8.1.4. Removal and transmission installation


The arrangement scheme карданных shaft and components of system of release of the fulfilled gases


Removal

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Remove from the top part of transmission the gauge of position of a cranked shaft (OBD), — try not to damage gauge edge.
  3. Remove forward and back sections of system of release of the fulfilled gases (the arrangement Scheme карданных shaft and components of system of release of the fulfilled gases see an illustration).
  4. Remove from assemblage АТ зарядную tube ATF and a tube of cooler ATF, — at once закупорьте the open ends of lines and unions in order to avoid hit in dirt system.
  5. Remove карданные shaft (the arrangement Scheme карданных shaft and components of system of release of the fulfilled gases see an illustration).
  6. Remove приводную draught from a distributing box. Right after removals back карданного a shaft закупорьте сальниковое an aperture, try not to damage an epiploon and шлицы a sliding collar карданного a shaft.
  7. Remove from transmission a cable of a drive of switchings.
  8. Disconnect electroconducting from transmission and gauge VSS.
  9. Remove a starter.
  10. Remove кницу and a back plate of fastening of transmission to the engine.
  11. Turn out bolts of fastening of the hydrotransformer to приводному to a disk, — for the purpose of maintenance of serial access to bolts turn a cranked shaft.
  1. Prop up АТ special трансмиссионным a jack.
  1. Disconnect from transmission a back support of a suspension bracket of the power unit.
  2. Turn out bolts of fastening of transmission to the engine.
  3. Lower transmission in gathering with a distributing box and take it from under the car.


Installation

 PERFORMANCE ORDER

  1. With the help циферблатного a measuring instrument плунжерного type estimate size of lateral palpation приводного a disk. Compare results of measurement to requirements of Specifications (Transmissionnaja a line see), in case of need make disk replacement in gathering with a gear wreath.
  1. Before hydrotransformer connection to приводному to a disk check up depth of landing of the last "And", — the minimum admissible value makes 26.0 mm.
  1. Establish the hydrotransformer, then some times turn a cranked shaft for check of freedom of rotation of transmission.
  1. Tighten bolts of fastening of transmission to the engine with demanded effort.

    Length of bolts (l), mm:
    1 — 47.5
    2 — 58.0
    3 — 25.0
    Fastening bolts кницы to the engine — 20.0

  1. Installation of the remained components is made in an order, the return to an order of their dismantle.
  2. In summary check up level ATF (Routine maintenance see the Head) and make sure of serviceability of functioning of the lever of the selector.
  3. Squeeze out a lay brake and start the engine on single turns. Serially switch the selector lever in each of working positions (N> D> 2> 1> R), — at each switching the lever should twitch slightly.
  4. Make car trial runs.
