mm inboard? Quote Link to post Share on other sites
Drewmotty Posted February 1, 2019 Report Share Posted February 1, 2019 Well spotted Z320. The offset is 14mm but the fulcrum is fitted reversed to reduce the offset by 5mm. The centre bar of the fulcrum then just misses the damper top mount by about 1mm. Quote Link to post Share on other sites

Mine (if fitted) is on a 3a what do your blocks fit ? And what is the resulting geometry ? It looks like a neat, simple solution H Revington/Bastick/Moss kit is adjustable allowing the camber to be set exactly to requirements regardless of the original geometry of the chassis and doesn’t require any personal poring over a CAD screen or drilling, tapping, sawing or filing in the workshop. But.... The overly long mounting bolts are unsupported for most of their length and the fulcrum pin is notched to clear the bolts The top wishbones are set further apart than standard to allow for spacers each side of the top ball joint This makes clearance around the fulcrum problematic and isn’t required if the original geometry is correct They cost quite a bit, they could do with a screw adjuster and they’re ugly. Blocks like mine only provide a minimum negative camber around minus 1 degree but can then be fine tuned by adjusting the top ball joint mounting holes in the wishbones. Bigger adjustments need a set of slightly different offset blocks making up. Quote Link to post Share on other sites

Drewmotty Posted February 1, 2019 Report Share Posted February 1, 2019 (edited) Shorter top wishbones will certainly provide the required negative camber but don’t address the problem of the virtual roll centre being too low and will also compromise the camber gain. In real terms I don’t think that on our relatively narrow tyres that amature enthusiast drivers like the majority of us will notice any difference. We would probably be better off spending our money on track instruction and rolling road setup both of which will certainly make us faster. :-) Edited February 1, 2019 by Drewmotty Quote Link to post Share on other sites

In 2013 I made a sketch of the falcrum pin for the german TR forum to illustrate its offset. I determined it about 2,25 mm, but it could be 2,50 mm.

stuart Posted February 2, 2019 Report Share Posted February 2, 2019 TBH I didnt like it for a variety of the above answers, I would if going down that route use the Racetorations setup every time. http://www.racetorations.co.uk/triumph-c56/tr2-c3/tr2-chassis-suspension-and-steering-c76/racetorations-upper-wishbones-adjustable-p425 Stuart.

Ian Vincent Posted February 3, 2019 Report Share Posted February 3, 2019 Hamish, it probably depends on how you are going to use the car. I fitted The Revington kit and found it pretty straightforward to follow their instruction sheet. And the kit itself was a reasonable price. Thr trickiest part for me was tack welding the top plates so that I could remove them and weld them up properly. Rgds Ian Quote Link to post Share on other sites
