2. INSPECTION AND ADJUSTMENT

2.1 INSPECTION AND ADJUSTMENT, SWIVEL AXLE PLAY

Inspection of swivel axle play
1.

The vehicle should have its wheels on the 

ground.

Note:

If the wheels have been removed from the 

front axle, e.g. for overhaul purposes, the 

swivel axle will hang at the axle end.

In that case, the swivel axle should be 

supported by a jack, pushing the swivel axle 

against the bottom of the axle end.

2.

Using a feeler gauge measure the distance 

between the shim and the swivel axle at (A). 

Take measurements in several places.

Compare the reading with the admissible 

play. See 'Technical data'.

Note:

The play should be about equal along the 

entire circumference of the axle end. If the 

play is not equal, this is caused by radial play 

in the needle bearings. If the radial play of 

one of the values measured along the 

circumference differs from the specified 

value, the needle bearings should be 

replaced, see the chapter 'Removal and 

installation'.

If an excessive axial play is measured along 

the entire circumference of the axle end, this 

is probably caused by a worn swivel axle 

thrust bearing.

Adjusting the swivel axle play, thrust bearing, 
split version
1.

Remove the swivel axle from the axle end. 

See 'Removal and installation'.

2.

Degrease and clean the thrust bearing.

3.

Check the thrust bearing for wear or 

damage. If in doubt, replace the thrust 

bearing.

4.

Check the machined surfaces of the axle end 

and the swivel axle for damage.

5.

Remove the dust seal (1) from the thrust 

washer (2).

6.

Assemble the thrust bearing without 

greasing it and without the dust seal (1). 

Make sure that the cam at the bottom of the 

bearing ring (3) falls in the recess of shoulder 

ring (4). See the arrows in the drawing.

7.

Fit the swivel axle with its original shim on the 

axle end.

8.

Fit the king pin. Hand tighten the nut.

9.

Place a jack under the swivel axle, pushing 

the thrust bearing against the axle end.

10. Using a feeler gauge measure the gap 

between the shim and the swivel axle.

If necessary, use a shim with a different 

thickness until the specified axial play is 

achieved. See 'Technical data'.

Note:

The shim thickness can also be determined 

using the formula in the drawing.

11. Remove the swivel axle from the axle end.

12. Disassemble the thrust bearing and grease 

the top side of bearing ring (3) (ribbed side 

with lubricating grooves).

13. Fit a new dust seal (1) to the thrust washer 

(2).

Make sure that the top of the dust seal is 

positioned under the top of the thrust 

washer.

14. Install the swivel axle with the correct shim 

on the axle end. See 'Removal and 

installation'.

15. Measure the play again.
