2 Wheel Drive Operation (See Figure 7-11)
When the switch is in the 2-wheel drive position, solenoid
valve A is energized. The energized solenoid A1 causes the
valve spool to move and form a connection between ports 3
and 2.
Pressurised oil is directed to piston C via ports 3 and 2. The
piston moves actuating sleeve F and then pressure plate G
against the force of springs D, thus releasing the spring force
on the clutch friction/counter plates of clutch pack B.
Because there is no spring force, the friction/counter plates
of clutch pack B now freely rotate on the output shaft, thus
disengaging drive to the front axle.
