NOTE
Dismantling carry out in an order specified in drawing 3.35. Procedures of removal of separate components of a case are given below in this section.


Removal of an epiploon of primary shaft
Fig. 3.36. Removal of an epiploon of primary shaft


Remove an epiploon of primary shaft, using a screw-driver (fig. 3.36).

Removal of the bearing of a secondary shaft
Fig. 3.37. Removal of the bearing of a secondary shaft


Remove together a holder of the bearing of a secondary shaft and a bell (fig. 3.37).
To disassemble a cylindrical pin, combine a groove for removal of a pin of a case of coupling with the provision of a cylindrical pin.

Scheme of dismantling of a cylindrical pin
Fig. 3.38. Scheme of dismantling of a cylindrical pin


Beat out a pin, using small beards with a thin sting (fig. 3.38).

Moving of a rod of management before removal
Fig. 3.39. Moving of a rod of management before removal


To remove a management rod, move it in the direction of the arrow shown in drawing 3.39.

Probitiye of an opening in a case cover
Fig. 3.40. Probitiye of an opening in a case cover


Using a screw-driver with a flat shliyets and a hammer, make an opening in a cover (fig. 3.40).

Extraction of a sealing cap
Fig. 3.41. Extraction of a sealing cap


Take out a sealing cap, having inserted a screw-driver with a flat shliyets into an opening from the interior of a case (fig. 3.41).

Removal of an epiploon of a rod of management
Fig. 3.42. Removal of an epiploon of a rod of management


Remove an epiploon of a rod of management, using a screw-driver (fig. 3.42).

Removal of an epiploon of differential
Fig. 3.43. Removal of an epiploon of differential


Remove a differential epiploon, using a screw-driver (fig. 3.43).

Removal external ring of the bearing of differential
Fig. 3.44. Removal external ring of the bearing of differential: 1–bearing holder


Before disassembling a holder of the bearing of differential remove an external ring of the bearing, using the special adaptation (fig. 3.44).

Removal of a cylindrical pin
Fig. 3.45. Removal of a cylindrical pin


To remove a shaft of the lever of a backing, at first, by means of flat-nose pliers remove a cylindrical pin (fig. 3.45).

Removal of a shaft of the lever of a backing
Fig. 3.46. Removal of a shaft of the lever of a backing


Protect a shaft of the lever of a backing rags and, using the same flat-nose pliers, remove a shaft (fig. 3.46).

Removal of a holder of the bearing of a case of the main transfer
Fig. 3.47. Removal of a holder of the bearing of a case of the main transfer: 1–bearing holder; 2–press


By means of the special adaptation remove a holder of the bearing of a case of the main transfer (fig. 3.47).
