MANUAL
SHIMMY
DAMPER
To
check
the fluid
level
in
the
shimmy damper,
insert
a
wire
of
approximately
1/16-inch
diameter
through
the hole
in the disc
at
the
end
of the
piston
rod until it
touches
the
bottom of
the hole
in
the
floating
piston.
Mark
the
wire,
remove
and
measure
the
depth
of
insertion.
Inserting
the
wire
in
the hole
of
the
floating
piston,
rather
than
letting
it
hit
against
the
face
of
the
piston,
will
give
a
more
accurate
check.
NOTE:
To
determine
if
the
wire is inserted in the hole
of
the
floating
piston,
insert
the
wire
several
times,
noting
each
insertion
depth.
When the
wire is
correctly
inserted the
length
will be
approximately
1/4
inch
greater.
When the
shimmy
damper
is
full,
the
inserted
depth
is
2
3/16 inches. The
empty
reading
is
3
1/16
inches. To
add
hydraulic
fluid
(13,
Chart
3),
remove
the
shimmy
damper
and
proceed
as
follows:
a.
Remove the
cotter
pin,
washer
and
spring
from
the
piston
rod.
b.
Remove the
internal
snap
ring,
scraper
ring
and
the
end
seal from
the
aft
end
of
the
barrel.
(Opposite
the clevis
end.)
c.
Insert
a
6/32-threaded
rod
into
the
floating
piston
and
remove
the
piston,
using
extreme
care
when
moving
the
O-ring
seal
of
the
floating
piston
past
the
drilled
holes
in
the
piston
rod.
I
d.
Push
the
piston
rod
to
the
clevis
end
and
fill
the
barrel
with
hydraulic
fluid
(13,
Chart
3).
e.
Slowly
actuate
the
piston
rod,
allowing
the
fluid
to
flow
into
the
clevis-end
chamber,
then
return
the
piston
to
the
clevis
end of
the
barrel.
f. Refill
the
displaced
fluid
and
replace
the end
seal,
scraper
ring
and
internal
snap
ring.
g.
Fill the
piston
rod with
fluid.
h.
Reinstall
the
floating
piston,
spring,
washer
and
cotter
pin.
Spread
the
cotter
pin
to
allow
clearance
for
the
measuring
wire.
