anthony1956 Posted October 22, 2019 Share Posted October 22, 2019 By which I mean get weak or otherwise lose specification, over 20 years.or can I just have them repainted and refit with serviced shocks?no part numbers apparent, nor specs so uncertainty governs at present.no one really seems to know.anthony Link to comment Share on other sites More sharing options...
rj Posted October 22, 2019 Share Posted October 22, 2019 They break over time - guess it's fatigue.My brothers Ford Granada from around 1977 had lowered itself over time without breaking the springs, so I guess they can grow old. Nowadays it's more common to break though. Link to comment Share on other sites More sharing options...
Phil G Posted October 22, 2019 Share Posted October 22, 2019 I would say yes. Like most ferrous items, they are subject to corrosion, wear and probably metal fatigue.I'm sure we have some metallurgist in the fold who can give a scientific answer.

auyt Posted October 23, 2019 Share Posted October 23, 2019 Older spring material definitely, you can have them reset/tempered that helps. But new springs seem to last longer due better steel allows. Link to comment Share on other sites More sharing options...
Simon.Rogers Posted October 23, 2019 Share Posted October 23, 2019 Most springs do grow old. There are very few with any warranty.The Hyperco brand does have a lifetime warranty. Link to comment Share on other sites More sharing options...
anthony1956 Posted October 23, 2019 Author Share Posted October 23, 2019 thanks all, any idea how to identify their spec? I guess that means "poundage"? Link to comment Share on other sites More sharing options...
anthony1956 Posted October 23, 2019 Author Share Posted October 23, 2019 I have found from the original Options list Race Dampers front & reardated 30 May 2000price n/c presumably "no charge" EDIT: and later invoice "Coil springs x 2 2.25ID-8-225 " Link to comment Share on other sites More sharing options...
EEK Posted October 23, 2019 Share Posted October 23, 2019 Well, once spring is removed, if you stand on it how much does it go down by? In that the rating, is required weight to compress the spring by 1 inch, well according to this it is https://www.knowyourparts.com/technical-resources/suspension/springs-and-suspenstion/ Link to comment Share on other sites More sharing options...

Technically that is the way to measure it (a spring tester does exactly this) but it sounds tricky to me. Link to comment Share on other sites More sharing options...
Bricol Posted October 23, 2019 Share Posted October 23, 2019 Take a drill press.A pair of bathroom scales.A steel rule. Place spring and rule vertcially on scales, the spring under the chuck. Zero the scale. Wind drill press down, compressing the spring a measured amount as seen on the rule alongside. Read the scales.Voila . . .Something on the scales under the spring to spread the load helps. Link to comment Share on other sites More sharing options...
garybee Posted October 23, 2019 Share Posted October 23, 2019 I was thinking about suggesting something similar with a cheap hydraulic press (bottle jack type) but thought he was unlikely to have access to one. I hadn't thought about using a drill press. As long as you're confident the spring has a linear rate I suppose you only need to compress it an inch. In that case you're only looking at about 100kgf and even a chintzy drill press should do. Link to comment Share on other sites More sharing options...
anthony1956 Posted October 24, 2019 Author Share Posted October 24, 2019 ok so wifey weighs 50kg (shh), we can balance her on top (as she is a dancer) and I can measure the compression? Link to comment Share on other sites More sharing options...

garybee Posted October 24, 2019 Share Posted October 24, 2019 I don't think 50kg is going to give you enough compression for an accurate calculation. You're only going to get about 1/2" of compression so any error in your measuring will be quite large relative to the travel. Never mind the hilarity you'd have trying to actually line a rule up with the top of the spring with someone's foot wobbling around on it. On second thoughts it's a great idea, can you post the video on here please? Link to comment Share on other sites More sharing options...

Area Representative Golf Juliet Tango Posted October 24, 2019 Area Representative Share Posted October 24, 2019 Take a drill press.A pair of bathroom scales.A steel rule. Place spring and rule vertically on scales, the spring under the chuck. Zero the scale. Wind drill press down, compressing the spring a measured amount as seen on the rule alongside. Read the scales.Voila . . .Something on the scales under the spring to spread the load helps. Excellent (if i owned a pair of scales, it would help).

Bricol Posted October 24, 2019 Share Posted October 24, 2019 Its the only reason I own one :) . Argos special from when I was trying to work out what I needed on the trials car.When you do own one - remember to measure the spring relative to the platform on the scales so you get the spring deflection only - not spring and scales.

anthony1956 Posted October 25, 2019 Author Share Posted October 25, 2019 missing the point dear taz, it's a question of what spec they arethough I think they are "race spec" from year 2000 - but we don't know what that is.and then to consider how to make it maybe less bouncy on uneven roads without affecting the handling in a disappointing way - anthony Link to comment Share on other sites More sharing options...
