First, disassembly
1. First loosen the locking screw on the eccentric sleeve of the bearing with an Allen key, then insert the small iron rod into the counterbore on the eccentric sleeve of the top cover, and loosen the eccentric sleeve against the direction of rotation of the shaft.
2. Loosen the bolts that secure the bearing housing. Remove the bearing from the shaft together with the housing. Note before removing the bearing housing at one end of the shaft. The bearing block bolts at the other end of the shaft should be loosened to prevent the bearings at both ends from being damaged by each other.
Second, the installation
1. Before installing the bearing on the shaft, the bearing pin of the bearing sleeve must be unplugged, and the surface of the journal should be smoothed and cleaned, and the oil is rust-proof and lubricated at the journal (allowing the bearing to rotate slightly on the shaft).
2. Apply lubricant to the bearing seat and bearing mating surface, and install the bearing into the bearing housing. Then the assembled bearing is placed on the shaft together with the bearing housing. Push to the desired location for installation.
3. The bolts of the fixed bearing housing should not be tightened first, so that the bearing housing can rotate in the bearing housing. Also install the other end bearing and seat on the same shaft, turn the shaft a few turns, and let the bearing itself automatically find the position. Then fasten the bearing block bolts.
4. Install the eccentric sleeve. First, eccentric sleeve is placed on the eccentric step of the inner sleeve of the bearing, and the shaft is tightened by hand in the direction of rotation. Then insert or hold the small iron rod against the counterbore on the eccentric sleeve. 1. Use a hammer to strike a small iron rod in the direction of rotation of the shaft. Install the eccentric sleeve securely and finally lock the socket head cap screws on the eccentric sleeve.
