9.3.8. Removal, installation and adjustment of executive cylinders and components of the mechanism of the drive of blocking of interwheel differentials

Peredny Bridge

Executive cylinder

Details of installation of the executive cylinder (1) of the drive of blocking of differential of the forward bridge

Adjustment of the executive cylinder (1) of the drive of blocking of differential of the forward bridge

1 — the Executive cylinder

2 — pressure Sensor switch

 PERFORMANCE ORDER

  1. Disconnect from assembly of the executive cylinder (1) the hydraulic line, - at once to a zakuporta the open ends of the line and nipple knot for the purpose of prevention of an effluence of brake fluid.
  2. Release a cap nut and disconnect an electrical wiring.
  3. Mark adjusting position of the cylinder (1) concerning a bridge sleeve.
  4. Turn out fixing screws and remove the cylinder (1).
  5. Install the cylinder on the regular place according to the landing tags put in the course of dismantle.
  6. If dismantling of the cylinder was made (see the Section Dismantling and assembly of the executive cylinder of the drive of blocking of differential) or replacement of components of the mechanism of blocking of differential (see below), make the corresponding adjustment (see further).
  7. Screw the sensor switch of pressure (2) in the cylinder (1) and tighten it with initial effort.
  8. Fix the cylinder (1) on a bridge case so that there was a possibility of correction of its provision.
  9. Activate the cylinder and fix the cam coupling.
  10. Correct position of the cylinder so that it rested against the coupling, - at an otpuskaniye the cylinder should not be displaced under the influence of the effort developed by an internal spring back.
  11. Tighten the cylinder with the required effort.
  12. Finally tighten pressure sensor switch.
  13. Restore initial connection of an electrical wiring and the hydraulic line.
  14. In conclusion make removal of air from a hydraulic path of the drive of blocking of differential (see the Section Removal of Air from a hydraulic path of the drive of blocking of differentials).

Blocking inclusion mechanism

Details of installation of components of the mechanism of blocking of differential of the forward bridge

1 — the Executive cylinder
2 — a bridge case Sleeve
3 — the Hinged casing

4 — Assembly of differential with the conducted gear wheel of the main transfer
5 — the switching mechanism Coupling
6 — a switching mechanism Tube

 PERFORMANCE ORDER

  1. Remove the executive cylinder (1) (see above).
  2. Remove a hinged casing (3) assembled with a power shaft (see the Section Removal and installation of power shafts of the forward bridge).
  3. Remove differential assembled with the conducted gear wheel of the main transfer (4) (see the Section Removal and installation of assemblies of interwheel differentials with the conducted gear wheels of the main transfers).
  4. Remove the coupling of the mechanism of switching (5), having slightly extended it assembled with a tube (6) then having unhooked.
  5. Pick up the phone (6).
  6. Remove polyamide rings from a tube (6).
  7. Carefully wipe the removed components the failed components replace.
  8. Establish polyamide rings, previously having greased their rubbing surfaces.
  9. Establish a tube of the mechanism of switching (6).
  10. Pick up the coupling (5) and push together with a tube before emergence of an adjusting nest in a bridge case sleeve opening (see an illustration below).
  11. Establish assembly of differential (4).
  12. Establish a hinged casing (3) assembled with a power shaft (see the Section Removal and installation of power shafts forward the bridge).
  13. Install the executive cylinder (see above).

Zadny Bridge

Executive cylinder

Details of installation of the executive cylinder of the drive of blocking of differential of the back bridge

1 — Sealing laying
2 — pressure Sensor switch
3 — the Executive cylinder

4 — the Hydraulic line
5 — the Cap nut
6 — the Adjusting nest

Adjustment of the executive cylinder (1) of the drive of blocking of differential of the back bridge


 PERFORMANCE ORDER

  1. Disconnect from assembly of the executive cylinder (3) the hydraulic line (4), - at once to a zakuporta the open ends of the line and nipple knot for the purpose of prevention of an effluence of brake fluid.
  2. Release a cap nut (5) and disconnect an electrical wiring.
  3. Mark adjusting position of the cylinder (3) concerning a bridge sleeve.
  4. Turn out fixing screws and remove the cylinder (3).
  5. Level an adjusting nest (6) of the coupling of switching on the center of an aperture in a case sleeve.
  6. Install the cylinder (3) on the regular place according to the landing tags put in the course of dismantle, - do not forget to replace sealing laying (1). Screw fixing bolts, - the lever of switching has to get to an adjusting nest of a tube while there has to be a possibility of correction of the provision of the cylinder.
  7. Having given hydraulic or pneumatic pressure, force the cylinder to work, then, feats, rest it against the cam coupling (shooter), - at the same time turn half shafts before activation of blocking of differential.
  8. Tighten fixing bolts with the required effort, then dump hydraulic/pneumatic pressure.
  9. Having rotated half shafts make sure of serviceability of blocking of differential.
  10. Restore initial connection of an electrical wiring and the hydraulic line.
  11. In conclusion make removal of air from a hydraulic path of the drive of blocking of differential (see the Section Removal of Air from a hydraulic path of the drive of blocking of differentials).

Blocking inclusion mechanism

Details of installation of components of the mechanism of blocking of differential of the forward bridge

1 — the Executive cylinder
2 — a bridge case Sleeve
3 — the Polyamide ring
4 — Assembly of differential with the conducted gear wheel of the main transfer

5 — the switching mechanism Coupling
6 — a switching mechanism Tube

The order of implementation of the procedure is similar described above for the forward bridge adjusted for lack of a hinged casing.
