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.
