Adjusting the tension of the drive belt of engine units (VW Sharan 1)

The tension of the poly V-belt is carried out by a mechanism with a built-in spring and does not require regular monitoring. Therefore, there is no need to carry out special adjustment of the belt tension if it was removed for any reason.

Although different units may be installed and different pulleys may be used to drive them, in any case only one tension roller is used.







The diagrams of the poly V-belt installation on a vehicle without air conditioning and with air conditioning are shown in (Fig. 156) and (Fig. 157), respectively.

Removal the poly V-belt is installed as follows:

• mark the direction of movement of the poly V-belt. To do this, draw an arrow in the direction of movement with a marker. The engine crankshaft rotates clockwise when viewed from the belt side;
• lever 3299 (fig. 156 and 157) loosen the tension of the poly V-belt;
• remove the poly V-belt from the power steering pump drive mechanism;
• remove the poly V-belt;
• check the condition of the poly V-belt. It should not have any cracks or breaks, peeling coating or fibers, frayed fibers, frayed or glassy side surfaces, oil or grease stains;
• a damaged poly V-belt must be replaced.

Installation the poly V-belt is installed as follows:

• turn the tension roller with lever 3299 and put the poly V-belt on the tension roller and the generator (if you are installing an old poly V-belt, follow the direction of movement indicated on it);
• release the tension roller with lever 3299 so that the poly V-belt is tensioned.
