leather–covered or copper–covered vise jaws to
protect the surface of the part and help prevent
distortion. This is particularly true of threaded
members and housings.
2. Always press on the inner ring of a ball–type bearing
when installing the bearing on a shaft.
3. Always press on the outer ring of a ball–type bearing
when pressing the bearing into a recess.
4. Except for bearings and mechanism parts, always
clean and wipe every part with a thin film of oil
before installation.
5. Wipe a thin film of mechanism fluid on all internal
mechanism components before installing them in the
mechanism.
6. Apply a film of o–ring lubricant to every o–ring
before installation.
