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.

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).

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 .

tighten the nut. Make sure that the
edge of the hole has no
deformation.
