Schemes for laying the poly-V-belt on a car without air conditioning and with air conditioning are presented on (pic. 156) And (pic. 157) respectively.
Withdrawal V-ribbed belt is performed as follows:
- mark the direction of travel 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 (pic. 156 and 157) loosen the tension of the V-ribbed belt;
- remove the V-ribbed belt from the power steering pump drive mechanism;
- remove poly V-belt;
- Check the condition of the V-ribbed belt. It must be free from cracks or breaks, peeling of coating or fibers, frayed fibers, frayed or glassy side surfaces, oil or grease stains;
- A damaged V-ribbed belt must be replaced without fail.
Installation V-ribbed belt is carried out as follows:
- turn the tension roller with the lever 3299 and put the V-ribbed belt on the tension roller and generator (if an old V-ribbed belt is installed, follow the direction of travel indicated on it);
- release the tension roller with lever 3299 so that the V-ribbed belt is tensioned.
