VERTICAL STABILIZER REMOVAL/INSTALLATION – continued
j. If removed, install two grounding jumpers
(14.1) on two terminal studs (14.2).
(1) Install two washers (14.5) and jumpers (14.1)
on terminal studs (14.2).
(2) Install two nuts (14.3) and washers (14.4) on
two terminal studs (14.2).
k. Perform electrical bond check on jumpers
(14.1) and nuts (14.3) (TM 55-1500-323-24).
(1) Bond shall be 0.1 OHM or less. Use
ohmmeter.
l. Seal jumpers (14.1) and nuts (14.3). Use
sealing compound (item 176, App F).
NOTE
On aircraft modified with elastomeric
mounts the two vertical stabilizer hy-
draulic line assemblies are installed
with the 45 and 90 elbows at the
back of the vertical stabilizer hard
lines.
On aircraft modified with elastomeric
mounts ensure that the quick discon-
nect fittings are attached to the straight
end of the hoses.
On aircraft that have not been modi-
fied with elastomeric mounts the two
vertical stabilizer hydraulic line assem-
blies are installed with the 45 and 90
elbows at the bracket on the F.S. 547
frame.
m. Install two couplings (13) on (14).
(1) Turn couplings (13) clockwise until locking
teeth engage fully on coupling halves (14).
n. Install two couplings (11) on (12).
(1) Turn couplings (11) clockwise until locking
teeth engage fully on coupling halves (12).
