SHOCK STRUT SHIMMY DAMPER
Section VIII
Handling, Serv - Maint
The shimmy damper has a reservoir of fluid carried in the
piston rod. Two coil springs installed in the piston rod keep
the fluid in 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 level in the shimmy damper, insert
a wire,
approximately 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.
NOTE
The measuring wire should be inserted in the
hole in the floating piston rather than against the
piston face to give a more accurate reading. To
determine if the wire is inserted in the hole in the
floating piston, insert the wire several times,
noting insertion depth each time. When the wire
is inserted in the hole, the depth will be about
1/4
inch greater than when it rests against the piston
face.
When the shimmy damper is found empty or nearly empty, it
should be refilled. See Shop Manual.
