9.3.5. Check of concentricity of landing of connecting flanges of the leading gear wheels of the main transfers

At each removal of a connecting flange measurement of resistance to rotation of the respective bridge in collecting has to be performed (without wheels), - brakes have to be released.


Check of concentricity of landing of a connecting flange (1) of the leading gear wheel of the main transfer

Details of installation of a connecting flange

1 — the Connecting flange
2 — Flantsovannaya a nut


 PERFORMANCE ORDER

  1. Disconnect the driveshaft from a flange (1), take him aside and tie up a wire to a car frame, - the order of implementation of the procedure is similar described in the Section Detachment and connection of driveshafts on the transfer case for connecting flanges of the transfer case.
  2. Check is made by means of the dial measuring instrument of plunger type (DTI) and a special transitional flange (460 589 01 23 00).
  3. Connect a transitional flange to connecting (1).
  4. Fix a measuring instrument bed on a bridge case so that its plunger was pressed to a measuring surface of a forward pin of a transitional flange.
  5. Nullify the device and make the required measurement, having turned the main transfer on one whole revolution. Compare result of measurement to requirements of Specifications.

Peredny Bridge

At identification of a side play of a flange of the main transfer of the forward bridge replace a flange.

In order to avoid damage of bearings do not force down a flange the hammer at all, - in case of need use a special stripper (460 589 02 33 00)! The Flantsovanny nut is subject to replacement without fail!

Zadny Bridge

 PERFORMANCE ORDER

  1. If the side play of a flange of the back bridge exceeds extreme admissible value, unblock and release a flantsovanny nut (2) and remove a flange, previously having marked the provision of a nut and flange concerning a shaft of the leading gear wheel.

In order to avoid damage of bearings do not force down a flange the hammer at all, - in case of need use a special stripper (460 589 02 33 00)!

  1. Estimate a flange condition, in case of need make its replacement.
  2. If need for replacement because of identification of damages is absent, develop a flange on 180 ° clockwise, establish into place, and repeat check. Further, in case of need the flange can be developed two more times (on 90 ° and once again on 180 °). If it is not possible to achieve demanded result by deployment of a flange, make its replacement.
  3. Track that the flantsovanny nut (at refusal of its replacement) was tightened before combination of the landing tags put in the course of dismantle.

Both bridges

 PERFORMANCE ORDER

  1. Connect into place the driveshaft and fix it NEW самоконтрящимися by nuts, having tightened the last with the required effort.
