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
The outer circuit supplies pressurized oil to hydraulic
implements connected to the outer outlets of the hydraulic
system terminated with quick-couplers.
The sockets of the rear (A) as well as front (B) quick-
couplers have the inner diameter of 12.5 mm and comply
with the international ISO 5675 standard.
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.
