1.4 Checking the straight ahead driving position of the steering gear and the vehicle
Attention:
Steering gears equipped with an automatically adjusting hydraulic steering limitation must not be
rotated to the end positions if the steering linkage had been removed previously.
Vehicles with single-wheel suspension:
Place the wheels of the steered axle on swivel plates.
Vehicles with a rigid axle:
Jack the steered axle up. ¡
Move the steering gear to mid-position by rotating it half the total number of steering wheel
turns. Then rotate it further until the marks (see Fig. 25) coincide.
Now turn the steered wheels to the straight ahead driving position.
Corrections can be made by screwing the ball joint on the drag link further in or out.
Attention:
If the steering wheel position is not correct or if a length correction of the steering linkage turns
out to be necessary, it may well be that this necessity originates in a preceding accident-like event.
We, therefore, recommend to check whether the serration of the sector shaft (30) is twisted (to
do so, pull the drop arm off), whether the input shaft is installed in a twisted position and whether
some or all further transmission elements are bent or have cracks. In addition, check the play as
detailed in Chapter III., para. 3. Deformed components may not be re-bent to shape but must be
replaced.
Additionally, for versions with automatically adjusting hydraulic steering limitation:
If required, fit new screws (20 and 128, respectively) and reset the steering limitation - see Chapter
III., para. 5.
