Where it is found that a nut of the elastic stud can be turned considerably less than
the others, it must be assumed that the respective studs has become insufficiently
tensioned.
Possible causes:
− Sealing rings, i.e. back-up and O-rings defective.
− Piston of pre-tensioning jack jams.
− Junctions of HP hoses leaky.
D To remedy the cause, loosen all studs and then repeat the tensioning proce-
dure according to 9403−4.
⇒ Release pressure to zero and remove all pre-tensioning jacks.
Verify again that all nuts have been turned one time equally by an angle of approx.
520_.
For loosening the elastic studs, screw back the round nuts by about 1 turn.
