Dismantling and assembly of differential


13 — the differential Case
14 — Spherical laying
15 — Satellites
16 — the Finger

17 — Conic gear wheels of power shafts
18 — Persistent laying
19 — the Roller finger



1. Fix the case of differential 13.

2. Beat out a roller finger 19 and a finger of differential 16 of the case of differential 13 by means of a punch.

3. Remove satellites 15 with spherical laying 14 and conic gear wheels of power shafts 17 with persistent laying 18.

4. Check each element for lack of wear.



1. Insert a pin 046 into an opening in the differential case.

2. Install both conic gear wheels of power shafts 17 with persistent laying 18 on a pin in the differential case.

3. Install both satellites 15c by spherical laying 14 and turn them by means of a pin 046.

4. Instead of a finger of differential insert a pin 021 into the differential case for fixing of conic gear wheels of power shafts and satellites.



1. Check the moment of rotation of differential. It has to make 5-30 H • m.
2. Establish a finger of differential 16 and a roller finger 19.
3. Take the differential case from a vice.
