Installing Liquid Ballast in Tires
                      
Using the Air Liquid Adapter Kit
 |
The Air/Liquid Adapter Kit permits fast filling of tires with fluid for ballast. Button valve on side releases air displaced by fluid. Connects 3/4" standard garden hose to air/liquid tractor stem "TR 218A/220A" and comes with 2 extra bushings to accomodate "TR 13" and "TR 15" stems.

1. Support tire and wheel assembly off ground and rotate assembly to position valve core on top. |
|
2. If the tire valve has a core housing like those found on tractor tires, remove the valve core to deflate the tire and then remove the core housing. Otherwise, for tires that do not have valve core housing, click here. |
 |
|
 |
3. Install water hose on the large end of the Air/Liquid Adapter. Make sure hose is tightly connected. |
|
4. Leave the rim nut on the stem and attach the Air/Liquid Adapter to the valve stem base. |
 |
|
5. Turn on water supply. As water is filling the tire and taking up space, additional air pressure will develop. The added air pressure needs to be released to keep the pressure from becoming excessive and so that water will continue to flow. To release pressure, turn off water supply and slowly push the pressure release button on the adapter. This will release both water and air at first. After a short time, water will stop being released and only air will continue to be released. When there is no more air pressure, release button and turn on water supply again. Repeat this process of releasing air pressure until the water level reaches the valve or until the tire is 75% filled with liquid. Then turn off water supply, press button to release any remaining air pressure, remove the Air/Liquid Adapter, and reinstall the core and/or core housing. Finally, add air to tire until air pressure is at the factory recommended level. |
| Special instructions for tires without valve core housing: |
 |
|
 |
For tires without valve core housing, remove valve core and deflate tire. |
|
Install small adapter on valve stem threads. Then install the Air/Liquid Adapter as shown in the picture to the left. Then install water hose on the large end of the Air/Liquid Adapter. Make sure hose is tightly connected. Proceed to step #5 above. |
Using the Hydro-inflation Core Ejection Tool
 |
The Hydro Inflation Core Ejection Tool is used with the Air-powered Diaphragm Pump . The Hydro Inflation Core Ejection Tool will remove and install the core housing while mounted on the valve stem base. The tool has additional adapters to be used with small stems, tractor stems, and large bore stems.
The Hydro Inflation Core Ejection Tool is an all-brass tool that permits fast filling of tires with liquid ballast solutions. Includes bushings to fit tube and tubeless versions of standard, large, and super-large-bore air/liquid valves with removable core housings. |
 |
|
 |
1. The Hydro Inflation Core Ejection Tool apparatus will thread over the base of the air/liquid TR218/220A type valve stems. |
|
2. The union can be installed while connected to the rest of the Hydro Inflation Core Ejection Tool, or it can be installed separately.
|
 |
|
 |
3. To remove the core housing, gently push on the end of the hand wheel and turn counterclockwise. This will remove the core housing from the base of the stem. |
|
4. After several revolutions, pull back on the hand wheel. This will pull the core housing from the base to the back of the ejection tool, making the tire ready for filling or removal of liquid. |
| What happens inside? |
 |
|
 |
The sleeve is split to slide over the core housing. |
|
Pushing on the hand wheel forces the sleeve over the housing. |
  |
|
These two drawings illustrate
the idea of "valve level." With the tire
positioned so that the valve is at the top
of the rim, the tire is approximately 75%
filled with liquid when the liquid
reaches "valve level." |
| Using adapters |
 |
|
 |
When the tire has a TR-13 or TR-15 stem, install
the small bore core removal plug in the end of
the core ejector. This will allow you to remove
and reinstall just the valve core. You will also
need to use the adapter for the standard valve. |
|
This picture shows the adapter and the valve core. |
