Quick answer: Include spring envelope, shaft position, flange spacing and housing location relative to a common datum.
Which dimensions should be combined in a clearance review?
Checking each component's tolerance independently does not prove assembly clearance. A small shaft offset and a narrow flange gap may combine in the same direction. Identify the worst credible stack rather than selecting nominal values. Also distinguish radial clearance from the axial room needed for smooth strip tracking.
A practical verification method
Build or simulate the worst stack and confirm motion without edge scuffing throughout the working stroke.
| 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 | Build or simulate the worst stack and confirm motion without edge scuffing throughout the working stroke. | 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.
