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 screw (1, Fig. 1 ) and the
protection cover (2) from all tie rods (3).
2) Clean the surfaces of the intermediate
rings (4).
Note: Start with the tie rods (a − a) in the
middle of the engine, then b − b,
etc).
3) Connect the applicable equipment to the
double pre-tensioning jacks as shown in
9403 − 2 .
4) Attach the two double pre-tensioner
jacks (94180) to four tie rods (3, a − a),
refer to 9403 − 4 .
5) Apply a pressure of 1500 bar
6) If possible, tighten the round nuts (4)
with the rod (94005 − 6).
7) If the round nut (3) cannot move, do
step a ) to step b ):
a) Put a rod (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.
8) Apply a layer of Molykote paste G to
the threads of the tie rod (2) to prevent
