2 Wheel Drive Operation
When the switch is in the 2 wheel drive position,
solenoid valve A is energised. The energised
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.
