11.7 Longitudinal motion pushrod bearings
During repairs, never pull pushrods out of longitudinal motion bearings,
because all balls will leave their cages. Consequently, for re-installation
near each bearing an opening must be cut and repaired afterwards.
These bearings are being used throughout the wing control systems, in the
fuselage for elevator and aileron control systems.
Caution: Longitudinal motion pushrod bearings should never be greased or
oiled, their plastic balls and bearing surfaces will soon be destroyed due to
collection of small foreign matter !
