2.6 INSPECTION OF TOE-OUT WHEN TURNING

Measuring the toe-out while the vehicle is turning 

(especially for vehicles with two steerable front 

axles or a leading rear axle) is a method of 

inspecting the setting of the steering gear.

During this measurement, the inside wheel of the 

front steerable axle is turned 30

 inwards. The 

wheel deflections of the other steerable wheels 

are then measured.

Work safely and block the vehicle so 

that it cannot slide off the turning 

plates.

Inspection of toe-out when turning
1.

Engage the vehicle's parking brake and 

place chocks in front of and behind the rear 

wheels.

2.

Jack up the steerable axles and place 

turning plates under the centre of the wheels.

Only use turning plates which allow for wheel 

displacement caused by the wheel offset.

3.

Place the wheels in the "straight ahead" 

position and lower them until they rest on the 

turning plates. Set the turning plates to zero 

degrees.

4.

Turn the steering wheel until the inside wheel 

of the front steerable axle (wheel 1 in the 

drawing) reaches a 30

 angle.

5.

Fix the steering wheel in this position and 

note down the wheel deflections of the 

remaining steerable wheels.

6.

Carry out this measurement on both the left 

and the right side.

For the correct values, see 'Technical data'.

If a large deviation is measured, the cause 

should be traced. Inspect the wheel 

deflection using wheel alignment equipment.

The deviation may, for example, have been 

caused by a collision, during which 

components were bent. If so, the remaining 

steering gear components should be 

inspected carefully.

2.7 INSPECTION AND ADJUSTMENT, STEERING ROD

Work safely and block the vehicle so 

that it cannot slide off the turning 

plates.

Inspecting the steering rod adjustment
1.

Engage the vehicle's parking brake and 

place chocks in front of and behind the rear 

wheels.

2.

Jack up the steerable axle and place turning 

plates under the wheels.

Only use turning plates which allow for wheel 

displacement caused by the wheel offset.

3.

Place the wheels in the "straight ahead" 

position and lower them until they rest on the 

turning plates.

4.

Measure the (mis)alignment of the wheel to 

which the steering rod is connected. This can 

be done using wheel alignment equipment or 

by measuring the distance from the wheel 

rim to the spring leafs at the front and rear of 

the wheel. The distances at the front and rear 

of the wheel should be equal.

5.

Check using the markings (A) and (B) on the 

steering box that the input shaft of the 

steering box is in the central position. For the 

permitted deviation, see 'Technical data'.

6.

Adjust the steering rod length, if the values 

deviate too much.

If a large deviation is measured, the cause 

should be traced. 

The deviation may, for example, have been 

caused by a collision, during which 

components were bent. If so, the remaining 

steering gear components should be 

inspected carefully.

Adjusting the steering rod
1.

Loosen the bolt of the clamping bracket on 

the steering rod.

2.

Remove the steering rod from the steering 

rod arm. See 'Removal and installation'.

3.

Place the steering box in the centre position 

by aligning the markings.

4.

Set the correct length of the steering rod by 

screwing the ball end in or out.

If the vehicle is unloaded, turn the ball end 

one additional turn.

Make sure that the threaded end of the ball 

end is not pushed too far from the steering 

rod. The clamping bracket should always 

fully engage the screw thread of the ball end 

(see drawing).

Note:

If the length is not correct because the ball 

end can only be rotated one full turn, get as 

close as possible to the correct length. A 

steering rod that is too long is preferable to a 

steering rod that is too short.

5.

Inspect the thread of the ball end for 

damage.

Fitting a new self-locking nut to a 

ball end with a damaged thread may 

lead to dangerous situations.

6.

Install the steering rod in the steering rod 

arm. See 'Removal and installation'.

7.

Thoroughly clean and check the clamping 

bracket bolt. A corroded or damaged bolt 

must be replaced.

Replace the self-locking nut.

8.

Tighten the clamping bracket bolt to the 

specified tightening torque. See 'Technical 

data'.

9.

Check the steering wheel position when it is 

in the "straight ahead" position. If necessary, 

adjust the position by changing the position 

of the steering wheel on the steering shaft.

10. Calibrate the EMAS system in case of a 

steered trailing swivel axle.
