Remove the front should clarify the relationship between the bearing and the associated parts: careful observation associated with the relationship between the position of the bearing member is located, the installation process and analysis methods, and to develop methods and procedures for disassembly.
2. Can not dismantle as much as possible without removal: separation of bearings, the inner and outer rings are usually interference fit, in order to ensure its fitting accuracy, shorten repairman period, can not be demolished try not to split.
3. Removal of using scientific methods:
(1) Remove the journal, should be urged to the inner ring, remove the bearing seat of the bearing inner race should be urged.
(2) Remove the bearing inner or outer ring, the force should be balanced, uniform, not skewed, to prevent stuck.
