2.3.4. Removal and installation of a gear belt

Removal

Fig. 2.54. Engine casing


Remove a casing of the engine (fig. 2.54).

ATTENTION
When opening the broad tank can come out hot steam or hot cooling liquid. Wrap up a cover rags and carefully open a tank.

Open a cover of a broad tank of the cooling system.

Fig. 2.44. Bolts of an exhaust pipe of an independent additional heater


In cars with an additional heater unscrew bolts of an exhaust pipe of an independent additional heater from the noise-insulating screen (fig. 2.44).

Fig. 2.45. Fastening of a forward noise isolation


Weaken quick disconnect couplings 1 and 2 and remove a forward noise isolation (fig. 2.45).
Merge cooling liquid.
Bring a radiator frame into service situation.

Fig. 2.102. Tube of cooling liquid


Disconnect a tube of cooling liquid (fig. 2.102).

NOTE
Before removal of a poliklinovy belt mark the direction of the course with chalk or a felt-tip pen. Change of the direction of the course of earlier operated belt can lead to its damage.

Mark the direction of the course of a poliklinovy belt.

Fig. 2.64. Weakening of a poliklinovy belt


For weakening of a poliklinovy belt turn a tension damper on an arrow (fig. 2.64).
Record a tension element with the help by a clamp.
Take off a poliklinovy belt.

Fig. 2.103. Installation of a gear wheel of a cam-shaft on mark VMT


Put a cam-shaft gear wheel, having scrolled the crankshaft, on mark VMT. The mark in a gear wheel of a cam-shaft has to coincide with an arrow on the protection cover of a gear belt (fig. 2.103).

Fig. 2.98. Untwisting of a belt pulley of the crankshaft


Remove a damper of fluctuations / a belt pulley (fig. 2.98).

Fig. 2.104. Bolts of fastening of the lower part of the protection cover of a gear belt


Turn off bolts of the lower part of the protection cover of a gear belt (fig. 2.104).

Fig. 2.105. Bolts of fastening of the top part of the protection cover of a gear belt


Unscrew the remained screws of fastening of the protection cover of a gear belt and remove the protection cover of a gear belt from the engine (fig. 2.105).
Mark the direction of the movement of a gear belt.
Turn off a tension roller and take off a gear belt.
Then slightly turn the crankshaft back.

Installation
The engine has to be warm to the touch.

NOTE
When scrolling a cam-shaft any of pistons should not be in VMT. At the same time there is a danger of damage of the valves / bottom of the piston.

Impose a gear belt on a crankshaft gear wheel (observe the direction of the course).
Fix the lower part of the protection cover of a gear belt by two lower screws.
Establish a damper of fluctuations / a belt pulley, having fastened them new screws.
Turn the crankshaft and a cam-shaft in the provision of VMT of the first cylinder (fig. 2.103).

Fig. 2.106. Laying of a gear belt


Lay a gear belt in the sequence: a tension roller, a cam-shaft pulley, a pulley of the water pump and, in the last turn, an intermediate roller (fig. 2.106).

NOTE
Be convinced of correctness of installation of a tension roller in GBTs.


Fig. 2.107. Tension of a gear belt


Pull a gear belt. For this purpose scroll a face six-sided key the clown to the right (on an arrow) until the cut is established over a toe (fig. 2.107).
Again weaken a gear belt.
Now pull a gear belt, so far the cut and a toe will not be the friend opposite to the friend.
Tighten a fixing nut of a tension roller.
Make 2 turns of a bent shaft in the direction of rotation of a shaft of the engine and again install the first cylinder in the provision of the top dead point. At the same time it is important that the last 45 ° (1/8 turns) were scrolled without stopping.
Repeatedly check a tension of a gear belt. Nominal situation: the toe and a cut are the friend opposite to the friend.
Double-check gas distribution phases.
If marks do not coincide, repeat adjustment of phases of gas distribution.
If marks coincide, install the protection cover of a gear belt (fig. 2.105).
Establish a belt pulley of the crankshaft.
Establish a poliklinovy belt.
Fill in cooling liquid.
Establish a radiator frame with hinged components.

Fig. 2.96. Fastening of the rubber buffer


Lower a support emphasis against a provorachivaniye at the expense of a body weight on the rubber buffer and tighten nuts (fig. 2.96).
Establish a casing of a front bumper.
Check adjustment of headlights.
Install the sound-absorbing pallet.
Establish a cover of a motor compartment.

Inhaling moments
* Replace a bolt.
** 90 ° there correspond quarters of a turn.
*** Establish on a carving varnish.
