- one-way vacuum valve ( 2 ) – is placed on the connection hose between the inlet
manifold and the electric valves.
-“ 4x4 ” coupling control wiring – is performing the connection of the system
components to the vehicle electrical equipment.
The system is working based on the vacuum from the inlet manifold (1), which, during
engine running, is acting on the membrane separating the two vacuum capsule compartments
(12). This will impose the longitudinal movement of the capsule axle, which by means of
the control lever (6) will act upon the front transmission coupling control axle (7), placed
in the gearbox right front part (1) . In this way is performed the front transmission coupling
and the transit from rear drive to all wheel drive (4 x 4).
