PERFORMANCE ORDER
1. Remove клиновой a ridge belt.
2. Unscrew the refrigerating compressor (arrows) and hang it together with the connected wires sideways on a body.
3. Cars with height adjustment: unscrew oil hoses of the delivery oil pump (arrow). If the double pump is established, disconnect маслопроводы from the pump.
4. Suck away a special syringe hydraulic oil from the tank of the amplifier of a steering. Unscrew and curtail hoses. The flowed out liquid collect a rag.
5. An automatic transmission: clips for hoses draw маслопроводы маслоохладителя.
6. Unscrew маслопроводы (arrows) air маслоохладителя.
7. A mechanical transmission: preliminary having wrung out lock clips, remove rods of plugs from box handles передач.*
8. Unscrew hydraulic hoses of the gauge of coupling (arrow).*
9. An automatic transmission: disconnect from a transmission the lever mechanism of switching and remove an element of connection of wires of switches of blocking of start and a tail light (S 16/1). Disconnect an element of connection of wires Kickdown - the magnetic valve on the right party of a box передач.*
10. If is available, unscrew the tachometric inductive gauge (arrow) and unscrew two bottom bolts of a starter. Connecting wire put aside. If the engine acts in film without a transmission, remove стартер.*
11. Unscrew the gauge of number of turns (L3).*
12. Unscrew "a weight" wire between a starter and a body.
13. If the engine separates from a transmission, remove a starter.
14. Unscrew a lateral support газовыпускного devices from a box передач.*
