3. REMOVAL AND INSTALLATION

3.1 REMOVAL AND INSTALLATION, WHEEL

When removing a wheel with a

cracked or damaged wheel rim,

always deflate the tyre (remove the

tyre valve) in view of possible

tensions in the wheel rim.

General

-

Only use the original DAF wheel rims

specified for the vehicle concerned.

-

Make sure that tyres of the same type are

fitted on both sides of the axle.

-

Insufficient cleaning of the mating surfaces

and/or uneven tightening of the wheel nuts

may cause vibrations during driving or

braking.

Note:

If a wheel stud is renewed, the other wheel studs

on the relevant wheel must also be renewed.

Removing the wheels
1.

Chock the wheels to prevent the vehicle

moving off.

2.

Clean the screw thread of the wheel studs

using a wire brush.

3.

Oil the wheel studs sparingly.

4.

Unscrew the wheel nuts.

5.

Fit a jack as close as possible to the wheel to

be replaced.

6.

Jack up the vehicle and, if possible, place a

support under the axle.

7.

Remove the wheel nuts and take the wheel

off the hub.

Installation of wheel
1.

Clean the fitting edge of the wheel rim by

scraping off dirt and corrosion with a scraper.

2.

Apply a thin layer of grease to the fitting

edge of the wheel hub.

3.

Also apply a thin layer of grease to the fitting

edge of the wheel rim. This grease layer

should prevent the wheel rim and the wheel

hub from becoming "rust-bound".

4.

Check whether the contact surfaces of the

wheel rim and hub are clean. Clean them if

necessary.

5.

Clean the wheel nuts and then apply a drop

of oil between the thrust washer and the nut.

6.

Also apply a drop of oil to the first turn of the

wheel stud screw threads.

7.

Fit the wheel nuts and tighten them evenly

according to the sequence in the illustration.

A pneumatic spanner may be used for this

purpose, but its tightening torque is not very

reliable.

It will therefore be necessary to retighten the

wheel nuts to the specified tightening torque.

For the prescribed tightening torque, see

'Technical data'.

Note:

Wheel nuts should always be tightened and

retightened in cold condition. However,

tightening wheel studs in extreme cold

should be avoided.

8.

Check the tyre pressure.

9.

Retorque the wheel nuts with a torque

wrench after 100 km. If new wheel studs are

fitted, they need additional retorquing after

500 km.

Removal and installation, Trilex wheel
1.

If the vehicle is equipped with special

adapter rings for the assembly of Trilex rims

on the disc wheel hubs, these adapter rings

should be installed on the hub in the same

way as a disc wheel. This also applies to the

tightening torque and the retightening.

2.

The same instructions which apply to a

standard wheel also apply to the removal

and installation of a Trilex rim on a Trilex hub

or adapter ring, except for the attachment nut

tightening sequence and tightening torque.

3.

Tighten the nuts evenly in the sequence

shown in the drawing.

A pneumatic spanner may be used for this

purpose, but its tightening torque is not very

reliable.

It will therefore be necessary to retighten the

wheel nuts to the specified tightening torque

using a torque wrench. For the prescribed

tightening torque, see 'Technical data'.

4.

Retorque the wheel nuts with a torque

wrench after 100 km. If new wheel studs are

fitted, the nuts need additional retorquing

after 500 km.
