Connect the hydrotransformer from a transmission and establish a transmission assembled on the engine (fig. 3.97).

ATTENTION If the hydrotransformer at first to establish on the engine, at installation of a transmission the check point epiploon will be damaged. Therefore before assembly of the power unit always establish the hydrotransformer from a transmission.

Establish a cable of management of AKPP and adjust it the following in an order given below.

Move the lever of the AKPP selector and the switch of blocking of a starter (the AKPP selector switch) on a transmission to the situation "N", then connect a cable of management of AKPP.

After connection of a cable of management of AKPP to intermediate fastening on an arm of a support of a transmission, reliably fix a cable a clamp.

Turn of an adjusting nut adjust the provision of a cable of management of AKPP on the switch of blocking of a starter (the AKPP selector switch) so that there was no free wheeling of a cable. Then check that the lever of the AKPP selector is switched smoothly.

Visually check correctness of adjustment of a cable of management of AKPP.

Installation of other details is made as it should be, the return to removal.
