OPERATION
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 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.
The differential lock, when applied, prevents all
available power being transmitted to the road wheels
offering least resistance and is especially useful for
’off-road’ conditions. When selected, the selector
fork engages the dog clutch on the differential shaft
with a gear on the front output shaft; this locks the
differential and provides fixed drive thereby
transmitting equal power to both output shafts.
