rpm PTO to the spline shaft of the vacuum pump.
Do not exceed the maximum allowed angle of the PTO coupling
- version with pulley (…AP) it is necessary to insert an idle pulley sheave on the
drive shaft of the vacuum pump and fasten it by means of specific screw located in
the front area of the shaft. The idle pulley can be directly mounted on the keyed
shaft. Mount this sheave as near as possible to the bearing. Never transmit axial
loads. Connect the two pulleys - the idle pulley to the drive pulley - by means of
drive belts of suitable length. The number and type of belts used should be
specified by the sheave manufacturer. At the end of this operation, it is necessary
to install a belt guard (covering all belts and pulley sheaves) required to protect all
operators.
- - version with direct drive (…AD) it is necessary to connect the shaft of the PTO,
gas/diesel drive or 1000 rpm electric motor to the drive shaft of the vacuum
pump.
Do not exceed the maximum allowed angle of the drive shaft.
-hydraulic version (…AH) it is necessary to fit a hydraulic motor (SAE B 4 bolt for
AIR series) and Moro hydraulic drive bracket and coupling to the pump.
4. Connect the rubber suction and discharge hoses from the tank to the vacuum pump
fastening it to the hose barb fittings provided by means of a properly sized metal clamp.
3.3 REMOVAL
The vacuum pump must be removed following this procedure:
1) stop the power takeoff.
2) remove the connections to the power takeoff and remove hydraulic connection (if any).
3) remove the hosing that connects the vacuum pump to the tank.
4) remove the mounting screws and remove the vacuum pump.
3.4 DISASSEMBLY
3.4.1 Disassembly of the driven side section
