1.2 SYSTEM DESCRIPTION

The gearbox consists of a main gearbox with four

synchromesh forward gears, a non-synchromesh

crawler gear, and one non-synchromesh reverse

gear. Between the main gearbox and the output

shaft there is a set of planetary range gears with

pneumatic synchronisation.

In the low range (planetary system engaged), the

crawler gear and gears 1, 2, 3 and 4 can be

engaged.

In the high range (planetary system disengaged),

gears 5, 6, 7 and 8 can be engaged.

The switching system is in a "single-H" pattern.

Use of the "single-H" system means that the low

or high range must be selected by means of a

button on the ball of the gear lever prior to

engaging gear. The group is changed as soon as

the selector shaft passes through the neutral

position.
