Seat height spring install
 

I removed the spring that adjusts height to remove my driver seat in my 250s

Any tips to reinstall before I try to rig something?

I think it is the same on the R107. I had to make a small hole to use as a lever point to stretch the spring into place. I know not the best, but not many choices there. I suppose, a spring expanding tool of some sort could be made. I didn't think of that before now. It's not a light duty spring.

Thanks. I did the coin trick and it stretched the spring enough.
