1. General
We recommend that you do a check of the tension of all tie rods one year after
commissioning, refer to 0380 − 1 Maintenance Schedule, Tie rod . If necessary, apply
tension to the specified value. Random checks can be done during overhauls.
2. Tension Check
1) Remove the protection cover (1, Fig. 1 )
from all tie rods (2).
2) Clean the surfaces of the intermediate
ring (4).
Note: Start with the tie rods (a − a) in the
middle of the engine, then b − b,
etc).
3) Attach the two pre-tensioners (94180)
to two tie rods (2, a − a Fig. 1 ).
4) Apply a tension of 1500 bar to the tie
rods (2), refer to 9403 − 4 .
5) If possible, tighten the round nuts (3).
6) If the round nut (3) cannot move, do
step a ) to step b ):
a) Put a round bar (94005) through
the opening of the jack and into a
hole in the round nut .
b) Use a hammer to loosen, then
tighten the nut. Make sure that the
edge of the hole has no
deformation.
7) Remove the pre-tensioners (94180),
refer to 9304 − 1.
8) Apply a layer of Molykote paste G to
the threads of the tie rod (2) to prevent
corrosion.
9) Install the protection cover (1).
10) Do step
3 ) to step 9 ) for the remaining
tie rods.
