Spring Mechanism Diagnostics

Link the observed symptom to evidence that supports a cause and explains why plausible alternatives were rejected.

Align datum, direction, speed, fixture geometry, conditioning and units before comparing parts.

Check packaging damage, attachment movement and changes to shaft or housing alignment.

Inspect the mating slot or hook feature, actual engagement, load direction and motion history.

Use identified springs across identified assemblies so the comparison can distinguish part effects from housing effects.

Compare bend locations, exit angles and cumulative guide resistance with the original path.
