9.3.7. Removal and installation of the leading gear wheels of the main transfers

Peredny Bridge

Details of installation of the leading gear wheel of the main transfer of the forward bridge

1 — Assembly of differential with the conducted gear wheel of the main transfer
2 — the Nut
3 — the Connecting flange
4 — the Leading gear wheel
5 — the Conical roller bearing

6 — the Epiploon
7 — the External holder of the bearing
8 — the Compression ring
9 — the Adjusting washer

Scheme of installation of a basic crossing point (3)


 PERFORMANCE ORDER

  1. Remove assembly of forward interwheel differential with the conducted gear wheel of the main transfer (1) (see the Section Removal and installation of assemblies of interwheel differentials with the conducted gear wheels of the main transfers).
  2. Remove epiploons (6) the conducting gear wheels (4) of the main transfer (see the Section Replacement of Epiploons of the Leading Gear Wheels of the Main Transfers).
  3. Приболтив to a reducer case a basic crossing point (3), squeeze out the leading gear wheel (4) and, - in case of need, - develop openings in a crossing point under diameter of 11 ÷ 12 mm. In case of need make dismantling of the leading gear wheel.
  4. Remove the conical roller bearing (5) and a compression ring (8).
  5. Carefully wipe the removed components and visually estimate their condition. Replace the damaged details.
  6. Establish into place the leading gear wheel (4), previously having filled in it a pin.
  7. Establish the NEW compression ring (8).
  8. By means of a suitable mandrel put into place the conical roller bearing (5).
  9. Establish on a gear wheel (4) NEW epiploons (6).
  10. By means of a special dynamometer (001 589 49 21 00) measure the gear wheel resistance to a provorachivaniye, - in case of need tighten a nut of a connecting flange.

If the nut was tightened with excessive effort, it is necessary to replace a compression ring (8)!

  1. Establish into place assembly of differential with the conducted gear wheel (1) (see the Section Removal and installation of assemblies of interwheel differentials with the conducted gear wheels of the main transfers).
  2. Check concentricity of landing of a connecting flange, in case of need make the corresponding adjustment (see the Section Check of Concentricity of Landing of Connecting Flanges of the Leading Gear Wheels of the Main Transfers).

Details of installation of the leading gear wheel of the main transfer of the back bridge

1 — a differential Box with the conducted gear wheel of the main transfer
2 — the Nut
4 — the Leading gear wheel
5 — the Internal conical roller bearing
6 — Epiploons

7 — the External holder of the internal bearing
8 — the Compression ring
9 — the Adjusting washer
10 — the Connecting flange
12 — the External conical roller bearing

 PERFORMANCE ORDER

  1. Remove assembly of back interwheel differential with the conducted gear wheel of the main transfer (1) (see the Section Removal and installation of assemblies of interwheel differentials with the conducted gear wheels of the main transfers).
  2. Remove from a gear wheel (4) a connecting flange (10).
  3. Remove epiploons (6) the conducting gear wheels (4) of the main transfer (see the Section Replacement of Epiploons of the Leading Gear Wheels of the Main Transfers).
  4. Приболтив to a reducer case a basic crossing point (3), squeeze out the leading gear wheel (4) assembled with a compression ring (8), - in case of need develop openings in a crossing point under diameter of 11 ÷ 12 mm. In case of need make dismantling of the leading gear wheel.
  5. Carefully wipe the removed components and visually estimate their condition. Replace the damaged details.
  6. Put on the leading gear wheel (4) the NEW compression ring (8).
  7. Fill the leading gear wheel (4) in a reducer case, previously having put in it a pin.
  8. By means of a suitable mandrel put the external conical roller bearing (12).
  9. Establish NEW epiploons (6) (see the Section Replacement of Epiploons of the Leading Gear Wheels of the Main Transfers).
  10. Attach to a gear wheel (4) a connecting flange (10) (see the Section Check of Concentricity of Landing of Connecting Flanges of the Leading Gear Wheels of the Main Transfers).
  11. Measure the gear wheel resistance to a provorachivaniye (see above paragraph 10 in subsection Peredny Bridge) and concentricity of its landing (see the Section Check of Concentricity of Landing of Connecting Flanges of the Leading Gear Wheels of the Main Transfers), - in case of need make the corresponding adjustments.
  12. Establish into place assembly of differential with the conducted gear wheel (1) (see the Section Removal and installation of assemblies of interwheel differentials with the conducted gear wheels of the main transfers).
  13. By assessment of spots of contact check correctness of input of gear wheels of the main transfer to gearing, - in case of need make the corresponding adjustment (see the Section Check of Concentricity of Landing of Connecting Flanges of the Leading Gear Wheels of the Main Transfers).
