Removal and engine installation

The description of removal of the engine for all types of engines would leave far for a framework of this management. Here only some essential points concerning this subject are given.

  • The engine is taken out up without a transmission. For this purpose it is required to you полиспаст (таль) which you can strongly suspend at sufficient height. It is even better, if you have an assistant who already have experience.
  • Before the beginning actually works on removal of the engine it is necessary to remove all stirring parts of the car: cowl, bottom protection of the engine, case of the air filter, storage battery and if necessary radiator.
  • As in the Audi 80 car the large quantity of electric wires and vacuum pipelines is established, you should mark out first of all them everything in summary to establish them everything on the right place.
  • Before shutdown of the storage battery you should be convinced available at you a number protective code of the anticreeping coding of an autoradio tape recorder.
  • The storage battery should be disconnected only at the switched-off ignition, differently it is possible to damage control units.
  • Before it is final отфланцовывать the engine, it is necessary to bring under a transmission a support from below or slightly to raise it together with even built-in engine. In a workshop for this purpose apply the special tool which rests against the region of fastening of a wing of the car.
  • The engine is supplied with pendant eyes into which it is possible to insert the tool for lifting. Watch careful fixing of a cable.

Illustrations show two important steps at engine removal (the 6-cylinder engine is represented): in a workshop the engine acts in film by means of such adaptation for engine lifting. Only for this purpose the engine has fixing eyes into which, of course, it is possible to insert and chains or ropes. The image on the right shows the so-called basic device (1) which here is integrated with the holder of a transmission (2). Sense in giving a support to a transmission which otherwise at the removed engine would settle down. The same effect can achieve if to bring under a transmission a support from below.
