To install or remove liquid ballast from a tire, a liquid ballast pump will be required.
Diaphragm Liquid Ballast Pump
10'L supply hose and 15'L fill/evacuation hose
Switching control valve for easy reversal of liquid transfer
Includes core ejection tool, pressure gauge and fill chart
Can be operated with a standard air compressor at 40-60 psi
Follow the instructions below to learn how to insert or remove liquid ballast. To keep liquid ballast from freezing, a calcium chloride solution can be used. Click here for instructions on using calcium chloride (CACL2).
Turn tire and rim so valve is on top. Remove rim nut from valve stem. Thread end of core ejection tool on rim nut threads and tighten. Push the rod assembly in until it fits tight over core housing. Turn counterclockwise to remove core housing. This will bleed air back through to container.
When air is out of the tire, turn pump control lever to fill. As tire is being filled, pressure will build inside. When the tire is approximately 1/2 full, turn control lever to evacuate and this will force air pressure from tire to storage container. When pressure has been released, turn control lever to fill and fill tire to valve level (75%). DO NOT fill tire completely.
After fluid in tire is valve level, stop pump and turn core tool clockwise pushing forward to thread core housing in tube stem. Turn control level on pump to evacuate to release any pressure. Pull back on plunger rod (core ejection tool); this will release core housing. Remove core ejection tool. Check air pressure with air/liquid gauge (Item No. 8D) and set to manufacturer's specifications. Install rim nut and valve cap.
Air/Liquid Tire Gauge
Calibrated in 1-lb. increments
5 - 45 p.s.i.
Rotate tire so valve stem is at bottom. Remove rim nut from valve stem. Thread end of core ejection tool on rim nut threads and tighten push rod assembly in until it fits tight over the core housing. Turn counterclockwise to remove core housing.
After core housing is removed, turn pump control lever to evacuate. This will pull fluid from tire and pump it into a barrel or container. After fluid is removed from tube, tire can be removed for repair.
Calcium chloride is a salt mixture to add to water when filling tires with liquid. This mixture will keep the water from freezing in cold climates. Check the liquid ballast chart for your tire size. If you are unsure how much solution you need, please call 1-800-874-4755.
EXAMPLE - 11.2x38 on 10"W rim
Water only will freeze at 32°F and add a weight of 300 lbs.
109 lbs. of 77% calcium chloride salt flake (Type 1) and 31 gallons of water will freeze at -12°F and add a weight of 368 lbs.
145 lbs. of 77% calcium chloride salt flake (Type 1) and 29 gallons of water will freeze at -50°F and add a weight of 387 lbs.
Mix calcium chloride and water in a tub or barrel (plastic works best). Fill container about half full of water and add calcium chloride flakes. Stir immediately or flakes will clump and harden. After all flakes are dissolved in water, add rest of water per mixture and stir.
50-lb. bag Calcium Chloride
83%-87% test CaCl2 salt flakes
Can also be used to melt snow
NOTE: Most tire ballast charts are based on 77% CACL2. This 83%-87% formulation allows you to reduce the CACL2 amount by 18-20%.
