If the bearing of the upper support of the telescopic strut is worn, corroded or damaged, it is replaced. To do this, the support body is flared, and then the bearing is pressed out of the support body under pressure using a mandrel 67.7853.9588, using a stand 67.7822.9530. Before pressing in a new bearing, make sure that there are no burrs or burrs in the bearing seat. The detected irregularities are eliminated with a fine-grained sandpaper.
Using a special mandrel, the bearing is pressed into the support body, after which the support body is pressed in four equally spaced places that were not previously deformed, using a special mandrel or a blunt chisel for this. After the housing has been compressed, the bearing must not move in the axial direction under a load of 600 kgf.
