Coupling Bearing Inspection
  Since the coupling bearing is made to extremely close
tolerances, the clearance can not normally be measured.
                              NOTE
    ○It is not necessary to remove the coupling bearing for
      inspection. If the bearing is removed, it will need to be
      replaced with a new one.

• Turn the bearing in the coupling back and forth [A] while
  checking for plays, roughness or binding.
    If the bearing play, roughness or binding is found, replace
    the bearing.
•   Examine the bearing seal [B] for tears or leakage.
    If the seal is torn or is leaking, replace the bearing.
Coupling Bearing Lubrication
                              NOTE
    ○Since the coupling bearing is packed with grease and
      sealed, lubrication is not required.
