9.3.19. Dismantling and assembly of interwheel differentials

Peredny Bridge

Design of interwheel differential of the forward bridge

1 — the Conducted gear wheel of the main transfer
2 — Conical roller bearings
3 — a differential Box
4 — Side gear wheels

5 — Krestovina
6 — Satellites
7 — Spherical washers

 PERFORMANCE ORDER

  1. Remove differential assembled with the conducted gear wheel of the main transfer (see the Section Removal and installation of assemblies of interwheel differentials with the conducted gear wheels of the main transfers).
  2. Turn out fixing bolts and remove the conducted gear wheel (1).
  3. By means of a suitable stripper dismantle conical roller bearings (2).
  4. Uncover a box of differential (3), - mark the provision of spherical washers, gear wheels and a crosspiece from each other and concerning a box. Also mark the provision of a cover concerning a box.
  5. Remove one of side gear wheels (4) with an adjusting washer.
  6. Take assembly of a crosspiece (5) with satellites (6).
  7. Remove satellites (6) with spherical washers (7).
  8. Remove the second side gear wheel (4).
  9. Carefully wipe the removed components, replace defective parts.
  10. Installation is made upside-down, - adjusting washers have to be developed by flutes to side gear wheels. Track correctness of combination of the adjusting tags put in the course of dismantle. Before installation of conic bearings check resistance side to a gear wheel to a provorachivaniye, - in case of need pick up replaceable adjusting washers.

Before a napressovka bearings should be warmed up to the temperature about 80 °C, - bearings have to be put end-to-end with differential gear wheels.

Zadny Bridge

Design of interwheel differential of the back bridge

1 — the Conducted gear wheel of the main transfer
2, 12 — Conical roller bearings
3 — a differential Box
4 — Side gear wheels
5 — Krestovina

6 — Satellites
7 — Spherical washers
8, 11 — Bolts
9 — Persistent washers
10 — the Cover

 PERFORMANCE ORDER

  1. Remove differential assembled with the conducted gear wheel of the main transfer (see the Section Removal and installation of assemblies of interwheel differentials with the conducted gear wheels of the main transfers).
  2. By means of a suitable stripper dismantle the conical roller bearing (2) (from the conducted gear wheel).
  3. Turn out fixing bolts and remove from a box (3) the conducted gear wheel (1).
  4. By means of a suitable stripper dismantle the conical roller bearing (12) (from a box).
  5. Previously having marked adjusting situation, separate from a box (3) a cover (10).
  6. Remove the first side gear wheel (4) with a persistent washer (9).
  7. Take a crosspiece (5) with satellites (6) and spherical washers (7).
  8. Take the second side gear wheel (4) with a washer (9).
  9. Carefully wipe the removed components, replace defective parts.
  10. Installation is made upside-down, - adjusting washers have to be developed by flutes to side gear wheels. Track correctness of combination of the adjusting tags put in the course of dismantle. Before installation of conic bearings check the differential resistance to a provorachivaniye (before a napressovka conical bearings should be warmed up to the temperature about 80 °C, - bearings have to be put end-to-end with differential gear wheels).

Thinner adjusting washer has to be established from the conducted gear wheel for the purpose of providing a sufficient side play of gearing.
