I am refurbishing a front shock absorber, with all parts off the car, and intend to make a trial fit/check for stiffness before re-fitting to the car (which is a 1934 4 Seat Tourer). It would find it useful to have some idea of the stiffness I should expect, or perhaps I should say the range of stiffness obtained, as the adjusting nut is wound in.
All the articles I have seen simply offer the idea of making adjustments to suit the ride, which is a bit bland. I prefer to talk numbers, so with the centre support bracket clamped in the vise I am hoping to learn what sort of load can be resisted when pulling on the end of either arm. Can anybody help? Is it all documented somewhere, 'cos I can't find it!!
I should add that the two outermost arms were found to be slightly concave; but this was enough to allow contact with the friction disc only at its outermost part, to show a ring of blinded disc some 3mm wide - the rest had never been in contact! Nipping a disc against an outer arm with finger and thumb a allows a feeler gauge to be inserted from the centre towards the periphery to explore this concavity. After some effort with a belt sander, the arms are now much improved.
