Section 8
Handling, Serv & Maint
7. The shock strut piston must be clean. Remove foreign
material from the exposed piston with a soft cloth moist-
ened with hydraulic fluid.
If a compressed air bottle containing air
under extremely high pressure is used,
exercise care to avoid over-inflating the
shock strut.
NEVER FILL SHOCK STRUTS WITH
OXYGEN.
SHIMMY DAMPER
The shimmy damper has a reservoir of fluid carried in the pis-
ton rod. Two coil springs installed in the piston rod keep fluid in
the shimmy damper under pressure. As fluid is lost through
leakage it is automatically replenished from the reservoir until
the reservoir supply is exhausted.
To check the fluid in the shimmy damper, insert a wire approx-
imately 1/32 inch in diameter through the hole in the disc at the
aft end of the piston rod until it touches the bottom of the hole
in the floating piston. Mark the wire, remove it, and measure
the depth of the insertion. When the shimmy damper is full,
insertion depth is 2-3/16 inches; when empty, 3-1/16 inches.
