16

Move steering to straight-ahead position

 The elevation on the 1st steering idler arm (9) must be horizontal so that the drag link (1) can be detached from the 1st steering idler arm (9).
The wheels of the 1st front axle do not have to be in the straight-ahead position. When the drag link (2) detached, it is possible to turn the wheels of the 1st front axle.

17

Unscrew nut (8) and detach drag link (1) from 1st steering idler arm (9)

18.1

Turn steering completely to left

On left-hand drive vehicles

 When doing so, have the drag link (1) held by a second person. Make sure that the drag link (1) does not tilt when the steering is turned.
The wheels of the 2nd front axle are also steered by the pressure in the steering cylinder.

18.2

Turn steering completely to right

On right-hand drive vehicles

 When doing so, have the drag link (1) held by a second person. Make sure that the drag link (1) does not tilt when the steering is turned.
The wheels of the 2nd front axle are also steered by the pressure in the steering cylinder.

19

Unscrew nut (5) and remove drag link (1)

 To remove the control rod (1), turn the steering to the right (with left-hand drive vehicles) or to the left (with right-hand drive vehicles) if necessary.

22.1

Turn wheels of 2nd front axle to left by hand directly at axle until drag link (1) can be attached to 1st steering idler arm (9)

On left-hand drive vehicles

 It is not advisable to turn the wheels on the 2nd front axle using the steering wheel because the pressure always causes the steering cylinder to extend as far as the end stop.

22.2

Turn wheels of 2nd front axle to right by hand directly at axle until drag link (1) can be attached to 1st steering idler arm (9)

On right-hand drive vehicles

 It is not advisable to turn the wheels on the 2nd front axle using the steering wheel because the pressure always causes the steering cylinder to extend as far as the end stop.

23
