Removal

PERFORMANCE ORDER
1. Release pressure from a power supply system.
2. Disconnect a wire of the minus plug of the accumulator.
3. Uncover the valvate mechanism.
4. Open a cap of the control socket of pressure of fuel and release the remained pressure.
5. Disconnect sockets of connection of all sensors and solenoids, and also wires of "weight" (are specified by shooters).
6. Disconnect all vacuum, water and air hoses.
7. Disconnect an accelerator rope.
8. Turn off three fixing bolts of the module of distribution (are specified by shooters) ignitions and remove it.
9. Turn off four fixing bolts of the case of a butterfly valve and remove laying.
10. Disconnect the remained hoses and wires and remove the case of a butterfly valve.

Installation
