ASSEMBLY
1. Always press on the inner ring of a ball–type bearing
when installing the bearing on a shaft.
2. Always press on the outer ring of a ball–type bearing
when pressing the bearing into a bearing recess.
3. Whenever grasping a tool or part in a vise, always use
leather–covered or copper–covered vise jaws. Take
extra care not to damage threads or distort housings.
4. Except for bearings, always clean every part and wipe
every part with a thin film of oil before installation.
5. Check every bearing for roughness. If an open bearing
must be cleaned, wash it thoroughly in clean solvent
