Mounting Agriculture Wheels - Corghi AGTT 1600A Manuel D'utilisation

REAR BEAD DEMOUNTING:
- Use the tool arm lifting and tool unit rotation controls to move it to the other side of the
wheel. With the semiautomatic version, rotation is done using the specific lever (Fig.
24a).
- At this point, turn the turntable.
- Move the bead breaker disc near the bead and start to push it outward. Be careful that
the bead does not tip on the rim edge while it is being pushed out. If necessary, as soon
as the disc has passed the rim edge, lower the turntable a few cm. This will decrease
the bead tension and make it easier to demount the wheel (Fig. 32).
NOTE
For some types of rims, such as with a reduced well, a double well or skidder, a demount-
ing tool and a manual lever must be used.
- If necessary, activate the manual search mechanism to insert the tool between the rear
bead and the rim as shown in (Fig. 32a) until hooking the bead.
- Turn the turntable and use the shaped profile of the tool to push the bead forward until
it bypasses the rim edge.
- Insert the lever between the bead and the rim edge and turn the turntable in an anti-
clockwise direction until tyre demounting is complete.
- If necessary, return the tool to a horizontal position.
To hook the bead in the case of narrow rims with a reduced well, it may be helpful to turn
the turntable in an anticlockwise direction.

moUnTInG AGrICUlTUrE WHEElS

Tighten the pliers on the front edge of the rim and position the tool in the work position
(Fig. 33). Turn the tool unit using the specific control or lever if necessary.
Move the rear bead of the tyre beyond the pliers and the tool. Turn the wheel clockwise
(Fig. 34). If necessary, move the tool near the rim to make complete mounting easier.
To make it easier to insert the inner tube (Fig. 35) place the tyre on the floor.
For the front bead, position the tool near the valve with the reference mark flush with the
rim and tighten the pliers above the tool (Fig. 36), then turn the wheel clockwise.
N.B. For tyre mounting and demounting operations, it is a good idea to lubricate the
beads and the rim in the wheel area with grease.
NOTE
With rims with a dual well, the use of the accessory DV120 (Fig. 37) is recommended.
With skidder rims the use of DV120 is recommended together with the skidder terminal,
both of which are optional accessories.
