Engines are equipped with automatically working tension roller in a drive of the gear belt, supporting a belt tension always to constants. Thanks to it service life raises and the noise level of a gear belt decreases.
REMOVAL
|
PERFORMANCE ORDER
|
| 1. Remove maple a belt, thus address to the subsection Removal and installation of a ridge maple belt. |
| 2. Unscrew a tension element of a maple belt. |
| 3. Establish the crankshaft in the provision VMT of the end of a step of compression of the piston of the first cylinder, thus address to subsection Installation of the piston of the first cylinder in VMT. |
|
4. As the right support of the engine is disconnected, the engine is necessary for suspending on the AUDI-10-222A adaptation and 10-222A/1. It is necessary to establish the adaptation on fastening of a wing and will fix hooks for engine eyes. |
ATTENTION
If the specified adaptation available is not present, it is necessary to bring the garage lift with wooden laying under the pallet of a case and slightly to raise the engine.
|
|
5. Unscrew 4 screws with an internal shestigrannik and remove a pulley (a damper of krutilny fluctuations) from a cranked shaft. The engine thus keeps from a provorachivaniye for the central bolt. |
| 6. Unscrew bolts and remove the bottom and top covers of a gear belt. |
|
7. Unscrew bolts and remove a broad tank of cooling liquid and the tank of the hydraulic booster (are specified by shooters) and take aside with distributive lines. |
|
8. Unscrew bolts and disconnect the right support of the engine from a body and at the holder of the engine (are specified by shooters). |
|
9. Unscrew bolts and remove the right holder of the engine from the engine (are specified by shooters). |
ATTENTION
For a detachment of a forward bolt it is necessary to raise a little the engine by means of the adaptation.
|
| 10. Engines of 1.6 l: Unscrew nuts of fastening of a tension roller of a gear belt. |
| Engine of 1.8 l |
| 11. Screw a hairpin–1–М5х55 in the device of a tension of a gear belt. |
|
12. Screw a nut–2–with a big washer–3–on a hairpin–1–.
The rod of the device of a tension should be pulled until rod and case openings that will allow to insert a core in diameter of 1.5 mm, a drill or шплинт (an arrow on an accompanying illustration) will coincide. Now the rod is fixed, and the gear belt is unloaded. |
| All engines |
| 13. Remove a gear belt. |
ATTENTION
After removal of a gear belt do not change the provision of distributive and cranked shaft. If it is necessary to turn a camshaft at the removed gear belt, watch that the cranked shaft was not in VMT. Otherwise there is a danger of damage of valves and the piston bottom. For this purpose mark the provision of a pulley of a cranked shaft, having put with marking paint on a pulley of a cranked shaft and the block of cylinders. Then turn forward or back a pulley of a cranked shaft on 1/4 turns (90 °).

INSTALLATION
| PERFORMANCE ORDER |
| 1. At a tension of a gear belt the engine should be cold. |
| 2. Put on a gear belt cogwheels of a cranked shaft and the pump of cooling liquid. |
ATTENTION
If the old belt is established, surely observe the direction of its rotation. Belt installation in other situation can lead to its break and, as a result, to engine damage. Therefore gear belts surely establish so that the arrow put at removal of a belt, specified in the direction of rotation of the engine. The engine, looking on the right side of the car, rotates in the direction of an hour hand.
|
| 3. Be convinced that markings on wheels of cranked and distributive shaft coincide with the provision of marking of VMT. The engine is thus in position VMT of the piston of the first cylinder. |
| 4. Establish into place the bottom cover of a gear belt and fix it. |
| 5. Fix a pulley of a cranked shaft the moment of 25 N of m. Remark: The pulley is established only in one situation. Check, that it was fixed. |
| 6. Put on a gear belt a tension roller and a camshaft wheel. |
| Engine of 1.6 l |
|
7. Check the provision of a tension roller: the clamp (an arrow on an accompanying illustration) should enter into a groove on a head of cylinders. Otherwise turn the holder. |
|
8. Turn a tension roller for the clown a screw-driver, for example, HAZET 2587 to the left (the arrow direction) so that a notch–1–and the index–2–stood opposite. For control it is possible to use a mirror if necessary. In this situation tighten a nut the moment of 20 N of m. |
| 9. Turn the engine on 2 turns in the direction of rotation and again stop in the provision VMT of marking of a camshaft. It is thus important, that the last 45 ° were turned without stopping. |
| 10. Check the provision of a notch–1–and the index–2–, they should be opposite to each other. Otherwise it is necessary to establish a tension roller again. |
| Engine of 1.8 l |
|
11. Take out a lock core (the shooter on an accompanying illustration) and turn out a carving pin–1–. The rod at a press element watches the correct tension of a gear belt. |
| All engines |
| 12. Turn the engine twice and check the provision VMT of distributive and cranked shaft. All markings at the tense gear belt should coincide. Otherwise again remove a gear belt and repeat adjustment. |
| 13. Establish the top cover of a gear belt. |
| 14. Fix the right holder of the engine the moment of 45 N of m. |
| 15. Fix the right support of the engine on a body and the holder of the engine new bolts the moments presented in Specifications. Thus all bolts at first tighten a dinamometrichesky key, and then tighten a rigid key on a corner 90 ° (1/4 turns). |
ATTENTION
Bolts at an inhaling receive a residual extract. Therefore after each inhaling it is necessary to apply new bolts.
|
| 16. Bolts at an inhaling receive a residual extract. Therefore after each inhaling it is necessary to apply new bolts. |
| 17. Fix a tension element of a maple belt the moment of 20 N of m. |
| 18. Establish maple a belt, thus address to the subsection Removal and installation of a ridge maple belt. |
| 19. Fix a broad tank of system of cooling and the tank of liquid of the power steering. |
