Spring Overtravel Evidence from Stop Marks

Quick answer: Inspect stops, attachments and retained material for evidence of movement beyond the approved window.

How can overtravel be investigated without reproducing damage?

A damaged end alone does not prove overtravel. Compare reference positions and consider stop deflection or assembly setting. Avoid deliberately repeating uncontrolled overload as a diagnostic shortcut. Use the documented operating limits and preserved physical evidence.

A practical verification method

Check the actual end positions against the approved drawing and correlate marks with the recorded motion history.

ItemWhat to recordPurpose

Original verification plan for this specific decision. Acceptance values must be agreed for the actual product.

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.
