18. Remove a basic arm of a soaking up collector.
19. Remove a reception pipe of the muffler.
Inzhektornye engines with direct injection of fuel
20. On инжекторных engines with direct injection of fuel execute following actions remove an air line of the air filter.
21. Execute actions on декомпрессии fuel system, disconnect from the chamber throttle заслонки a hose of giving of fuel and a return fuel hose (all apertures muffle to exclude losses of fuel and dirt hit).
22. Disconnect a cable of a drive throttle заслонки.
23. Disconnect from the chamber throttle заслонки, a soaking up collector and other details conducting sockets. Take conducting aside from a collector and a head of cylinders that it did not interfere with engine removal.
24. Disconnect a vacuum hose of the amplifier of brakes, a hose of a cooling liquid, vacuum hoses of valves (1) and ventilation hoses картера from a soaking up collector (2 – bolts of connection with weight).
25. Remove a basic arm of a soaking up collector.
26. Ослабьте collars also disconnect from the engine hoses of a heater and other hoses of system of cooling, preliminary having marked an initial arrangement of each hose.
27. On the cars equipped with the conditioner, turn away bolts of fastening of the compressor and take the compressor aside. Tie up the compressor to a body so that its weight was not perceived by tubes and hoses of a highway of the conditioner. Hoses from the conditioner not to disconnect.
28. Being guided by the description (subsection 7.7.4 see), disconnect all sockets of conducting from the distributor of ignition, the coil of ignition and a transistor power unit. Release a sleeve of conducting from clips on a head of cylinders and take aside. Turn away bolts and remove all wires of connection with weight on a head of cylinders and on a soaking up collector.
29. Turn away bolts and remove all wires of connection with weight on a head of cylinders
30. Remove semiaxes in gathering with карданными hinges (subsection 10.2 see).
31. Disconnect from a check point a cable of a drive of coupling (subsection 8.3 see).
32. Disconnect from a check point a rod of inclusion of transfers (1), draughts of a gear change (2), a cable of a speedometer and conducting sockets.
33. Bring таль the lift and fix on arms of a head of cylinders, pull таль that it had been apprehended weight of the power unit.
34. A paint or a marker put labels of an arrangement of a coupling bolt (is specified by an arrow) on an arm of a forward support of the power unit that at assemblage to establish this bolt in former position.
35. Ослабьте an inhaling also turn away a nut of a coupling bolt (it is specified by an arrow), get a bolt from a support. Turn away a nut and get a coupling bolt of a back support of the power unit.
36. Turn away four bolts of fastening of the central longeron, remove a longeron, having got it from under the power unit.
37. Turn away a nut and get a coupling bolt of the right support of the power unit, then turn away bolts of fastening of a support and get a support from a motor compartment.
38. If landing of the rubber pillows established on both parties of an arm of a support from outside of a body remove pillows is weakened.
39. Turn on and get a coupling bolt of the left support of the power unit. Then turn away three bolts of fastening of a support to a check point and displace a support aside. If landing of the rubber pillows established on both parties of an arm of a support remove pillows is weakened.
40. Be once again convinced that all details, wires and hoses which can prevent dismantle of the power unit, are disconnected or removed. Be convinced also that at unit dismantle will not be сдеформированы or other details of the car (for example draught and a rod of management of a check point) are damaged.
41. If there is a low cart drive it under the engine that will facilitate extraction of the removed unit from under the car. Lower the power unit, watching to damaging or to hook on details being nearby. This operation is expedient for carrying out with the assistant, as it is required to incline a little the unit not to touch the body panel. At engine lowering be extremely cautious.
