Some aluminium wheels, with very high centring, must
be fitted with the cone outside the wheel.
5. Clean the mandrel (

) before fitting
the wheel.
6. Fit the wheel (
Fig. 21 ref. 3
) with the inside of the

12.0 FITTING THE WHEEL ON THE
MANDREL
To achieve perfect balancing, the wheel must be care-
fully and properly fitted on the mandrel. Imperfect
centring will inevitably cause unbalances.
MOST IMPORTANT IS THAT ORIGI-
NAL CONES AND ACCESSORIES
ARE USED MADE SPECIFICALLY
FOR USE ON THE WHEEL BAL-
ANCER.
Wheel fitting using the cones provided is illustrated be-
low. For alternative fittings, using optional accessories,
refer to the special instructions provided separately.
12.1 Fitting of the wheel (
LIBRAK380.3DTEC
- LIBRAK430.3DTEC)
1. Remove any type of foreign body from the wheel
(
Fig. 19 ref. 3
): pre-existing weights, stones and
mud, and make sure the mandrel (
Fig. 19 ref. 1
)
and the rim centring area are clean before fitting
the wheel on the mandrel.
2. Carefully choose the cone (
Fig. 19 ref. 2
) most suit-
able for the wheel to be balanced. These accessories
must be selected according to the shape of the rim.
Position the wheel (
Fig. 19 ref. 3
), fitting the cone
(
Fig. 19 ref. 2
) on the mandrel (
Fig. 19 ref. 1
): be
careful (otherwise this could seize) until this rests
against the support flange (
Fig. 19 ref. 4
).
3. Fit the wheel with the inner side of the rim towards
the wheel balancer and against the cone.
