DEMOUNTING
WHEELS FOR
EARTHMOVING
MACHINES AND WITH
A SIDE RING
Using the disc tangency command,
position the rim tangentially to the bead
breaker disc.
Keeping the tyre rotating, press with the
bead breaker disc on the front bead until
freeing the lock ring that is extracted
with the specific lever (A, Fig. 39).
If necessary, place the disc on the side ring
and press towards the tyre (fig.40).
Repeat the bead breaking operation on
the rear side as shown in Fig. 41 and
continue until the tyre comes out, with
or without the side ring.
To prevent the side ring from detach-
ing with the tyre, fasten the side ring
to the wheel using the clamps supplied
with the machine, before breaking the
tyre bead.
N.B. If the side ring is stubbornly fixed
to the rim, demount the tyre with the
side ring still attached.
To remove it, fix it to the turntable like a
normal rim and break it from the rear.
For a good bead breaking result, both
in the front as well as in the rear, insert
the bead breaker plate between the rim
edge and the bead until just touching
the shoulder of the rim.
N.B. To facilitate the bead breaking procedure, adjust the inclination of the bead
breaker disc (G, fig.11) with the relative hydraulic control.
