None of this discussion says which way to move the spring. I've never needed to replace a spring in a modern instrument, but in older ones (which sometimes arrive from eBay with broken springs), you have to push the spring backwards, as one end of the spring is larger than the other. This is designed to stop it coming right through the pillar and falling out, but it means there is no way you can grab the long end of the spring and pull it out - you have to push it back the way it came. But is this true in instruments being made today?
The worst job I ever encountered in this area was a spring that broke off right at the pillar (something I'm always nervous will happen when bending a spring to increase the tension). There was literally nothing sticking out either side to hammer. So I got the pillar out, put it in a vice, and used a carborundum centre punch on the stump. I could only make it protrude a fraction of a mm, but it was just enough to grab with pliars. It too ages, but the sense of triumph at the end was almost worth it.
