Mounting Tubeless And Supersingle Tyres; Demounting Wheels For Earthmoving Machines With A Side Ring - Corghi MONSTER AGTT Manuel D'utilisation

MOUNTING TUBELESS AND
SUPERSINGLE TYRES
When mounting tubeless tyres, place the rear bead on the rim edge, use the tool arm,
moving the tool tangent to it and move it closer to the rim� The rear bead will go beyond
the rim edge� When mounting the front bead, tighten the pliers on the front edge of the
rim above the tool (fig�41), position the tool with the reference flush with the rim edge
and turn the turntable clockwise�
Pay attention to the correct position of the front bead in the rim well�
In this way, the tyre will be completely mounted�
N�B� To mount the tyre correctly and without any damage, lubricate the beads and the
shoulder of the rim abundantly�
DEMOUNTING WHEELS FOR
EARTHMOVING MACHINES
WITH A SIDE RING
Using the disc tangency command, position the rim tangentially to the bead breaker disc�
Keeping the tyre rotating, press on the front bead until freeing the side ring and the lock
ring (fig�42)� If necessary, position the disc on the side ring and push it towards the tyre
(fig�43)� This operation can be made easier thanks to the hydraulic movement of the bead
breaker disc, which always guarantees perfect bead breaking inclination (fig�44)� The ring
will be freed from the side ring and will be extracted using the specific lever (fig�45)
Repeat the bead breaking operation on the rear side as shown in (fig�46) and continue until
the tyre comes out, with or without the side ring� It is recommended to place the tyre on
the ground� This makes it possible to remove the side ring without the wheel falling�
N�B� For wheels that are particularly hard and locked on the side ring, 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, it is important
to use a hydraulic bead breaker disc, which makes it possible to identify the proper
inclination for inserting the disc between the rim edge and the bead until just touching
the shoulder of the rim�
