3 - ASSEMBLY, MOUNTING, INSTALLATION, DISMANTLING,
When carrying out maintenance operations, inspections, checks or repairs it is advisable to wear the individual
protective devices listed in this manual.
In the case of pump painting do not paint the identification plate, taps, oil sight glass, the oil level dipstick or the
vent plugs.
All maintenance operations, inspections, checks and repairs should be carried out with the greatest care and with
the tractor not running and the power take-off disconnected.
It is essential to prevent sewage from entering the Rotary blades vacuum pumps.
The entrance of sewage would cause the blades and consequently the rotor to break.
It is therefore necessary to equip the system with an overflow valve, "3", and a safety overflow valve, "2", between
the rotary blades vacuum pump and the tank car (see Figure 3).

3.2 - ASSEMBLY AND FITTING - INSTALLATION

The Rotary blades vacuum pump should be assembled and installed using the following procedure:
1) Assemble the Rotary blades vacuum pump horizontally with its feet facing downwards. The assembly position on the vehicle
should be easy to access and be protected. A 5° maximum longitudinal slope of the pump with respect to the horizontal plane must
not be exceeded.
2) Bolt the Rotary blades vacuum pump using screws and nuts passing through the specially provided slots or holes in the feet;
3-P) To install the .../P version Rotary blades vacuum pump, attach a driven pulley to the shaft and fix it with the special screw
located on the front of the shaft. The driven pulley may be fitted directly on the cylindrical shaft if the radial load is brought close to
the bearing. Never transfer axial loads. Then connect the driven pulley to the driving pulley with the correct length of driving belts.
The number and type of belts must be calculated according to the power to be transferred to the rotary blades vacuum pump. When
this operation has been completed, the necessary guard must be installed to isolate the driving parts (pulleys and belts) and prevent
access to them by the operators.
- The best tension is the lower one where the belt doesn't slide under max loading condition
- Check frequently the tension during first 24/48 hours of running phase
- The over-tension reduces the life of belt and bearing
- Keep belts free from any material which may cause sliding
- Check periodically the transmission. Set it when sliding
To check the tension on a normal transmission, do what follows:
