For example, low headroom garage doors often have cable drums on the outside of the end plate and the torsion springs usually wind down rather than up. They normally have left wind springs mounted on the left side of the spring anchor bracket and right wind springs mounted on the right side of the bracket. The first part on the shaft beyond each torsion spring is the end bearing plate. Just beyond the end bearing plate is the cable drum. On these the cable often runs on the front of the cable drum. The bottom of the cable is attached to a bracket that wraps around the front of and outside the vertical track.

The technician, Robert Helton, was very pleasant, helpful, and professional. He repaired the garage door opener expeditiously and explained why it hadn't worked properly. He also checked the chain mechanism and the door itself and showed me how to manually work the door should I need to do that in the future. I was very pleased with this repair work.
In most cases, only one spring breaks or wears out at a time, and you can get away with replacing just the failed spring. But this is a little like replacing old car tires one at a time. You'll get the best performance if all the springs are new and have the same strength. Extension springs are replaced individually, making it more tempting to replace just one. With torsion springs, you have to disassemble everything to replace either spring, so it makes sense to swap out both springs during the repair.
