1. The sprocket ought to be installed on the shaft without skew and swing. In the same transmission assembly, the finish faces of the two sprockets should be in the same plane. When the guts distance of the sprocket can be less than 0.5 m, the deviation is 1 mm. When the guts distance of the sprocket is definitely 0.5 m or even more, the deviation is 2 mm. Nevertheless, the medial side phenomenon of the friction sprocket tooth isn’t allowed, and if the two-wheel knitting is usually too big, the chain is easily broken and the wear is accelerated. Care must be taken up to check and adapt the offset when changing the sprocket.
2. The tightness of the lifting chain should be suitable, too tight to increase power consumption, the bearing is simple to wear; as well loose 
chain is easy to jump and unchain. The tightness of the chain is certainly: lifting or pressing from the middle of the chain, the center distance of the two sprockets is about 2% – 3%.
3. The brand new lifting chain is too long or stretched after use. It is difficult to adjust. The chain links could be taken out, but they should be actually. The links should go through the trunk of the chain, the locking tabs are inserted outside, and the starting of the locking tabs should be in the opposite direction of rotation.
4. Following the sprocket wears seriously, the brand new sprocket and the brand new chain should be replaced simultaneously to make sure good meshing. It is not feasible to replace a fresh chain or a new sprocket alone. Failure to take action may result in poor engagement to accelerate the put on of the brand new or new sprocket. After the sprocket tooth surface wears to a particular extent, it should be turned over in time (refer to the sprocket utilized for the adjustable surface area). To extend the use of time.
5. The old lifting chain can not be mixed with some new chains, or else it will easily cause impact in the transmission and break the chain.
6. Lift the chain to remember to fill the lubricant with time. The Motorcycle chain lubricating essential oil must enter the mating clearance between the roller and the inner sleeve to improve working conditions to lessen wear.
