Heavy Duty Motorcycle Chains Manufacturers introduced that the tightness of the sprocket should be appropriate during the use. Too tight will increase power consumption and the bearings will wear out; if the sprocket is too loose, the sprocket will easily jump and fall off the chain. The tightness of the sprocket is: lifted or pressed down from the middle of the sprocket, about 2%-3% of the center distance between the two sprocket. The sprocket should not swing and skew when installed on the shaft.

When the sprocket is severely worn, the new sprocket and the new sprocket should be replaced at the same time to ensure good meshing. The new sprocket is too long or stretched after use, which is difficult to adjust. You can remove the chain link depending on the situation, but it must be an even number. The sprocket should be filled with lubricating oil in time during work. When the machine is stored for a long time, the sprocket should be removed and cleaned with kerosene or diesel oil, and then coated with oil or butter and stored in a dry place.
