It is recommended to check the tightness of the bearing housing during this
phase. Attach a piece of hose turned upwards to the OUT connector (figure
23) to prevent overflow. Fill the bearing housing by adding recommended oil
through the IN connector (figure 23). Rotate the shaft in different directions
several times in order to expose the possible leak points in the mechanical seal
(figure 24, point B) Also check that the shaft seal that rubs against the surface
of the drive flange is not leaking (figure 24, point A).

Place the key (figure22, point C) in the keyway (figure 22, point D).
Press the drive flange against the cone at the end of the shaft.
The shaft seal in the drive flange contacts the key, but if you lift
the rear edge of the drive flange slightly, it will clear the key. The
tightening torque of the drive flange nut (figure 22, point A) is 150
Nm. Use a thread locking compound (such as Loctite 242).
