Installation 1. Check the pulley groove to ensure that there are no scars or sharp edges, and all dimensions meet the standard; 2. Clean the surface of all parts, such as the hub hole, taper sleeve, bolt hole, etc.Put the cone into the pulley and align all the screw holes. 3. Apply oil to the screw (TB 1008-TB 3030) and thread (TB 3525-TB 5050) and screw into the mounting hole, but do not tighten it temporarily. 4. Clean the surface of the drive shaft, push the pulley with the taper sleeve to the predetermined position on the shaft, and check whether the V-belt is aligned. 5. When using the keyway, you must first insert it into the hub, and there must be a certain tolerance between the keyway and the hole hub. 6. Use a hexagonal wrench that meets DIN911 standards to alternately tighten each bolt in each mounting hole gradually and evenly until the torque shown in the following table is reached. 7. After a short period of operation (0.5 to 1 hour), check the tightening torque of the bolts, and re-tighten if necessary. 8. To prevent the intrusion of foreign matter, fill the connecting hole of the hole with grease.Disassembly 1. Loosen all bolts, take out one or two bolts according to the number of disassembly holes, lubricate the bolt pattern and bolt tip with oil, and insert the bolt into the disassembly hole shown in the figure below. 2. Tighten the bolts alternately until the taper sleeve and pulley are loosened. 3. Take out the taper sleeve and pulley from the shaft.
