1. The tightness of the motorcycle sprocket should be appropriate. Too tight will increase power consumption and the bearings will wear out easily; too loose the sprocket will easily jump and fall off the chain. The tightness of motorcycle sprocket is: lifted or pressed down from the middle of the chain, which is about 2%-3% of the center distance between the two sprockets.

2. The motorcycle sprocket should be installed on the shaft without swing and skew. The end faces of two motorcycle sprockets in the same transmission assembly should be in the same plane. When the center distance of the motorcycle sprocket is less than 0.5 meters, the deviation can be 1 mm; when the center distance of the motorcycle sprocket is more than 0.5 meters, the deviation can be 2 mm. However, there must be no friction on the side surfaces of the sprocket teeth. If the two wheels offset too much, it will easily cause chain disconnection and accelerated wear. When replacing the motorcycle sprocket, you must pay attention to check and adjust the offset.

3. After the motorcycle sprocket is severely worn, the new sprocket and the new chain should be replaced at the same time to ensure good meshing. It is not possible to replace the sprocket or chain alone. Otherwise it will cause poor meshing and accelerate the wear of new sprocket or new chain. After motorcycle sprocket tooth surface is worn to a certain degree, it should be turned over and used in time (referring to the sprocket used with adjustable surface) to extend the use time.

4. The new motorcycle sprocket is too long or stretched after use, and it is difficult to adjust. You can remove the chain link depending on the situation, but it must be an even number. The chain link should pass through the back of the sprocket, the lock piece should be inserted outside, and the opening of the lock piece should face the opposite direction of rotation.

5. Motorcycle sprocket should be filled with lubricant in time during work. Lubricating oil must enter the matching gap between the roller and the inner sleeve to improve working conditions and reduce wear.
6. The old motorcycle sprocket cannot be mixed with the new sprocket, otherwise it is easy to have an impact in the transmission and break the sprocket.

7. When the machine is stored for a long time, the motorcycle sprocket should be removed and cleaned with kerosene or diesel, and then coated with oil or butter and stored in a dry place.
