Tire pressure sensor
1. Front left wheel pressure sensor "6222", front right wheel "G223", rear left wheel "G224" or rear right wheel "G225"; every time you change your tires, replace the valve core: when using a used tire pressure sensor, the union nut, valve core, sealing ring, sealing washer, and valve cap must be replaced; after installation, conduct a visual inspection to ensure the sensor is firmly seated in the rim; damaged sensors should be replaced; do not clean sensors with jets of steam or a strong jet of compressed air.
2. Valve core: damaged valves should be replaced; when changing a tire, also replace the valve core.
3. Sealing washer: When installing a new sealing washer, avoid squeezing the valve body when holding it; if the connection is broken, replace the tire pressure sensor.
4. Sealing ring; when installing a new seal. rings to avoid squeezing the valve body when holding, if the connection is broken, replace the tire pressure sensor.
5. Rim.
6. Union nut: 8 Nm.
7. Cap: Use only original caps from the repair kit; do not use comfort caps.
Changing tires
Every time you change your tires, the nickel-plated valve core should be replaced. The tire pressure sensor can be reused. For safety reasons, after using tire sealant, you should replace the tire pressure sensor and clean the rim. Reduce tire pressure by removing the nickel-plated valve stem. Remove the tire. When replacing the tire, also replace the valve core. Do not clean sensors with steam jets or strong jets of compressed air. When using a used tire pressure sensor, visually inspect the connection between the sensor and the metal valve for defects. Replace damaged sensors. When installing a new sealing washer and a new seal. rings to avoid squeezing the valve body when holding. If the connection is broken, replace the tire pressure sensor. Install the tire. Screw in a new, nickel-plated valve core. Inflate the tire. Balance the wheel.
Removing the tire: Roll the tire or press it down. When using tire pushers, first push the tire on the side opposite the valve. Do not use pry bars in the shaded area "a". Position the pry head near the valve so that the mounting bar can be positioned at 30° "b" near the valve. Only then press the tire in the valve area.
Tire installation: Do not use push-up tools in the valve area. Position the tire pressure sensor approximately 180° relative to the pressing head. Press the tire into the rim at a point approximately 90° from the "arrow" pressing head. Mount the tire.
Removal and installation the tire pressure sensor
Unscrew the union nut "1". Remove the pressure sensor "2" from the rim base.
Installation
Be sure to replace damaged sensors. When using used tire pressure sensors, check the connection between the tire pressure sensor and the valve for damage. For safety reasons, after using tire sealant, replace the tire pressure sensor and clean the rim. Do not clean tire pressure sensors with steam or high-pressure air jets. When installing a new sealing cuff and sealing washer, avoid squeezing the valve body when holding (risk of damage to the antenna connection). Insert sensor "2" with a new seal. ring and sealing washer from the inside through the disk and press the seal. ring in the center of the valve hole. Perform a visual inspection to ensure that the valve stem is centered in the valve bore. Screw the union nut "1" onto the tire pressure sensor "2". Press the sensor into the rim and hold it there. When tightening the union nut, avoid applying strong pressure to the union nut and tool. Press the tire pressure sensor "1" to the bottom of the rim and tighten the union nut. After installation, the tire pressure sensor should fit firmly against the bottom of the rim. The "arrow" sealing washer is slightly deformed when tightened.
