Removal and installation of a back axis
Removal
Remove a back brake drum, колодки and a basic brake disk.
Remove a cross-section beam.
Disconnect a back axis and the longitudinal lever in a following order:

Fig. 5.51. An arrangement of a rack (1) for support of a back axis and a nut (3) and a bolt (2) fastenings of the shock-absorber




- Support a back axis by means of racks 1 (fig. 5.51);
- ослабьте a nut of 3 fastenings of the shock-absorber to a body arm;
