SHOCK STRUT SHIMMY DAMPER
The shimmy damper has a reservoir of fluid carried in the
piston 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 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.
