Back support of transmission and intensifying beam

 A–back support of transmission

B–intensifying beam

Removal and installation

1. Disconnect the battery from weight.
2. Disconnect a kick-down-cable and deduce from an arm on a soaking-up collector.
3. On the M10 engine uncover the distributor.
4. Lift the car.
5. Remove exhaust pipes.
6. Disconnect draft or a cable.
7. Remove the driveshaft (see subsection 9.10).
8. Merge transmission liquid. Disconnect tubes of a cooler of liquid and a refueling branch pipe.
9. On transmission 3НР22 in the lower part of a case of the hydrotransformer uncover, and on other check points remove an intensifying plate and the buffer limiter: dark shooters specified bolts which should be turned on.
10. Through a window in a case unscrew bolts of fastening of the hydrotransformer to a leading disk (3 or 4 bolts depending on transmission type), turning the crankshaft. To unscrew all bolts, turn the hydrotransformer.
11. On cars with system of injection of Motronic remove sensors of rotation and a crankshaft angle of rotation (see subsection
12. On cars with transmission 4НР22ЕН disconnect the socket on the left side of transmission.
13. Substitute under transmission the cart with a jack, prop up the pallet through a board and unscrew bolts of fastening of support and an intensifying beam to a body. Lower the power unit on a cross-piece of a forward suspension bracket.
14. Unscrew bolts of fastening of transmission to the engine.
15. Remove a lateral lattice in a case of the hydrotransformer (2) and separate transmission, holding the hydrotransformer so that it remained on transmission (1 – a leading disk). In process of removal of transmission by a screw-driver make effort in the arrow direction.
16. If transmission changes, rearrange the hydrotransformer on the new unit. For removal screw 2 long bolts in openings of the hydrotransformer and evenly wrapping them. The order of installation is described below.

17. Installation is carried out upside-down. Before assembly blow and wash out pure transmission liquid of a tube of a cooler. On transmission 4НР22ЕН the socket attach so that labels coincided. Adjust all cables and draft of the selector.
