5.6 Demounting tires from multi-
piece rim/wheel assemblies
The multi-piece rim/wheel assembly can be in two or
more pieces (Fig.5.6-1).
1.
Remove all wheel-weights from the rim.
Remove the valve stem or core and deflate the tire.
INSERT THE TOOL LOCKING PIN (1,Fig.5.0-1)
BEFORE USING THE DISC TOOL ON RIM WHEELS.
2.
Position the tool close to the rim edge (Fig.5.6-2).
When the lock ring is stuck to the bead, (on the O.T.R.
tires) to make it to break the bead, it is necessary to
hold it to the rim with the appropriate clamp #4007611
(on request).
3.
Turn the chuck counter-clockwise and the break bead
as described in @5.2.1.-5.2.3.
Do not lubricate.
4.
To remove the lock ring, squeeze one edge with the
proper bar and place the bead breaker disc as shown
in Fig.5.6-3.
5.
Turn the chuck clockwise (or counter-clockwise) until
the lock ring is completely removed.
NO ONE SHOULD STAND IN FRONT OF THE WHEEL
WHEN REMOVING THE LOCK RING
THE LOCK RING MAY BE LOADED WITH AN ELASTIC
ENERGY SUFFICIENT TO PROPEL ITSELF FROM
ITS SEATING.
MOVE ANYBODY PRESENT AWAY AND STAND IN
A SAFE POSITION IN RELATION TO THE WHEEL,
TO AVOID ANY DANGER DUE TO FLYING OBJECTS.
Continue to demount all components of the rim manually
or with the disc tool.
6.
When breaking the inner bead be sure not to damage
the valve stem (Fig.5.6-4).
