PUMP INSTALLATION

9.1

Installation

The pump must be fixed horizontally using the M16 threaded
support feet. Tighten the screws with a torque of 200 Nm.
The base must be perfectly flat and rigid enough as not to
allow bending or misalignment on the pump coupling axis/
transmission due to torque transmitted during operation.
Two lifting brackets are mounted on the pump for easy
installation, as per the figure below.
The brackets are sized for lifting the pump only.
Therefore they must never be used for any
additional loads.
Replace the oil filling hole closing service plug
(red) positioned on the rear casing cover. Check
the correct quantity with the oil dipstick.
The oil dipstick must always be reachable, even
when the unit is assembled.
The pump shaft (PTO) should not be rigidly
connected to the propulsion unit.
The following types of transmission are
recommended:
- Flexible joint.
- Cardan-shaft (comply with manufacturer's Max.
recommended working angles).
- Belts, for proper application consult with our
Technical or Customer Service Departments.

Changing version and reduction unit
positioning
The version can only be modified by trained and
authorised personnel and carefully following the
instructions below:
1. Separate the hydraulic part from the mechanical
part as indicated in chapter 2 in par. 2.2.1 and
2.2.3 of the Repair manual.
2. Turn the mechanical part 180° and reposition
the rear casing cover in such a way that the
oil dipstick is turned upward. Reposition the
lifting brackets and relative hole closing plugs
in the upper part of the casing. Reverse the two
inspection covers making sure that the open
one is positioned at the bottom. Finally, properly
reposition the specification label in its housing
on the casing.
Make sure the drainage hole of the bottom
inspection cover is kept open.
3. Unite the hydraulic part to the mechanical part
as indicated in chapter 2 in par. 2.2.2 and 2.2.4 of
the Repair manual.
The position of the reduction unit can only be
changed by authorized specialized personnel
meticulously following the instructions in the
Repair manual.
