1. The last cleaning of the assembly must use petrol to ensure that the components are clean and dry to ensure that the mating surface is tightly coupled with no grease and that there is sufficient friction.
2. The assembling of hexagon bolts before the assembly of the use of gasoline cleaning and drying, not in the bolt or screw holes in lubricating oil or grease, to ensure that the bolt after fastening enough friction self-locking ability.
3. Three internal hexagon bolts will be installed in place when tightening, to ensure that the cone sleeve by the uniform axial force, to ensure that the pulley and cone sleeve coaxial positioning good.
4. Pre-installation inspection and measurement of the six-angle bolt length of the assembly to ensure that the assembly bolt after fastening can withstand the cone sleeve blind hole bottom, to ensure that the cone fit tightly, and to ensure that the bolt by the bottom of the blind hole reverse thrust, the same as the principle of double nuts to prevent loose
5. Belt pulley fastening after the pull line check and adjust the main, from the moving pulley relative position to ensure that the two wheels in the same plane and belt tensioning appropriate.
6. Belt pulley cover should be intact and firmly installed to ensure that the operation of the belt break or pulley loose exit into a major safety accident.
7. Cone cover is easy to wear parts, after a long time running, the inner hole and chain groove may be damaged, each assembly should be inspected before the defect should be replaced in a timely manner.
