3.7 - RE-ASSEMBLY - REINSTALLATION

IMPORTANT: Before proceeding with any re-fitting, replace the gaskets of the opened parts.

3.7.1 - REFITTING OF FRONT PART

1) Remove the seeger ring;
2) Remove the bearing;
3) Replace the seal on the flange;
4) Insert the pins supplied into the body;
5) Install the front flange onto the body using screws tightened
to 45 ÷ 55 Nm;
7) Refit the front cover back onto the flange;
8) Remove the centring pins from the body.
4 - ROTATION DIRECTION REVERSAL – ROTARY BLADES VACUUM
PUMP WITH FORCED OR AUTOMATIC LUBRICATION
If it is necessary to reverse the direction of rotation of a rotary blades vacuum pump with automatic lubrication, proceed as follows:
- remove the back cover and the right or left automatic lubrication pump
(together with the connection joint) from the flange;
- remove the screws from the back flange;
- use two screws in the threaded extraction holes until the flange is removed;
- remove the screws from the front flange;
- extract the rotor from the body together with the front flange;
- rotate the body together with the manifold 180° on a horizontal level;
- replace two flange gaskets;
- slide the rotor in the body together with the front flange;
- tighten the six securing screws of the front flange to the body;
- disassemble the bearing and the seeger from the back flange;
- approach the back flange to the pump body, positioning it on a level with the securing holes;
- insert the six securing screws in the holes and tighten;
- assemble the bearing on the flange by means of a stopper and fit the seeger;
- re-assemble the back cover and replace the automatic lubrication pump DX or SX with another one with opposite direction of
rotation (together with the coupling joint) to the flange.
In the case of a Ballast rotary blades vacuum pump with forced lubrication follow the same instructions as
specified above but the lubrication pump must not be replaced as it is bi-directional.
