1.2 TIGHTENING TORQUES
The tightening torques stated in this paragraph
are different from the standard tightening
torques stated in the overview of the standard
tightening torques. The other threaded
connections which are not stated must therefore
be tightened to the tightening torque stated in
the overview of standard tightening torques.
When attachment bolts and nuts are to be
replaced, it is important - unless stated
otherwise - that these bolts and nuts are of
exactly the same length and property class as
the removed ones.

Steering wheel attachment bolt 50 ᐔ5Nm
Universal joint
Universal joint attachment bolt 56 ᐔ5.6 Nm(1)
Airbag
Airbag module attachment bolt 5 ᐔ1Nm
Contact unit attachment bolt 1.2 Nm
Electronic unit 10 ᐔ2Nm
Note:
(1) Always replace the attachment bolt and

2. CAB SUSPENSION
2.1 GENERAL
The day cab can be fitted with rubber spring
elements at the front. The version with rubber
spring elements at the front does not have a
stabiliser.
The coil spring elements are fitted with shock
absorbers.
The length of the spring elements and the cab
height cannot be adjusted.
On models equipped with coil spring elements at
the front, a difference in cab height can be
corrected to a certain extent using the stabiliser
bar.
At the rear, coil springs are used. The length of
the spring elements varies depending on
whether a day cab or a sleeper cab is involved.
Cab support, general
The distance between the cab
supports (A) measured from the
left side of the left support to the
left side of the right support is: 1000 mm
