Constant Torque Spring Rotation Margin for Assembly Adjustment

Quick answer: Include the actual setting operation and tolerance correction in the required rotation window, using an approved margin rather than an arbitrary extra turn.

How much adjustment travel should be included in a specification?

Assembly tuning can consume travel that the design assumed was reserved for use. Document the setting position and final reference state. The same spring must satisfy both production adjustment and product operation without exceeding its approved transfer range.

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.
