Figure 6-18 Emptying the liquid chamber
4. Leave the acoustic wheel’s liquid chamber to dry for two days (48 hours).
Partially screw the OUT valve in place before filling the acoustic chamber again.
After the inside surface of the tire within the liquid chamber is dry, the acoustic wheel
can be refilled with liquid. For more information, see “Filling the Liquid Chamber” on
page 40.
6.5.2 Restoring the Tire’s Transparency
When the tire has become partially or totally opaque, its transparency can be restored
by removing the acoustic wheel from the scanner, removing the water from the liquid
chamber, removing the plain flange, cleaning and drying the inside of the tire, and
then letting the tire dry for 48 hours or more.
