3.6.1. Removal and installation of a gear belt


ATTENTION

Operations and the corresponding instructions relating to all engines are given in the subsection Removal, installation and a tension of a gear belt. In the real subsection only the differences relating 1.9 l to the TDI engine are described.


PERFORMANCE ORDER
1. Turn off a tension roller of a maple belt at the holder.
2. Remove the vacuum pump of the amplifier of a brake.
3. Install the engine crankshaft in the provision of VMT of the piston of the first cylinder (the subsection Installation of the Piston of the first cylinder in VMT). In this situation it is possible to insert an adjusting range 3418 into a crack of the camshaft. The ruler interferes with a possibility of a provorachivaniye of the camshaft. If it is necessary, the ruler can be made most.
4. Installation of an adjusting ruler parallel to a head of cylinders: For this purpose turn a bent shaft so that the end of a ruler adjoined a head of cylinders. On other end of a ruler the probe measure the formed gap. Insert the probe thickness equal to the half which turned out between a ruler and a head of cylinders. Now turn the engine so that the ruler laid down on the probe. Insert the second probe of the same size on other end between a ruler and a head of cylinders.
5. In an opening the coupling casing opposite to each other has a tag of VMT of a flywheel and a basic tag.
6. Record TNVD pulley AUDI-3359 core. Instead of the specified core it can be applied another suitable, for example, a drill. Turn out one by one fastening bolts (arrows on an accompanying illustration) and replace with new bolts. Tighten bolts the moment of 20 N of m.

ATTENTION

Do not turn off the central bolt on TNVD since it can break adjustment of the pump. Independent carrying out adjustment of TNVD is difficult.


7. Zastropte the engine also turn off the right support of the engine and a damper of fluctuations, address the subsection Removal, installation and a tension of a gear belt.
8. Take off a gear belt.
9. Turn off on Ѕ a turn a bolt of fastening of a cogwheel of the camshaft at the taken-off gear belt.

ATTENTION

At an otvorachivaniye of a wheel hold the camshaft a wrench for lysk. It is not necessary to use an adjusting ruler as means for deduction.


10. Turn off fastening of a cogwheel. Remove a camshaft cogwheel from a cone blows of the hammer to a drift through an opening 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 the direction of its rotation. The arrow put at removal of a belt specifies in the direction of rotation of the engine, i.e. in the direction of an hour hand. Put on a belt in the sequence: the pulley of a bent shaft rejecting a roller, the pump of cooling liquid, a pulley of TNVD and a tension roller.
12. Put a pulley of the camshaft together with a belt on the camshaft and fix by hand by a bolt. The pulley of the camshaft has to rotate on a shaft.
13. Take out TNVD pulley clamp.
14. Turn a tension roller the tool, for example, of HAZET 2587 to the right so that coincided a tag on a tension roller and a ledge.
15. Tighten a tightening nut on a tension roller the moment of 20 N of m.
16. Double-check whether coincide marking of VMT on a flywheel and basic marking.
17. Fix a camshaft pulley by the moment of 45 N of m, holding at the same time a shaft from a provorachivaniye a key.
18. Remove on distributive to a shaft an adjusting ruler.
19. Take out AUDI-3359 core at TNVD pulley.
20. Turn a bent shaft on two turns and again stop in the provision of VMT of the first cylinder.
21. Check whether TNVD pulley is fixed by AUDI-3359 core. If the core is not inserted, turn off bolts of fastening of a pulley of TNVD and turn a nave so that the core entered.
22. Fix the holder of the engine at the block of cylinders by the moment 45 N of m.
23. Tighten engine support.

ATTENTION

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


24. Install the protection cover of a gear belt, a damper of fluctuations on the places. tension roller of a maple belt and cover of a head of cylinders.
25. Establish maple a belt, address the subsection Removal and installation of a maple belt.
26. Check the beginning of injection of TNVD (work HUNDRED).

ATTENTION

After adjustment of the beginning of injection of fuel it is necessary to tighten the moment 20 N of m bolts of fastening of a pulley of TNVD and then to tighten them a rigid key on a corner 90 ° (1/4 turns). After an inhaling of bolts in the specified way they need to be replaced on new after each otvorachivaniye.
