5.2 TIGHTENING TORQUES
The tightening torques stated in this section are
different from the standard tightening torques
included in the overview of standard tightening
torques. Any other threaded connections that
are not specified 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 ones removed
.

Toe
Toe values are shown in the graph.
Note:
In the graph, the toe has a value of
0.5
ᐔ 1 mm/m toe-in at 75% of the permissible
loading weight. The axle load consists of the
unloaded axle weight + loading weight.
Explanation of graph
1.
At the top of the graph, the axle type and
the axle configuration (1) is shown.
2.
The toe is shown in mm/m on the left-hand
side of the graph. The values above the 0
line show toe-in values, indicated by the
symbol (2).
The values below the 0 line show toe-out
values, indicated by the symbol (3). The
toe-out values are shown as negative
values.
3.
The axle load (4) is shown at the bottom of
the graph.
4.
The permitted toe at any axle load is
indicated by the shaded area (5) in the
graph.
5.
If the measured value lies outside the
shaded area, the toe must be adjusted to
the value indicated by the continuous
line (6).
