HYDRAULIC SYSTEM

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.

Location Of Control Elements

- EHR - B - BOSCH ELECTROHYDRAULIC SYSTEM

The control panel (1) is located on the right fender.

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 quickcouplers this residual oil must be removed with any textile material.

*QUICK-COUPLINGS WITH DRIP COLLECTION

Optionally, a system of collection of residual oil drips with a tank can be installed.

Regularly check whether the tank is not full; dispose of the oil in an environmentfriendly way.

Oil Quantity Drawn From The Outer Hydraulic Outlets

For the maximum possible quantities of drawn oil see the following table. In case of higher consumption the transmission oil level may drop in such a way that the transmission and hydraulic pumps may aspirate air and there is a danger of damaging the pumps, mainly the transmission pump, as well as the torque multiplier or the PTO clutch.
