23:11. Replacement of the bearing of a back nave
Prevention
For removal of the bearing of a back nave it is necessary to use a hydraulic press and tubular mandrels of the corresponding diameter. In the absence of a press it is possible to use big table vises. Internal rings of the bearing are pressed on the nave plug. If at removal of the bearing its internal ring remains on the nave plug, for removal of this ring it is necessary to use a stripper.
