Repair Sharan/Sharan Volkswagen>> Diesel engine>> Driving belts — poliklinovy and gear>> Installation of a gear driving belt and drive adjustment gazorasprede-litelny mechanism

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





At installation of a new driving belt or at repeated installation of an old belt first of all be convinced that the flywheel costs in the situation shown on fig. 415 .
Unscrew on 1/2 turns a bolt of a cogwheel of a camshaft (without turning thus a shaft) and strike on it with a plastic or rubber hammer to weaken conic landing of a cogwheel on a shaft. When using an old driving belt establish it according to a mark concerning the movement direction.
Tighten directing roller of a gear belt (25 N · м) also take out a persistent pin from TNVD cogwheel.

Fig. 419. Installation of a gear belt. Pay attention to coincidence of labels on a tension roller (insert with an arrow in drawing). Instead of the special tool it is possible to apply slanted nippers to removal of spring lock rings: 1 — a running roller; 2 — the special tool or nippers for removal of spring lock rings; 3 — a tension roller; 4 — a lock pin





Examine a tension roller. It has edge and a groove which should coincide with each other. On fig. 419 it is shown, how the belt at this stage of installation looks.
Now press a tension roller nippers of a spring lock ring against a spring tension (the direction 3 on fig. 419 ) and tighten a nut of a tension roller the moment of 20 N · m.
Fix a camshaft cogwheel in motionless situation and tighten a bolt the moment of 45 N · m.
Remove adjusting calibre on the other side of the engine.
Again establish all details. Raise or again lower the car on soil to have possibility to reach separate details.
Rotations of a pulley of a cranked shaft turn the engine on two complete revolutions. After that check, whether there corresponds still situation VMT.
After adjustment of a driving belt check injection adjustment.
Establish the bottom protection of a gear driving belt (3 bolts).
Fasten a pulley of a cranked shaft with a quencher of krutilny fluctuations on a cogwheel of a drive of the gas-distributing mechanism and tighten four bolts the moment of 25 N · m. Thus the adjusting pin on a cogwheel of a cranked shaft should enter into an opening on a quencher of fluctuations. At an inhaling of connection fix a cranked shaft in motionless situation (it is possible to include transfer).
Establish the top protection of a gear belt. It should enter into a fillet of the bottom protection.
Establish a remenny drive, and also maple a belt of the pump of the hydraulic booster of a steering and adjust their tension.

Fig. 393. Unscrew bolts 1 and 2





Again establish a collar of a suspension bracket of a forward support of the engine (big bolts are tightened by the moment of 58 N · m, small bolts the moment of 23 N · м) and an engine support. On fig. 393 engine mount fastening from the face is shown.
