Dismantling and assembly of differential with automatic blocking

Differential with automatic blocking

Differential with automatic blocking

A — the Block of frictional disks with the conducted gear wheel with a diameter of 185 mm
In — the Block of frictional disks with the conducted gear wheel with a diameter of 210 mm

Dismantling

By means of a drift take a roller finger (19) and a finger of differential (16) from the case of differential (13)

14 — the Spherical washer
15 — Satellites
17 — Gear wheels of the drive of power shafts

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 (24) 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 (17) with frictional disks and establish a drift (046) having paid attention that frictional disks without slips have ears.
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 Nanometers.
6. Establish a finger of differential (16) and a roller finger (19).
7. Take differential from a vice.
