Removal

ATTENTION
At performance of all installation works, in particular in a motor compartment because of dense configuration, pay attention to the following: (for example fuel, hydraulic, an absorber with absorbent carbon, systems of cooling, a coolant, pipelines of brake system, vacuum hoses), and also electric wires it is necessary to lay lines of all types how they were laid initially.
Provide sufficient free space to all mobile and hot components to avoid damage of any sort of lines.

Remove the shumoizolyatsionny screen.
Remove an arm of fans together with fans of system of cooling.
Bring a radiator frame into service situation.
Mark the direction of a course of a poliklinovy belt and remove it.
Remove the right and left covers of a gear belt.
Mark with a waterproof felt-tip pen the course direction on a gear belt.
Bring the crankshaft into the top dead point. The mark in a cover of a gear belt A should coincide with a notch on a belt pulley of Century.

Fig. 2.106 . Combination of openings in adjusting plates


Check the provision of gear wheels of cam-shafts. Large openings in adjusting plates (fig. 2.106) should settle down the friend opposite to the friend on inside.

NOTE
If large openings are located on outer side of gear wheels, it is necessary turn the crankshaft on one turnover of the direction of rotation of the engine.


Fig. 2.100 . Carving cap


Unscrew a carving cap at the left from the block of cylinders (fig. 2.100) . The opening of VMT of the crankshaft should be visible behind an opening of a carving cap and to be felt to the touch.
Accurately twist fixing bolt 3242 in an opening against the stop and thus fix the crankshaft from a prokruchivaniye.
Remove an average cover of a gear belt.
Turn off a damper of krutilny fluctuations.

NOTE
The damper of krutilny fluctuations is fixed to the crankshaft by 8 bolts.


Fig. 2.107 . Bolts of fastening of a cover of a natyazhitel of a gear belt


At first turn off a bolt 1 from the case of the oil filter, then bolts of 2 covers of a natyazhitel of a gear belt (fig. 2.107) .
Uncover.

NOTE
Natyazhitel of a gear belt has an oil emphasis. Therefore it is compressed slowly.
For fixing of a natyazhitel use a lock pin of T40011.
If necessary level openings in the case and on the piston of a natyazhitel before a tension by means of nippers or a thin wire.

Fig. 2.108 . Natyazhitel and lever of a tension roller


Scroll the lever of a tension roller of a gear belt 1 internal shestigrannik in the direction (fig. 2.108) .
After the lever will be compressed by a natyazhitel 2 so that openings were in the case and the piston the friend opposite to the friend, fix a natyazhitel a lock pin of T40011.

Fig. 2.109 . Installation of a clip of cam-shafts of T4000


Insert a clip of cam-shafts of T4000 into adjusting plates of cam-shafts and turn off fixing bolts, having turned them approximately on 5 turns (fig. 2.109) .
Remove a clip of cam-shafts of T40005.

Fig. 2.110 . The adaptation for removal of a gear wheel of cam-shafts


After that by means of a two-handled stripper of T40001 and a hook of T40001/2 remove gear wheels of cam-shafts from a cone (fig. 2.110) .

Fig. 2.111 . Tension roller


Turn off a tension roller (see fig. 2.111 ) and remove a gear belt.

Installation and tension

Fig. 2.112 . Scheme of laying of a gear belt


At first lay a gear belt on a crankshaft 1 gear wheel, then on a by-pass roller of a natyazhitel 2 and after on a tension roller 3. Further, as it is represented in drawing, on gear wheels of cam-shafts and a remenny pulley of the pump of system of cooling (fig. 2.112) .

NOTE
If the belt was maintained earlier, it is necessary pay attention to a mark about the course direction.

NOTE
Gear wheels of cam-shafts should be scrolled a little more on cones of cam-shafts.

Again establish a clip of cam-shafts of T40005 on gear wheels.

Fig. 2.113 . Drill installation


Put 5 mm a drill between the tension lever and the piston of a natyazhitel (fig. 2.113) .

Fig. 2.114 . A tightening of the weakened belt


Tighten still the weakened tension roller a dinamometrichesky key of V.A.G 1410 with the got graggers of VAS 5122 and a key for tension rollers of T40009 counter-clockwise (fig. 2.114) with the moment of an inhaling of 4 N · m.
In this situation Tighten a bolt 1 on 22 N · m.
After that take 5 mm a drill.
Scroll the lever of a tension roller of a gear belt 1 internal shestigrannik in the direction (fig. 2.114) .
After the lever will compress the piston in a natyazhitel of a gear belt 2, take out a lock pin of T40011.

Fig. 2.115 . Drill installation


Turn the lever of a tension roller of a gear belt 1 internal shestigrannik in the direction (fig. 2.115) and put between the case and the lever 7мм a drill.
Fasten gear wheels of cam-shafts with the moment of an inhaling of 55 N · m.
Remove a clip of cam-shafts – T40005.
Again take out a drill inserted between the case and the tension lever.

Fig. 2.101 . A fixing bolt


Unscrew fixing bolt 3242 of an opening, twirl a carving cap (fig. 2.101) and tighten it on 30 N · m.

Fig. 2.116 . Adjusting size A


Scroll the crankshaft two times in the direction of rotation of the engine and Check the adjusting size A (fig. 2.116) . Preset value of 5 mm.
Further installation is carried out in return sequence.
