Before each
assembly
Water insoluble bearing
grease or grease
containing molybdenum,
for instance:
Molykote BR2
(Temperature range from
-30° to130° C
<-22° F to 266° F> )
Landing gear: all joints
(also at forward rubber
bearings)
Once a year Oil
Note: protect rubber parts
against oil.
Bearings at control surfaces After
disassembly
only
Molykote grease BR2 (-
30° C to 130°C <-22° F
to 266° F >)
or Molykote grease 33 (-
70° C to 180°C<-94° F to
356° F>)
Caution: Never grease longitudinal motion pushrod bearings. They will soon be
destroyed due collection of foreign matter. These bearings are used in elevator
system, aileron system, air brake system and landing gear drive.
Caution: The friction dampers inside the air brake boxes prevent oscillations
during extension of air brakes. Therefore, friction pads should never be greased or
oiled !
