g) Insert and partially tighten the screws that lock the disks to the
flywheel. Keeping the fan still (ECP28), turn the flywheel until another
two holes are in the same position and partially tighten the screw.
Repeat this operation for all the other holes
h) after inspecting the correct centring of the disks on the engine
flywheel, the screws must be completely tightened
i) (For series 28) once the clamping of the disks is over, stop the fan
once again by tightening the screw with a torque wrench setting
adjusted at 20 Nm ± 10%; the radial position of the fan is not binding
for the correct operation of the system
l) fix the protection grids supplied with the generator.
Compliance with items "i" and "l" is of the utmost consequence in order
to avoid serious damages to the generator or hazardous situations for
people or objects.
Only after a correct mechanical coupling, proceed with the electrical
connections
