Hitch Pin
Note:
If equipped, use disk-assist in upper position
to press down on tire sidewall in front of mount/
demount tool. It will aid in locating the bead lifting
tool over forward end of mount/demount tool and
below the top bead of the tire (figure 11).
13.
Depress the table top pedal to rotate the wheel.
The Duckhead demount tool will guide the tire bead up
and over the edge of the wheel. Continue rotation until
the upper tire bead is demounted.
Figure 12 - Demount Upper Bead
Note:
Push down on tire (if equipped, use Robo-
Arm
®
) across from the demount tool during table
top rotation to utilize drop center area of the
wheel. This reduces tensional force on the top or
first bead during demount.
14.
Lift and hold the tire at an angle so that the lower
bead is resting in the drop center directly across from
the demount tool, and is loose below the demount tool
(figure 14). Insert the smooth curved end of the bead
lifting tool down over the forward end of the mount/
demount tool and below the lower bead. Lift the bead
up and over the knob on the demount tool (figure 13).
Figure 13 - Guide Lower Bead Over Knob On Demount Tool
Note:
If equipped, use disk-assist in lower position
and clear of table top rotation to aid in pushing up
on lower bead of the tire (figure 14. This helps the
tire to not slide out of drop center and back on to
the rim.

Note:
If equipped, use the disk-assist to aid in
changing large diameter tires. When moving the
disk-assist from the upper position to the lower
position, it may be necessary to stow the disk-
assit away (figure 15) by removing the hitch pin.
