# Mechanisms: references

129 records: 3 read sources that the rules and checks may cite, and 126 records catalogued from the Reference Map, not yet read. Joints, linkages, motor mounts and the motion between parts.

Catalogued records are search snippets: their numbers are the authors' claims and their licences are as the map states them, unread. Cite one only after reading it.

The same records as JSON: https://cad-agent.valpatel.com/catalog/references/mechanisms.json. All areas: [references](../references.md).

## Coverage

What cad-agent checked when the map was made; each drafted issue was never posted.

- **ISO 286 fits (H7/g6) and bearing seats** (Missing): ISO 286 IT grades and hole/shaft deviations, preferred fits (H7/g6, H7/p6), bearing shaft/housing fits, machined-fit clearance windows absent. Drafted issue, never posted: "Add ISO 286 fit calculator and bearing seat fits".
