Two way hydraulic rear pump
The two way hydraulic gear pump is not
pre-defined as rotating right or left. The
pump can be operated with right-hand
rotation (clockwise) or left-hand rotation
(counterclockwise) as desired. However,
you should keep operating it in the direc-
tion preferred initially. Otherwise the
volumetric efficiency of the pump will de-
crease and its service life will become
shorter.
4.9.2. Pump – PTO Connection
The pump should turn RIGHT (clock-
wise) if the main transmission turns
RIGHT and the auxiliary transmission is
connected.

4.9.2.1. Hydraulic Oil
Hydraulic Oil Operating Temperature
The minimum operating temperature is
-23°C while the maximum operating tem-
perature is 82° C. The ideal operating
temperature for the oil in the system is
35°C to 55°C.
•
Mineral based hydraulic oil should
be used in the system.
•
The viscosity of the hydraulic oil in
the system should be 12 to 100 cSt
(mm²/s). The ideal viscosity is 20 to
40 cSt.
•
Low viscosity hydraulic oil should be
preferred in cold weather and high
viscosity hydraulic oil should be pre-
ferred in hot weather.
Filtering
•
The system must be equipped with
an oil and an air filter. The oil filter
should not be used on the pump
suction line but on the tank return or
pressure line.
•
The most efficient filtering is 10 µm.
Filtering up to 25 µm is allowed.
