Weaken a bolt of fastening of a tension roller and the screw-driver wring out a tension roller from a gear belt (fig. 4.6). After weakening of a tension of a gear belt tighten a bolt of fastening of a tension roller again.
Mark with chalk, a marker or paint the direction of rotation of a gear belt. If at installation the gear belt rotates in other party, it will lead to its destruction. Pulleys of the engine rotate clockwise.
Take off a gear belt. After removal of a gear belt do not turn pulleys.
If it is necessary to turn the camshaft, previously install all pistons in the middle of their course. For this purpose put with chalk a tag from above on a pulley of a bent shaft, at the same time the bent shaft has to be in the provision of VMT of the first cylinder, then turn a pulley of a bent shaft on 1/4 turns (90 °) to the left or to the right. Now the tag has to be directed respectively to the left or to the right.

PREVENTIONS
Before removal of a gear belt double-check whether the tag on a pulley raspredelitelno coincides with edge of a head of the block of cylinders in bulk, and if necessary modify the provision of pulleys.
If it is necessary to turn the camshaft at the taken-off gear belt, any piston should not be in VMT, otherwise pistons and valves can be seriously damaged.
Do not bend and do not turn a gear belt. Surely replace the polluted, damaged or worn-out belts. Check uniformity and ease of rotation of a tension roller.

Installation

Fig. 4.7. Combination of a tag (1) on a pulley of a bent shaft with a tag on a forward cover of the block of cylinders


Make sure that the tag on a pulley of a bent shaft coincides with a tag on a forward cover of the block of cylinders (fig. 4.7), and the tag on a pulley of the camshaft coincides with a tag on a back casing of a gear belt. If necessary turn pulleys before combination of all tags.
Establish a gear belt on pulleys. Impose an old belt according to earlier put arrow designating the direction of rotation of a belt.

PREVENTION
Make sure that the belt well covers pulleys and does not sag.

Adjustment of a tension of a belt
Weaken a bolt of fastening of a tension roller so that the roller could move to a gear belt under effort of a spring. Turn a bent shaft on two turns clockwise before combination of a tag of the camshaft with a tag on a back casing of a gear belt. Be once again convinced that all tags coincide.
Tighten a bolt of fastening of a tension roller the moment of 45 N • m.
Turn a bent shaft on two turns in the direction of rotation of the engine and double-check combination of tags.

Fig. 4.8. Place of check of a deflection of a gear belt


The branch of a gear belt between pulleys of the water pump and camshaft has to cave in on 10,5–12,0 mm when pressing a belt by effort of 10 kgfs (strong pressing by a finger) (fig. 4.8). Otherwise weaken a bolt of fastening of a tension roller and once again adjust a belt tension.
Establish and fix by bolts the right and left casings of a gear belt, having tightened bolts the moment of 10 N • m. Establish and fix a quencher of fluctuations (shock-absorber) of the engine.
Establish a pulley of a bent shaft with a washer and fix by bolts, having tightened their moment 30 N • m.
Screw glow plugs.
Establish and pull maple a belt.
Establish a casing in the right wheel niche.
Connect a wire to the negative plug of the rechargeable battery.
If there are hours, determine time and enter a security code into the radio receiver.

Back gear belt
Removal
Disconnect a wire from the negative plug of the rechargeable battery.

PREVENTION
At a wire detachment from the negative plug of the rechargeable battery memory of electronic memory devices, for example a radio receiver code is erased.

Turn out glow plugs.

Fig. 4.9. Back gear belt: 1 – cover of a head of the block of cylinders; 2 – nut of fastening of a tension roller; 3 – casing of a gear belt


Turn out bolts and remove a casing of a back gear belt (fig. 4.9).
Weaken a nut of fastening of a tension roller of a gear belt.

The screw-driver take away a tension roller from a gear belt and tighten a nut (fig. 4.10).
Mark with chalk, a marker or paint the direction of rotation of a gear belt. If at installation the gear belt rotates in other party, it will collapse. Pulleys of the engine rotate clockwise.

PREVENTION
Do not bend and do not turn a gear belt. Surely replace the polluted, damaged or worn-out belts. Check uniformity and ease of rotation of a tension roller.

Installation
For a provorachivaniye of a bent shaft of the engine lift a forward wheel of the car, include the 5th transfer and turn a wheel a hand.

PREVENTION
Do not turn a bent shaft of the engine for a camshaft pulley in order to avoid an overload of a forward gear belt at all.

Establish a gear belt on pulleys. Impose an old belt according to earlier put arrow designating the direction of rotation of a belt.

PREVENTION
Make sure that the belt well covers pulleys and does not sag.

Turn a bent shaft on two turns in the direction of rotation of the engine and double-check combination of tags.
The branch of a gear belt between pulleys of the fuel pump of high pressure and the camshaft has to cave in on 9,5–12,0 mm when pressing a belt by effort of 10 kgfs (strong pressing by a finger). Otherwise weaken a bolt of fastening of a tension roller and once again adjust a belt tension.
Establish and fix by bolts a casing of a gear belt, having tightened bolts the moment of 10 N • m.
Screw glow plugs.
Connect a wire to the negative plug of the rechargeable battery.
