Repair Sharan/Sharan Volkswagen>> Diesel engine>> Driving belts — poliklinovy and gear>> Removal of a gear belt
The gear belt can be removed on the established engine, and we will start with it at the following description.
Remove the plug of a "mass" wire from AB.

Fig. 390. To remove the air filter, disconnect: 1 — a hose going to a vacuum regulator of system of a retsirkulyatsiya of OG; 2 — the sensor of a mass consumption of air; 3 — an air inlet; 4 — an inlet hose

Remove the air filter as it was described (see fig. 390 ).

Fig. 391. Removal of a cover of the engine: 1 — a hose of forced air; 2 — a cap

Uncover the engine and a hose of forced air. Remove a cap 2 (see fig. 391 ) and a spring clip. Press a cover in the arrow direction aside and disconnect a hose of forced air 1 from an inlet collector.

Fig. 392. Removal of a cover of a head of the block of cylinders: 1 — a hose; 2 — safety caps; 3 — a spring collar

Uncover heads of the block of cylinders (the case of ventilation of a case remains on a head of the block of cylinders). Disconnect a hose 1 (see fig. 392 ) from a cover of the block of cylinders, weaken a spring collar 3 inlet hoses and disconnect a hose. Remove safety caps 2 (two are shown by shooters) and unscrew three nuts located under them. Uncover heads of the block of cylinders.
For dismantle of the engine it is necessary to raise the engine, to remove a forward hydraulic support of the engine, a collar of an engine mount and to remove a gear belt. For this purpose fix the engine stropovochny loops and raise it by means of the lift so that to unload an engine mount. Unscrew an engine mount from a hydraulic support (2 bolts) and from an engine mount collar (3 bolts). Be surely convinced that the engine is reliably fixed in trailing situation.
Lift a forward part of the car and remove protection of a case. Disconnect an arm of the pipeline of the pump of the hydraulic booster of a steering (1 bolt).
Unscrew an engine mount collar from a forward part of the engine. After untwisting of bolts at once lower the car on wheels.
Remove poliklinovy a belt and the top safety cover of a gear driving belt.
Disconnect two clamps and remove the top protection of a gear driving belt.

Fig. 415. In the top drawing the adjusting calibre established on a camshaft 1 is shown. In the bottom drawing it is shown, how the flywheel from well-aimed VMT should be located

The special tool is necessary for further work (for VW — 2065A, to Ford — 21-105). The tool represents adjusting calibre for a camshaft which is established from a flywheel after the engine will be in situation VMT. Turn the engine so that marking on a flywheel stood on one line with an adjusting pin (turn out a cap from the top part of a transmission) as it is shown on fig. 415 . To make exact adjustment, it is necessary to perform the following works:
- turn a camshaft so that the end of adjusting calibre settled down opposite to a head of the block of cylinders;
- measure a crack on other party with the help щупа;
- prepare щуп which thickness is equal to a half from the found size and move it between calibre and a head of the block of cylinders;
- now turn a camshaft so that the calibre was imposed on щупы;

Fig. 416. Both щупа are inserted between adjusting calibre and a surface of a head of the block of cylinders

- move the second щуп the same thickness on the other hand between calibre and a head of the block of cylinders. Operation is shown on fig. 416 .
Put a forward part of the car on support to have possibility to reach the lower part of the car.
Disconnect a quencher of krutilny fluctuations of a cranked shaft (4 bolts) and a pulley of the water pump (3 bolts). At performance of this operation the specified shaft should be fixed in motionless situation.
Unscrew three bolts and remove the bottom protection of a gear belt.
Lower the car again on soil.

Fig. 417. Fixing of a cogwheel of TNVD in motionless situation by a clamp 1

For carrying out the following operation you again will need the special tool — 2064 (VW) or 23-047 (Fords) which it is necessary to establish as it is shown on fig. 417 on a cogwheel of TNVD to fix it in motionless situation. The tool represents a persistent pin in diameter of 15,45 mm which it is possible to replace with a round piece of any material. The persistent pin should be inserted through an opening in TNVD pulley into the corresponding opening on a pump arm.
Remove the directing roller of a gear driving belt located in the top part of a gear belt of a drive of GRM.

Fig. 418. After the tension roller shown by an arrow will be weakened, it will be possible to remove a belt

If you plan to establish a belt again, on a belt it is necessary to make a mark which should show the direction of its movement. After the nut will be turned off, weaken the device for a belt tension, having turned it to the left. The device will release a belt ( fig. 418 , it is shown by an arrow) and its tension will weaken.
Release a pulley and remove a driving belt from cogwheels.
