Measuring Spring Tension (Take 3)

Ok, finally got around to removing the petrol tank in preparation for putting in the later Rover SPI tank for the fuel injection. I changed over the L/H spring and had time to measure the old one. Here is a picture of the spreadsheet showing there is very little difference between the previously measured R/H one .

Here is the updated Hydrolastic Helper Springs spreadsheet.


As previously mentioned, I feel that my old springs are not that old at all as the difference is roughly 5%. It would be good to get ¬†to measure a known ‘old’ spring to finally put this subject to bed.
