Dismantling and assembly of differential with automatic blocking


The differential with automatic blocking is shown on an illustration: And — the Block of frictional disks with the conducted gear wheel with a diameter of 185 mm.

Dismantling

Take a roller finger 19 and a finger of differential 16 by means of a drift from the case of differential 13

To all illustrations:
13 — the differential Case
14 — the Spherical washer
15 — Satellites
16 — a differential Finger
17 — Gear wheels of the drive of power shafts

19 — the Roller finger
22 — the Frictional disk with a slip on the one hand
23, 23a — Frictional disks without slips
24 — Frictional disks with slips on both sides


 PERFORMANCE ORDER

1. Fix the case of differential 13.

2. Take a roller finger 19 and a finger of differential 16 by means of a drift from the case of differential 13.

3. Establish drifts 046 in gear wheels of the drive of power shafts 17.

4. Turn satellites 15 with spherical washers 14 towards an opening and remove them.

5. At first remove the right gear wheel of the drive of a power shaft 17 (it is shown in the established provision) with frictional disks.

6. Remove the left gear wheel of the drive of a power shaft 17 (from the conducted gear wheel) with frictional disks.


Assembly

Fix frictional disks in the correct order on both gear wheels of the drive of power shafts 17

17 — the Gear wheel of the drive of a power shaft
22 — the Frictional disk with a slip on the one hand

23, 23a — Frictional disks without slips
24 — Frictional disks with slips on both sides


 PERFORMANCE ORDER

1. Fix frictional disks in the correct order on both gear wheels of the drive of power shafts 17 and carefully grease frictional disks 22 and the 24th universal gipoidny transmission liquid.

2. At first establish the left gear wheel of the drive of a power shaft (from the conducted gear wheel) with frictional disks, then establish the right gear wheel of the drive of a power shaft 17s by frictional disks and establish a drift 046 having paid attention that frictional disks without slips have ears (shooters).

3. Install satellites 15 with spherical washers 14, using a drift 046, roll them until they are not established in the differential case.

4. Install a differential finger by means of a drift in satellites and spherical washers.
5. Check the moment of friction of differential. It has to make 80-160 N · m.
6. Establish a finger of differential 16 and a roller finger 19.
7. Take differential from a vice.
