Quick answer: Preserve winding direction, setup datum, attachment geometry and approved operating turns alongside the part identification.

What reference information must a replacement part retain?
A mechanically similar spring may require a different setting procedure. Reusing an undocumented number of preload turns can change output and travel reserve. Service instructions should identify the correct assembly state and require restraint of stored energy before release.

A practical verification method
After replacement, verify initial torque, full usable travel and correct attachment engagement.
| Item | What to record | Purpose |
|---|---|---|
| Reference configuration | Part or assembly identity and drawing revision | Make comparisons traceable |
| Test conditions | Relevant position, direction and operating condition | Compare the same characteristic |
| Decision evidence | After replacement, verify initial torque, full usable travel and correct attachment engagement. | Resolve the specific question before approval |

Use the result in an engineering request
Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
