ASSEMBLY
Always press on the inner ring of a ball–type bearing
when installing the bearing on a shaft.
Always press on the outer ring of a ball–type bearing
when pressing the bearing into a bearing recess.
Whenever grasping a tool or part in a vise, always use
leather–covered or copper–covered vise jaws. Take
extra care with threaded parts or housings.
Always clean every part and wipe every part with a
thin film of oil before installation.
Apply a film of O–ring lubricant to all O–rings before
final assembly.
Check every bearing for roughness. If an open bear-
ing must be cleaned, wash it thoroughly in a suitable
cleaning solution and dry with a clean cloth. Sealed
or shielded bearing should never be cleaned. Work
grease thoroughly into every open bearing before
installation.
