7.3 FRONT TRANSMISSION UNIT (Park 4WD only)
7.3.1 General description
The front axle consists of a monobloc unit, which includes the hydraulic drive motor and the dif-
ferential.
The unit is operated by two hydraulic pipes connected to the rear unit and the synchronism of the
speeds is ensured by a dynamic balancing valve for the correct balancing of the circuit.
The removal of the transmission unit from the machine is only required in case of replacement or
revision by a Manufacturer's Service Centre.
The operating diagrams and management methods of the hydraulic circuit are described in chap-
ter “HYDRAULIC SYSTEM”, [ 8] .
