Quick answer: Check contact location, retention and local geometry under the approved winding conditions. The arbor slot and spring end form one load-carrying interface.
What needs inspection at the inner attachment?
A slot that accepts the hook during assembly may still concentrate load at a sharp edge. Slight positional changes can create rubbing or inadequate engagement. Review the mating drawing and inspection access rather than approving only the spring-end shape.
A practical verification method
Inspect engagement before and after representative cycling; record movement, local marks and any change in torque.
| 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 | Inspect engagement before and after representative cycling; record movement, local marks and any change in torque. | 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.
