3. Safety Information

• Always wear appropriate personal protective equipment, such as gloves and eye protection, when working with tires and wheels.
• Ensure the vehicle is properly supported and secured before beginning any work on tires.
• Deflate the tire completely before attempting to remove or install a valve stem.
• Improper installation can lead to air leaks and tire failure, posing a safety risk. If unsure, consult a qualified technician.

4. Setup and Installation

The installation of the Jyving TR570 valve stem involves removing the old valve and replacing it with the new one. This process requires careful attention to ensure a proper seal.

Required Tools (Not Included):

• Valve stem removal tool
• Valve stem installation tool (if applicable)
• Wrench (for securing the nut)
• Tire pressure gauge
• Soapy water solution (for leak detection)

Installation Steps:

1. Prepare the Tire: Ensure the tire is completely deflated. If the tire is still on the vehicle, lift and secure the vehicle safely.
2. Remove Old Valve Stem: Use a valve stem removal tool to carefully extract the old valve stem from the rim hole. Clean the rim hole thoroughly to remove any debris or corrosion.
3. Inspect New Valve Stem: Verify that the new Jyving TR570 valve stem, grommets, valve core, and cap are free from damage.
4. Insert New Valve Stem: From the outside of the rim, insert the brass body of the new valve stem through the 16mm (5/8 inch) rim hole. Ensure the rubber grommet is properly seated against the rim.
5. Secure the Valve Stem: From the inside of the rim, place the washer and thread the securing nut onto the valve stem. Tighten the nut firmly with a wrench to create a tight seal, but do not overtighten, as this can damage the rubber grommet.
6. Install Valve Core and Cap: Screw the valve core into the stem and then securely attach the valve cap.
7. Inflate Tire: Inflate the tire to the manufacturer's recommended pressure.
8. Check for Leaks: Apply a soapy water solution around the base of the valve stem and the valve core. Look for bubbles, which indicate an air leak. If leaks are detected, re-check the installation and tightness of the nut.

5. Operating

Once installed, the valve stem's primary function is to allow for tire inflation and deflation while maintaining air pressure within the tire. Proper operation involves regular monitoring of tire pressure.

• Check Tire Pressure Regularly: Use a reliable tire pressure gauge to check tire pressure at least once a month, and before long trips. Always check when tires are cold.
• Keep Valve Caps On: Ensure valve caps are always securely tightened. They protect the valve core from dirt, moisture, and potential damage, and provide an additional seal against air loss.

6. Maintenance

Regular maintenance helps prolong the life of your valve stem and ensures optimal tire performance and safety.

• Inspect for Damage: Periodically inspect the valve stem for any signs of damage, cracks in the rubber, or corrosion on the brass.
• Check for Leaks: If you suspect a leak, perform the soapy water test as described in the installation section.
• Replace Valve Core: If a leak is detected from the valve core, it can often be replaced independently without replacing the entire stem.
• Replace Valve Stem: Valve stems should be replaced whenever new tires are installed, or if any damage is observed.

7. Troubleshooting

Most issues with tire valve stems relate to air leaks. Here are common troubleshooting steps:

• Air Leak at Valve Stem Base: If bubbles appear when applying soapy water around the base of the stem, the securing nut may be loose, or the rubber grommet may be damaged. Tighten the nut or replace the valve stem.
• Air Leak from Valve Core: If bubbles appear from the top of the valve core, it may be loose or faulty. Try tightening the valve core with a valve core tool. If the leak persists, replace the valve core.
• Damaged Valve Cap: A damaged or missing valve cap can allow dirt and moisture into the valve core, potentially causing leaks. Ensure the cap is always present and securely tightened.
