Hydraulic system
The system consists of the inner and outer circuit.
The source of pressurized oil is a gear pump.
Oil is drawn from the common filling of the gearbox and final drive housing.
Hydraulic pump
The hydraulic pump cannot be disengaged. When the
engine is running, the pump is in operation.
Pump type
Delivered quantity
URD 25/10.90V
69 l/min
The pressure generated in the hydraulic system by the
hydraulic pump is limited by a relief valve to 20 MPa.
Control elements placement
Control panel is placed on the right rear mudguard.
1. Electrohydraulics control
2. External hydraulic circuit control
Outer hydraulic circuit
It delivers pressure oil for hydraulic appliances connected to the hydraulic outlets terminated by quick
couplings. Both the rear and front drawer sockets are 12.5 mm in headroom and are international ISO
standard 5675 compliant.
Connecting and disconnecting quick-couplers
When connecting and disconnecting the quick-couplers pay increased attention with regard to
the residual oil that remains in the socket or on the plug of the quick-coupler. For environmental
reasons after every disconnection of quick-couplers this residual oil must be removed with any
textile material.
Quick-couplings with drip collection
On request, dripping system for holding leakage oil can be
installed. Regularly check whether the tank is not full;
dispose of the oil in an environment-friendly way.
