DESCRIPTION AND OPERATION

41-19

Power flow - transfer box in HIGH ratio

Up to 03 Model Year section shown, from 03MY similar

The gearbox output shaft transmits power to the mainshaft input gear which is in constant mesh with one of the
intermediate gears. The intermediate gears are in constant mesh with the high and low range output gears running
on the differential rear shaft.

Power is transmitted to the output shafts via the differential assembly by locking either the high or low range gears to
the differential rear shaft. This is achieved by means of the high/low selector fork, sleeve and splined hub.
