5.14. Removal and installation of the engine

Remove the engine assembled with the transmission, lowering it from a motor compartment down. It is more convenient to remove the engine from the car installed on the elevator.
Before removal of the engine it is necessary to prepare a reliable support on which the engine has to stand steadily.

Good advice
Before a detachment of hoses and electric wires we recommend to mark them not to mix at assembly.

It will be required to you: keys "on 10", "on 13", "on 15", "on 17", screw-drivers, passatizh, nippers or a knife, таль or other lifting device, slings (a strong rope).
1. Remove a decorative casing of the engine (see. "Removal and installation of a decorative casing of the engine").
2. Reduce pressure in a power supply system if work is performed right after a trip (see. "Pressure decrease of fuel in a power supply system").
3. Disconnect a wire from the minus plug of the rechargeable battery.
4. For convenience of work remove the rechargeable battery (see. "Removal and installation of the rechargeable battery").
5. Remove an engine mudguard (see. "Removal and installation of a mudguard of the engine").
6. Merge cooling liquid (see. "Replacement of cooling liquid").
7. Remove the air filter (see. "Removal and installation of the air filter").
8. Disconnect from a head of the block, throttle knot and an inlet collector all hoses, pipelines and wires which disconnected before removal of a head of the block of cylinders for replacement of its laying, and also a cable of the drive of a butterfly valve together with its arm (see. "Replacement of laying of a head of the block of cylinders").
9. Disconnect blocks of plaits of wires from the sensor of speed, the sensor of provision of a bent shaft and the sensor of a detonation (see. "Sensors of a control system of the engine").
10. Disconnect wires from a starter (see. "Removal and installation of a starter") and the generator (see. "Removal and installation of the generator").
11. Disconnect a block of a plait of wires from the backing light switch on the transmission.
12. Separate blocks of plaits of wires of sensors of concentration of oxygen and take holders of their wires from openings of a heat-insulating guard of the steering mechanism (see. "Replacement of a katkollektor").
13. Disconnect holders of a motor plait of wires from an arm on the engine and take a plait aside.
14. Weaken an inhaling of collars …
15. … also disconnect from the thermostat everything hoses.
16. Weaken a collar inhaling …
17. … also disconnect a heater hose from the bringing pipe of the water pump.
18. Turn off a key "on 13" a nut of fastening of a tip of a "mass" wire …
19. … also remove a wire.
20. Disconnect a fuel hose from the tube fixed on a motor board.
21. Disconnect jet draft from the transmission (see. "Removal and installation of the transmission").
22. Disconnect draft of gear shifting from the transmission (see. "Removal and installation of the transmission").
23. Remove the additional muffler as its reception pipe interferes with lowering of the engine down (see. "Replacement of the additional muffler").
24. Disconnect the lower end of a cable of the drive of coupling from the transmission (see. "Replacement of a cable of the drive of switching off of coupling").
25. Have a bite the collar which is pulling together a cable of the drive of a butterfly valve and a hose of ventilation of a case of the engine and take away a cable from the engine.
26. Disconnect levers of a forward suspension bracket from rotary fists for what a key "on 17" turn out two bolts of fastening of spherical support to fists on both sides of the car.
27. Operev an assembly shovel on a transmission case, squeeze out from it internal hinges of left …
28. … and right drives of forward wheels. Take away drives from the transmission, moving outside the corresponding damping racks of a forward suspension bracket.

Note
Movement of damping racks is interfered by steering drafts. To exclude their influence, at a detachment from the transmission of the right drive turn out a steering wheel against the stop to the left, and at a detachment of the left drive — to the right.

Preventions
Disconnect the right drive only after removal of a forward cover of a case of coupling (see. "Replacement of laying of an oil case"), differently an assembly shovel it is possible to bend a cover and a flywheel will touch it.
Do not disconnect at the same time both drives as in this case in differential gear wheels of half shafts can be displaced and it will be impossible install drives without dismantling of the transmission. In need of a detachment of both drives after a detachment of one of them insert a technological cap or the old case of the internal hinge on its place and tie a cap or the case to the transmission a wire that they did not drop out at removal of a box. After that disconnect the second drive.

29. Make sure that all wires, hoses and governing bodies are disconnected from the power unit.
30. Fix slings of the load-lifting mechanism on the engine and pull them a little to unload pillows of support of the power unit.
31. Turn out a key "on 15" a bolt of fastening of a bar of the right support of the power unit to a cross-piece.
32. Turn out a key "on 15" a bolt of fastening of a bar of the left support of the power unit to a body.
33. Turn off a key "on 15" a nut of fastening of an arm of a back support of the power unit to a pillow of a support and turn out a key "on 13" two bolts of fastening of a pillow to a body. Remove a support pillow (see. "Replacement of support of the power unit").
34. Turn off a key "on 17" a nut of fastening of an arm of a forward support of the power unit to a pillow of a support and turn out a key "on 13" two bolts of fastening of a pillow to a body. Remove a support pillow (see. "Replacement of support of the power unit").
35. Establish in advance prepared support under the engine, lower on it the power unit, raise the car and take out from under it the engine.

Good advice
In this section removal of the engine down according to recommendations of manufacturer is described (as a part of the power unit, together with the transmission). Lifting mechanisms are for this purpose necessary to lift above a forward part of the car. In garage conditions it is simpler to remove the engine up, previously having removed the transmission. In this case it is not required to remove the additional muffler.

36. Install the engine as it should be, the return to removal. After installation fill in oil in a case of the engine and liquid in the cooling system.
37. Adjust drives of a butterfly valve (see. "Replacement of a cable of the drive of a butterfly valve") and controls of the transmission (see. "Adjustment of the drive of control of the transmission").
38. Launch the engine and check whether there is no leak of fuel, oil and cooling liquid. Check oil pressure. Listen to the engine: it has to work exactly, without extraneous noises and knocks.
