REpLACEMENT OF THE ELASTIC ELEMENT
BLADE 15 ÷ 22 has been designed in a way that makes
it possible to replace the elastic element without having
to dismantle the rotor-stator unit. Before starting, make
sure the compressor is correctly isolated from the
electrical supply. Remove the three protective covers
from the coupling assembly.
Loosen the motor hub fixing screws. Slid the motor hub
and the elastic element to the right along the motor
shaft close to the motor flange.
With an extended hexagon key remove the fixing screws
from the compressor hub taking advantage of the gap
created by the sliding.
Remove the two halves through the holes in the
coupling assembly and replace the old elastic element.
In this phase it is also possible to easily replace the oil
seal. First, remove the rotor shaft key (Pict. 4 - pos. 1) and
the seal housing flange (Pict. 4 - pos. 2).

Once the oil seal has been replaced in the flange, rebuild
the part using the given tool (Pict. 5 - pos. 3).

Rebuild the compressor hub (and the new elastic
element) with the given tool by maintaining an axial
positioning.
Therefore, tighten the fixing screws with the torque
wrench (120 Nm couple). Make the elastic element and
motor hub flow towards the compressor, until it meets
the other edge of the given tool.
Tighten the fixing screws as explained above. Remove
the tool from the elastic coupling.
