Removal and installation of a gear belt



Operations and the corresponding instructions concerning all engines, are resulted in subsection Removal, installation and a tension of a gear belt. In the present subsection the differences concerning engine TDI of 1.9 l are described only.

1. Turn away a tension roller клинового a belt at the holder.
2. Remove the vacuum pump of the amplifier of a brake.
3. Establish коленвал the engine in position ВМТ of the piston of the first cylinder (subsection Installation of the piston of the first cylinder in ВМТ). In this position it is possible to insert an adjusting ruler into a camshaft crack 3418. The ruler interferes with possibility проворачивания a camshaft. If it is necessary, the ruler can be made most.
4. Installation of an adjusting ruler in parallel a head of cylinders: For this purpose turn a cranked shaft so that the ruler end adjoined a head of cylinders. On other end of a ruler probeом measure the formed backlash. Insert probe in the thickness equal to half turned out between ruler and a head of cylinders. Now turn the engine so that the ruler has laid down on probe. Insert the second probe the same size on other end between a ruler and a head of cylinders.
5. In an aperture the coupling casing opposite each other has label ВМТ of a flywheel and a base label.
6. Fix pulley ТНВД core AUDI–3359. Instead of the specified core another can be applied approaching, for example, a drill. Turn out one after another fastening bolts (arrows on an accompanying illustration) and replace with new bolts. Tighten bolts the moment 20 Н m.


The central bolt on ТНВД do not turn on, since it can break pump adjustment. Independent carrying out of adjustment ТНВД is inconvenient.

7. Застропьте the engine also turn away the right support of the engine and демпфер fluctuations, address to subsection Removal, installation and a tension of a gear belt.
8. Remove a gear belt.
9. Turn on on Ѕ a turn a bolt of fastening of a cogwheel of a camshaft at the removed gear belt.


At отворачивании wheels keep a camshaft a wrench for лыски. It is not necessary to use an adjusting ruler as means for deduction.

10. Turn away cogwheel fastening. Remove a cogwheel of a camshaft from a cone hammer blows on выколотке through an aperture in a back protective cover of a gear belt.
11. Put on a gear belt. At installation of the belt which was in work keep behind a direction of its rotation. Put at removal of a belt of the marksman specifies in a direction of rotation of the engine, i.e. In an hour hand direction. Put on a belt in sequence: the pulley of a cranked shaft rejecting a roller, the pump of a cooling liquid, pulley ТНВД and a tension roller.
12. A camshaft pulley put together with a belt on a camshaft and fix by hand a bolt. The camshaft pulley should rotate on a shaft.
13. Take out a clamp of pulley ТНВД.
14. Turn a tension roller the tool, for example, HAZET 2587 to the right so that have coincided a label on a tension roller and a ledge.
15. Tighten a tightening nut on a tension roller the moment 20 Н m.
16. Once again check up, whether coincide marks ВМТ on a flywheel and base marks.
17. Fix a pulley of a camshaft the moment 45 Н m, keeping thus a shaft from проворачивания a key.
18. Clean on distributive to a shaft an adjusting ruler.
19. Take out core AUDI–3359 at pulley ТНВД.
20. Turn a cranked shaft on two turns and again stop in position ВМТ of the first cylinder.
21. Check up, whether pulley ТНВД is fixed by core AUDI–3359. If the core is not inserted, turn away bolts of fastening of pulley ТНВД and turn a nave so that the core has entered.
22. Fix the holder of the engine at the block of cylinders the moment 45 Н m.
23. Tighten engine support.


Bolts in the course of an inhaling receive residual deformation. Therefore after each inhaling they should be replaced. Fix the holder of the engine at a support the moment 60 Н m and then tighten a rigid key on a corner 90 (1/4 turns). Fix engine support to a body the moment 40 Н m and then tighten a rigid key on a corner 90 (1/4 turns).

24. Establish on the places a protective casing of a gear belt, демпфер fluctuations. A tension roller клинового a belt and a cover of a head of cylinders.
25. Establish клиновой a belt, address to subsection Removal and installation клинового a belt.
26. Check up the beginning of injection ТНВД (work HUNDRED).


After adjustment of the beginning of injection of fuel it is necessary to tighten the moment 20 Н m bolts of fastening of pulley ТНВД and then to tighten their rigid key on a corner 90 (1/4 turns). After an inhaling of bolts it is necessary to replace with their specified way on new after everyone отворачивания.
