11.4 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-, aileron- and landing gear drive 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 !
