Installation
Installation is carried out to the sequences, the return to removal, taking into account the following.
At installation of the engine it is necessary to replace with new samokontryashchiyesya of a nut and bolts which tightened a dovorachivaniye on a certain corner, and also sealing rings and laying.
At installation check existence of the aligning plugs defining interposition of the engine and transmission.
At connection of the engine with the transmission be careful – do not damage the sensor of frequency of rotation of the engine.
For fastening of the hydrotransformer to a drive plate it is necessary to use bolts of an original design.

Check correctness of installation of the hydrotransformer. If the distance between a basic surface for bolts of fastening of the hydrotransformer and a surface of a case makes 19 mm, so the hydrotransformer is installed correctly. At incorrectly installed hydrotransformer this distance makes about 22 mm (fig. 3.4-14), at the same time the leading part of the hydrotransformer and the pump of the automatic transmission collapse.
Install the engine into place and, having shaken it here and there, provide the correct arrangement on support.
Install the driveshaft.
