Matters needing attention for wheel hub operation device The torque should be appropriate

Points to note for wheel hub application device The torque should be suitable for the application and device of the wheel hub bearing. Please pay attention to the following items: 1. In order to ensure maximum safety and reliability, it is recommended that you always check the wheel hub bearing regardless of the age of the vehicle. ——Pay attention to whether the bearing has early warning signs of wear: including any collision noise during rolling. Mechanical seal factory or suspension combination wheel decelerate abnormally when turning. For rear-wheel drive vehicles, it is recommended that the front wheel hub bearings should be smoothed when the vehicle travels to 38,000 kilometers. When replacing the brake system, check the bearing and replace the oil seal. 2. If you hear the noise announced at the hub bearing part, the most important thing is to find the location of the noise. There are many moving parts that may be noisy, and maybe some rolling parts and non-rolling parts are touching. If it is confirmed that the noise is in the bearing, the bearing may be damaged and needs to be replaced. 3. Because the working conditions of the front wheel hub causing the bearings on both sides to fail are similar, even if only one bearing is damaged by the mechanical seal of the pump, it is recommended to replace it in pairs. 4. Wheel hub bearings are more sensitive. In any case, you need to choose the right method and suitable tools. In the process of storage, transportation and installation, the bearing components must not be damaged. Some bearings require greater pressure to press in, so special tools are required. Be sure to refer to the car production clarification book. 5. The bearing should be installed in a clean and tidy environment. The entry of fine particles into the bearing will also shorten the service life of the bearing. It is very important to maintain a clean environment when replacing bearings. It is not allowed to hit the bearing with a hammer, and be careful not to drop the bearing on the ground (perhaps the similar treatment is improper). The condition of the shaft and the bearing seat should also be checked before the installation. Even minor wear will cause poor cooperation and then cause the early failure of the bearing. 6. For the hub bearing unit, do not attempt to disassemble the hub bearing or adjust the seal ring of the hub unit, otherwise the seal ring will be damaged and water or dust will enter. Even the raceways of the sealing ring and the inner ring are damaged, causing permanent failure of the bearing. 7. There is a magnetic thrust ring in the sealing ring of the bearing equipped with ABS device. This thrust ring cannot be bumped, impacted or collided with other magnetic fields. Take them out of the packaging box before the device and keep them away from magnetic fields, such as motors or power tools used. When installing these bearings, observe the ABS alarm pin on the outer dial through a road condition test to change the operation of the bearings. 8. For wheel hub bearings equipped with ABS magnetic thrust ring, in order to determine which side the thrust ring is installed on, a light object can be used to approach the edge of the bearing, and the magnetic force generated by the bearing will attract it. When installing, point the side with the magnetic thrust ring toward the inside, facing the sensitive element of the ABS. Note: Incorrect device may cause the function of the brake system to fail. 9. Many bearings are sealed, and this type of bearing does not require lubricating grease during the entire life span. Other unsealed bearings, such as double-row tapered roller bearings, need to be greased and smooth when installed. Because the size of the inner cavity of the bearing is different, it is difficult to determine how much grease to add. The most important thing is to ensure that there is grease in the bearing. If there is too much grease, the remaining grease will leak out when the bearing rolls. General experience: When installing, the total amount of grease accounts for 50% of the gap in the bearing. 10. When the lock nut is installed, because the bearing type is different from the bearing seat, the size of the torque is very different. Pay attention to the relevant clarifications.
