Order the ring from your hardware manufacturer.

Adjust the tyre pressure (see MR of the vehicle

concerned, 35A, Wheels and tyres ).

I - PREREQUISITES FOR WHEEL BALANCING

Perform a road test of at least 1.2 miles (2 km) be-

fore the wheel balancing operation to prevent a flat

spot forming on the tread when the vehicle is statio-

nary.

Wheel balancing is a measurement operation.

Several conditions must be met to achieve a reliable

result in a single operation.

After the road test:

The wheel balancer must be installed in accordance

with the manufacturer's instructions.

- raise the vehicle immediately,

- leave the four wheels hanging free,

It is essential that the machine is recalibrated at the

intervals specified by the manufacturer.

- release the parking brake.

Never grease the threaded shaft.

Check the condition of the supports, centring com-

ponents and mountings.

Replace any faulty parts (see manufacturer's ins-

tructions).

The wheel and the wheel balancer must be clean.

Driver's complaint

If the wheels are not correctly balanced this causes

the steering wheel and/or the vehicle floor to vibrate.

The vibrations occur between 54 mph (90 km/h)

and 90 mph (150 km/h) .

II - WHEEL REMOVAL AND WHEEL BALANCING

Place the vehicle on a two-post lift immediately after

the road test (see MR of the vehicle concerned,

02, Lifting equipment ).

Loosen the wheel bolts.

Raise the vehicle.

Release the parking brake.

Check that the wheels are not damaged due to acci-

dental impacts (if they are, replace the damaged

components),

Position the wheel valves at the top.

Fit tool pedal press .

Remove:

- the wheel bolts,

- the wheel.

Always clean the bearing surfaces of the wheel and

the disc (or drum).

To reproduce the exact vehicle wheel assembly, it is

essential to fit a ring ( 1 ) with a diameter of 60 mm on

the wheel balancer.

Make sure that the wheel balancer bearing surface

and all the centring equipment (ring, thrust plate,

etc.) are kept clean.

There are 3 types of weights:

Try not to scratch the (alloy) wheel rim with the

wheel tightening device.

113742

( 2 )

Alloy wheel rim with ﬂange

105871

( 3 )

Alloy wheel rim without ﬂange

The wheel is fitted on the wheel balancer as follows:

( 4 )

Steel wheel rim with ﬂange

-( 5 ) wheel balancer back-plate,

In certain countries it is prohibited to use lead wei-

ghts. Instead, ZAMAK weights are recommended.

-( 6 ) ring, diameter 60 mm ,

Only use weights provided by the Parts Department.

-( 7 ) wheel,

-( 8 ) wheel tightening device (certain alloy wheel

rims need a device 200 mm in diameter to ensure

correct tightening),

-( 9 ) exterior plane of the wheel.

Place the valve at the top of the wheel balancer,

then carry out the tightening procedure.

Remove any stones which may be jammed in the

tyre treads.

Enter the parameters for the wheel into the wheel

balancer device.

Operate the wheel balancer and check the wheel

balance, which should be 0 g on each plane of the

wheel.

If this is not the case, remove the old balancing wei-

ghts and repeat the wheel balancer procedure,

checking that the wheel balance equals 0 on each

wheel plane.

100682

Pretighten the wheel bolts (30 Nm) with the wheel

hanging freely, starting with the lower bolts ( 10 ) and

finishing with the upper bolts ( 11 ).

Remove pedal press .

WARNING

To avoid loss of the balancing weights, use only

weights appropriate for the wheels on the vehi-

cle.

III - REFITTING THE VEHICLE WHEELS

Refit the wheel onto the vehicle in the same position

it was removed with the valve at the top.
