3.3.5.2. Dismantle and installation
THE GENERAL DATA

The prevention

Before performance of works familiarise with the maintenance of the present subsection. The manufacturer engine dismantle in gathering with transmission by a raising of all power unit upwards and removals from a motor compartment is recommended. Transmission separates from the engine after removal of the power unit and lowering on a workshop floor. If transmission repair is not planned, it is possible to remove the engine separately, and transmission to leave on the car. The engine acts in film by lifting upwards and removals from a motor compartment for what it is necessary to remove a pulley коленвала and to raise the engine from outside a gear belt, not to touch a body.


Dismantle
The prevention

Considered cars are equipped by safety pillows. At any moment at the connected battery the pillow (which has a rigid design) can be developed to (be inflated). To exclude casual operation of a pillow (and possible traumas) at performance of any works near to details of a pillow of safety turn the ignition key in position LOCK and disconnect the battery from weight. After switching-off of the battery wait two minutes (necessary for a full discharge of the reserve condenser). More detailed description is resulted in subsection 11.44.


PERFORMANCE ORDER
1. Execute actions on декомпрессии fuel system (subsection 5.2 see).
2. Disconnect the battery from weight.
3. Remove the battery and a battery tray.
4. Remove the battery and a battery tray.
5. Remove protective panels of wings, a cowl and an air inlet lattice.
6. Remove the air filter.
7. Lift the car and establish on supports. Merge a liquid from cooling system, oil from the engine and remove drive belts.
8. Designate and disconnect all sockets of conducting and hoses.
9. Remove a tank of a washer of a windscreen and a tank of a cooling liquid.
10. Remove the fan, a casing and a radiator.
11. Disconnect heater hoses.
12. Dump residual pressure of fuel in a tank for what turn away a stopper of a jellied mouth and disconnect and muffle fuel tubes.
13. Disconnect on the engine cables throttle заслонки, the throttle valve of transmission and the cruise-control (if it is provided).
14. Remove a forward lattice and a radiator partition.
15. Disconnect wires of transmission and take away in the parties.
16. On the cars equipped with the hydraulic booster, turn away bolts of the pump of the hydraulic booster. Take the pump aside, without disconnecting hoses. If necessary remove the pump.
17. On the cars equipped with the conditioner, turn away bolts of fastening and take the compressor aside. Hoses not to disconnect.
18. Would disconnect from a collector (ditch) an exhaust pipe.
19. Disconnect hoses and remove маслоохладитель (if it is provided).
20. Attach to the engine тали the lift and choose a weak point to a small tension тали.
21. Disconnect semiaxes and карданный a shaft (subsection 7.8 and subsection 7.3.2 see).
22. Turn away bolts of fastening of support of the engine.
23. On the cars equipped with automatic transmission, remove a protective casing in the bottom part картера transmissions. Turn away bolts of fastening of the hydrotransformer to a leading disk and slightly submit the hydrotransformer towards transmission.
24. Turn away bolts of fastening of transmission to the engine and separate the engine from transmission. The hydrotransformer should remain on transmission.
25. Be convinced that all details connecting the engine with a body or transmission are removed. All remained details designate and remove.
26. Fix картер transmissions, having established a support and having laid a board. Turn out bolts of support of the engine, except what concern transmission.
27. Cautiously raise the engine (or the power unit in gathering) from a motor compartment. If necessary separate support from frame arms.
28. Take the engine aside from the car and cautiously lower.

Installation

PERFORMANCE ORDER
1. Check up a condition of support of the engine. At detection of damages or support wear tracks replace.
2. On cars from a manual transmission check up a coupling condition (subsection 7.2 see), and on cars with automatic transmission, examine an epiploon of the hydrotransformer and the plug.
3. On cars from a manual transmission grease directing bearing with refractory greasing.
4. Cautiously establish transmission on the engine. It is forbidden to force installation картера a check point an inhaling of bolts.
5. Tighten bolts of fastening of transmission with the set moment.
6. Attach to the engine таль and cautiously lower the engine (or the power unit) in a motor compartment.

The prevention

If the engine acted in film without transmission lower the engine until then while the assistant will not combine adjusting pins on the block of cylinders with transmission. For correct combination of transmission with the engine the manipulation both units is required.
