The grooved ball bearings are to be cleaned and greased during every main inspection,
and tested for flexibility of motion and bearing play. If motion of bearings is slow,
determine the reasons (e.g. misalignment, bent component part, locked up stress,
etc.). Damaged grooved ball bearings are to be exchanged. The space of the ball
bearings needs to be filled completely with
grease TOP 2000 of AGIP Schmiertechnik
