1.1 SYSTEM DESCRIPTION, PNEUMATICALLY ASSISTED GEARBOX
CONTROL (SERVOSHIFT)
The “Servoshift” pneumatically assisted gearbox
control is an assisted mechanical/pneumatic
gear selector system for the gearbox.
This system is identical to the mechanical
gearbox controls, from the gear lever to the
gearbox, however, the gearbox is pneumatically
assisted.
For details of adjustments to the selector
mechanism, refer to “Mechanical gearbox
control”.
The Servoshift unit is an important feature of
the pneumatically assisted gearbox control.
The Servoshift unit can be ventilated in two
ways:
1. Ventilation via the neutral position
valve (4):
1. Servoshift unit
2. Selector rod
3. Selector shaft housing
4. Neutral position valve
