Brush surfaces as
necessary with dry
cleaning solvent (item 74,
App F). Alternate
procedure: brush on dry
cleaning solvent (item 74,
App F) to loosen stubborn
soil. Apply cleaning
compound (item 44,
App F), then brush and
rinse. Note: corrosion
preventive compound
(item 61, App F) may be
applied to provide a clear
protective film.
CAUTION
Wipe away from seal areas to prevent collection of soil at seal junction areas. Ensure piston surface
is clean and completely lubricated but not dripping. If piston is dry, telescoping action of strut will
force gritty particles into cylinder, causing leaks and eventual failure. Do not use aerosol dispensed
fluid on hydraulic systems.
NOTE
Crash attenuation features of the landing gear shock struts (lower exposed piston areas) should be
wiped clean with corrosion preventive compound (item 63, App F) then lightly coated with corrosion
preventive compound (item 62, App F).
