Clamping Reverse Drop Center Wheels
HINT: Identify reverse drop center wheels while you are loosening
the bead of the tire. This will help you properly identify the
proper procedure to use before demounting the tire.
Wheels with a reversed offset drop center must be mounted on the tire changer
upside down to remove the tire from the rim without damage.
Remove the wheel centering support before inverting wheel on clamps as follows:
Using a 36mm or 1 7/16 inch open end wrench, loosen the base of the wheel
centering support.
With bead lever, pry up on the center support spring to allow extra width to
insert open end wrench.
Rotate the wheel centering support counterclockwise until it is free from the
TC3500.
Lift the wheel centering support, removing it from the TC3500.
Store support in accessory brackets on left side of base.
Re-install wheel centering support after completing the tire changing procedure.
