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:
- measure the length of free stretch (t)
- In the middle of free stretch of the belt (t) apply a force(perpendicular to free stretch) nought to bend the belt 1.6 mm per 100 mm
in lenght of the free. For example, the decline of a free stretch of 1000 mm is 16 mm.
- Compare the force you have applied and measured through a instrument with datas stated under our table. If the force is included
between "minimum force" datas, it means that the belt is not enough streched.
If the force exceeds "max force" datas, it means that the belt is too stretched.
3-D) To install the .../D version Rotary blades vacuum pump, connect the cardan shaft at 1000 rpm of the tractor to the P.T.O. shaft
of the Rotary blades vacuum pump.
Don't exceed the maximum slope allowed for the cardan shaft.
3-H) To install the .../H version Rotary blades vacuum pump, attach an hydraulic motor (flanging European unification - Group 3,5
for MEC 2000-3000-4000-5000-6500-8000 series and Group 4 for STAR, MEC 9000-11000-13500 and MEC 16500 series) to the
power take-off shaft and fix it, using special screws, to the cast iron support located at the front.

HYDRAULIC DRAFT (/H version)
The hydraulic system required for the operation of Rotary blades vacuum pump .../H is schematized in Figure 3 and the technical
characteristics of the hydraulic motor are shown in Table 2.
The splining of the hydraulic motor is of a type DIN 5482 - Z=23 for MEC 9000-11000-13500, STAR and MEC16500 series and of
type DIN 5482 - Z=20 for MEC 2000-3000-4000-5000-6500-8000 series.
