5.7 Mounting Tires Onto Multi-piece
Rim/Wheel Assemblies
1. Roll the tire on the foot board (the tube and flap
must be in place).
Note: O.T.R. tires and rims are very heavy and an out-
side lifting tool may be required.
For tube type only, the valve should be placed at 12
o’clock, for easier mounting.
2. Slide the tire onto the rim with the foot board or
with the bead loosener disc, if necessary.
3. Mount all the assembly components.
4. Engage one edge of the lock ring in its seat and
complete the mounting process with the bead
loosener disc.
In the initial mounting phase hold the rim edge in its
seat with a bar (fig.40).

Do not inflate the tire on the machine. This
machine is not an inflation device.
For inflation place the wheel in an approved
inflation restraint device. Refer to OSHA
standard number 1910.177.
5.8 Demounting Tractor and O.T.R. Wheels
With One-Piece Rims
These wheels may be tube-type or tubeless. The rim
has a slightly conical surface and a very high rim flange
(fig.41) which does not allow you to demount the tire
by simple pressure from the roller as described in
@5.2.

1. Remove all wheel-weights from the rim. Remove
the valve stem or core and deflate the tire completely.
2. Place the disc tool next to the rim edge and
loosen tire inner bead.
3. Loosen the outer bead in the same way, taking
care not to damage the valve stem (fig.42).

4. Lubricate both beads and the rim surface (fig.43).
