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) from the case of differential (13) by means of a drift.

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 (address an accompanying illustration).

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 (15) with 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 the 5-30th.
2. Establish a finger of differential (16) and a roller finger (19).
3. Take the differential case from a vice.
