Disassembly steps and precautions:
1. First loosen the locking screw on the eccentric sleeve of the bearing with an Allen wrench, then insert a small iron rod into the counterbore on the eccentric sleeve of the top cover, and loosen the eccentric sleeve against the rotation direction of the shaft.
2. Loosen the bolts that fix the bearing pedestal. Remove the bearing together with the bearing seat from the shaft. Pay attention to loosen the bolts of the bearing seat at the other end of the shaft before removing the bearing seat at one end of the shaft, so as to avoid damage to the bearings at both ends.
Installation steps and precautions:
1. Before installing the bearing on the shaft, the fixing pin of the bearing sleeve must be pulled out first, and the surface of the journal must be polished smooth and clean, and the journal shall be coated with oil for rust prevention and lubrication (the bearing is allowed to rotate slightly on the shaft).
2. Apply lubricating oil on the mating surface of the bearing pedestal and the bearing, and install the bearing into the bearing pedestal. Then put the assembled bearing and bearing seat on the shaft and push it to the required position for installation.
3. Do not tighten the bolts that fix the bearing seat first, and make the bearing sleeve rotate in the bearing seat. Similarly, install the bearing and seat at the other end of the same shaft, rotate the shaft for several revolutions, and let the bearing itself automatically align. Then tighten the bolts of the bearing seat.
4. Install eccentric sleeve. First put the eccentric sleeve on the eccentric step of the bearing inner sleeve and tighten it by hand in the direction of rotation of the shaft. Then insert or counter the small iron rod into the counterbore on the eccentric sleeve. Knock the small iron rod with a hammer in the direction of rotation of the shaft to make the eccentric sleeve installed firmly, and finally lock the hexagon socket screw on the eccentric sleeve.
