LR3/Disco 3
The rotational movement of the motor shaft turns the shifting cam (3) to high range position. The shifting cam then moves
the shifting sleeve (1), via the high/low shifting fork (2), into the high range position. After the synchronisation sequence,
the planetary ring gear is connected to the high range dogteeth, via the shifting sleeve, on the differential carrier. In this
position, the input speed equals the output speed, which equates to a high range ratio of 1:1.
