3.1.2.4.1. Dismantle and installation of the power unit

GENERAL INFORMATION

Prevention

Before works familiarize with contents of the present section. The manufacturer recommends engine dismantle assembled with transmission by a raising of all power unit up and removals from a motor compartment. Transmission separates from the engine after removal of the power unit and lowering on a workshop floor. If repair of transmission 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 up and removals from a motor compartment for what it is necessary to remove a pulley of the crankshaft and to raise the engine from a gear belt, not to touch a body

. Considered cars are equipped with safety cushions. At any time 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 details of a safety cushion turn the ignition key in the situation LOCK and disconnect the battery from weight. After shutdown of the battery wait two minutes (necessary for a full discharge of the reserve condenser). More detailed description is provided in subsection 12.24


Dismantle

PERFORMANCE ORDER
1. Execute actions for a decompression of fuel system (see subsection 5.2).
2. Disconnect the battery from weight.
3. Remove the battery and a battery tray.
4. Remove a cowl, having spread a sheeting (see subsection 11.8).
5. Remove the air filter (see subsection 5.9).
6. Lift the car and establish on supports. Merge liquid from cooling system, oil from the engine and remove drive belts (see subsection 2.6.4).
7. Put accurate labels on hoses of system of cooling and decrease in toxicity of exhaust gases, on vacuum hoses, sockets of conducting, the tire of connection with weight and gasoline pipe lines. The put labels paste a sticky tape or put with paint that they were well visible. Make instant pictures or sketch a relative positioning of details and arms.
8. Remove a tank of a washer of a windscreen and a tank of cooling liquid.
9. Remove the fan (ы) and a radiator (see subsection 4.8 and subsection 4.5).
10. Disconnect heater hoses.
11. Dump residual pressure of fuel in a tank for what unscrew a stopper of a jellied mouth and disconnect fuel tubes from the engine (see subsection 5.2).
12. Disconnect on the engine draft of a butterfly valve, draft of the throttle valve of transmission and a gear shifting cable (if is available).
13. Remove the battery and a battery tray (see subsection 3.3.2).
14. Remove soaking-up and final collectors, being guided by the description in subsection 3.1.1.4 and subsection 3.1.1.5.
15. On the cars equipped with the hydraulic booster, unscrew bolts of the pump of the hydraulic booster. If the place suffices, adhere the pump, having taken aside, without disconnecting hoses. If necessary disconnect hoses (see subsection 10.19).

Prevention

Tie up the compressor a wire, do not allow, that it hung on hoses.


16. Attach to the engine slings, bring таль the lift and fix slings on a waist. Choose a weak point to a small tension of a waist.
17. Remove semi-axes (see subsection 8.3).
18. Unscrew a coupling bolt of a back support of the engine (from a wall of a motor compartment), get rubber caps from a longitudinal longeron of a support of the engine and unscrew four nuts and five bolts (see subsection 7.1.5).
19. Remove drive belts, a pulley of the pump of cooling liquid and a crankshaft pulley.
20. Unscrew a bolt of fastening of a support of the engine from a radiator to the chassis.
21. On the cars equipped with automatic transmission, get from the lower part of a case of transmission the plastic filter. Unscrew bolts of fastening of the hydrotransformer to a leading disk (see subsection 7.2.8) and slightly submit the hydrotransformer towards transmission.
22. Unscrew bolts of fastening of transmission to the engine and separate the engine from transmission (see subsection 7.1.5). The hydrotransformer should remain on transmission.

Prevention

If with the engine transmission acts in film also, it is necessary to disconnect the left support of the engine, cables, conducting and hoses from transmission. Bolts of fastening of transmission to the engine at this stage not to turn on.


23. Be once again convinced that all details connecting the engine to a body or transmission are removed. All remained details remove previously having marked.
24. Fix a transmission case, having established a support and having laid a board not to damage a case. Unscrew bolts of support of the engine, except what belong to transmission.

Prevention

After posting of the power unit performance of any works under the engine or transmission is forbidden.


25. Carefully lift the engine (or the power unit assembled) from a motor compartment. If necessary wring out support from arms of a frame of the engine.

Prevention

At engine dismantle from the car equipped with a manual transmission in that case when the check point remains on the car, it is required to lower a check point by means of a support. It is necessary to incline the engine and to get it from a motor compartment.


26. Take the engine aside from the engine and carefully lower against the stop in a floor, or remove a leading disk (coupling) and establish the engine on the stand or a workbench.

Prevention

On the cars equipped with automatic transmission, put labels on internal and external remote washers (if are available) and store washers together with a leading disk.



Installation

PERFORMANCE ORDER
1. Check a condition of support of the engine. At detection of damages or wear tracks of a support replace.
2. On the cars equipped with a manual transmission, check a coupling condition (see subsection 8.2), and on the cars equipped with automatic transmission, examine an epiploon of the hydrotransformer and the plug.
3. On the cars equipped with automatic transmission, put on a nasal part of the hydrotransformer of a little konsistentny greasing.
4. Carefully establish transmission on the engine, being guided by the description in subsection 7.1.5 and subsection 7.2.8.

Prevention

If transmission badly gives in to installation, at all it is not necessary to force installation by an inhaling of bolts. Otherwise breakages of a case or the block of cylinders are possible.


5. Wrap bolts of fastening of transmission to the engine and tighten with the moment specified in subsection 7.1.1.
6. Attach to the engine таль and carefully lower the engine (or the power unit) in a motor compartment.

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. The correct combination of transmission with the engine needs a manipulation by both units.


7. Reliably tighten fastening bolts.
8. Establish other removed details and fastening elements upside-down.
9. Restore liquid level in system of cooling, oil in the engine, liquid in automatic transmission and a steering hydraulic actuator (see subsection 2.8.4, subsection 2.5.1.1 and subsection 2.5.1.2).
10. Start the engine, check operation of the engine and existence of leaks. Stop the engine and check level of liquids in all systems.
