Quick answer: Define assembly setting, usable travel and prohibited end regions separately. Total possible winding is not a safe working-turn specification.

How should working turns be separated from total winding?
The spring must retain an approved operating window after preload and adjustment. More material or an additional turn cannot be assumed to create useful travel without checking stress and geometry. Show the starting and ending arbor positions on the assembly instruction.

A practical verification method
Confirm the most extreme setup still leaves the required approved operating window before mechanism stops are reached.
| 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 | Confirm the most extreme setup still leaves the required approved operating window before mechanism stops are reached. | 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.
