Pressing in of bushes
Design of the auxiliary ring, dependent on the bush
The bushes can be easily pressed into the housing bore. The bushes can be pressed in more easily if the bush backing or housing bore is lightly oiled. Outside diameter Do up to approx. 55 mm: ■ Pressing in flush using a mandrel without an auxiliary ring, Figure 1 ■ Pressing into a counterbore using a mandrel without an auxiliary ring, Figure 2 Outside diameter Do from approx. 55 mm: ■ Pressing in using a mandrel with an auxiliary ring, Figure 3, Design of the auxiliary ring, see table and Figure 3, page 32.
