If the new sprockets are too long or they are stretched after use, they are difficult to adjust. The chain links may be removed if necessary, but they must be even. The chain link should pass through the back of the sprocket, and the locking plate should be inserted outside. The opening of the locking plate should be in the opposite direction of rotation.
Sprockets should be filled with lubricants on the job. Lubricants must enter the clearance between the roller and the inner sleeve to improve working conditions and reduce wear.
Old sprocket cannot be mixed with some new sprocket, otherwise it is easy to produce impact in the drive and break the sprocket.
When the machine is stored for a long period of time, the sprocket should be removed and cleaned with kerosene or diesel, and then painted with oil or butter in a dry place.
The sprocket should be mounted on the shaft with no wobble and skew. In the same transmission assembly, the end faces of the two sprocket wheels should lie in the same plane. When the sprocket center distance is less than 0.5 meters, it can deviate by 1 mm; when the sprocket center distance is more than 0.5 meters, it can deviate by 2 mm. However, it is not possible to have friction sprocket side phenomenon, if the two-wheel deflection is too large, it is easy to generate de-chaining and accelerated wear. In the replacement of sprocket must pay attention to check and adjust the offset.
