Seat springs are uneven

[608KEB 795]

One seat spring is about 1/4" lower than the other one. Has anyone had this problem. If so, what'd you do to fix it?

[Achto 27,721]

I think that I would just stretch out the lower spring until it was the same height as the other one. May be use a port-o-power wedge to stretch it?

Could be you get on and off on the lower side and put more strain on it, switch them out and they will even out in about four decades.

May be an optical illusion but it looks like the lower spring is bent right above the mounting hole near the curved end. If it is a big hammer and an anvil should fix it right up.

I have a port o power wedge. I didn't want it to snap. I thought about heating it where it bends. I thought that might make the spring brittle. Um 953....I'll probably be dead in 40 years!

I would be looking for new springs, once spring steel is fatigued it could fracture at any time.  You also stress the seat with uneven support.

I've tweaked some of those in the past to make them more even with a large hammer and some heavy steel wedged inside - still running the same springs today and they are tougher than you think . I agree , one looks like it's bent slightly - if you wedge some plate next to that bend you can knock it straight again with a large hammer (4lb+) .

Heat will take the "spring" out of the spring.

If height isn't an issue, it's probably easier to squish the other one in a vice to make them the same height. Or, wedge and a hammer like others replied to open it up a little.

Thanks for the suggestions. I'll post the results.

I tried  a hydraulic  wedge that has a hand jack. That didn't work. I  found some other seat springs that are closer in height.  I'll use those.

I had a 520 with uneven springs.

They were uneven strength as well and you sat tilted all the time.

 

Bought a good used set of springs and all was well again.
