The belt is taut because of tension rollers, holding spring. Installed damper prevents vibration of the belt. In Fig. 141 shows the individual parts of the tension of the belt drive mechanism. Tension rollers interchangeable among different models. In the basic configuration without additional units installed tension roller is equal to the width of the other pulley grooves. In other versions of the roller surface is smooth. This must be considered when replacing. In Fig. 142 shows the entire tensioning mechanism. To access it, the front of the engine must first be dismantled. Belt drive must be checked every 20 000 km. To do this, put a chalk mark on the belt in an accessible place. Crank the engine starter for at least one turn. To avoid starting the engine to push the screwdriver to lever off the fuel pump. Scroll starter engine, inspect the entire length of the belt until the marks made. Cracked, worn or scorched places indicate the need for replacement. For removal and installation of the drive belt, proceed as follows:

|
- Loosen the nut of the tension lever 1 (Fig. 143) and insert the rod into the tensioning lever mechanism, as shown in Fig. 144. As the rod can be used, for example, metal bars with a diameter of 12 mm and a length of 180 mm; - Press lightly on the rod to the left side, to press the bolt; - Now click on the little bar to the right, easing tension spring; - Press down the tension roller, to be able to remove the belt. Belt installation is carried out in the reverse sequence. Please hold the strap through the tensioning roller, then successively put on all of the pulleys. The last thing the belt is worn on the water pump pulley. If the work has been done properly, the belt is installed under tension. Removal and installation of the mechanism of the tension is performed in the following sequence: - Release the front of the engine to access the details of the mechanism; - Remove the drive belt as described above; - Remove the tensioning lever 5 (see. Fig. 142) of the spring and the spring 6. When assembling the spring to establish a color mark-up;

|
- Unscrew the damper from the cylinder head (Fig. 145); - Remove the plug 15 (see. Fig. 142), and unscrew the bolt 1 tensioning arm 13. When loosening bolts 14 press the tensioning lever in the direction against the cap. Before installing, thoroughly clean the back of the bolt thread on the thread of the bolt 1. 1 Apply sealant. Before installing the tensioning lever on the bolt 1 lubricate the space between the bearing arm bushings; - Tensioning lever 13 with the damper 2 remove the tension roller 9. Do not lose the washer 12; - Disconnect damper 2 of the tension lever 13. When replacing the damper must be vented several times by clicking on the stock. The damper is installed rod down, as shown in Fig. 142; - Remove the cover 11, unscrew the screw 10 and remove the tension roller 9 to the tension lever 13. Assembly in reverse order with the following tightening torque (Nm): - A tension roller to the tension lever - 30; - Tensioning lever - 100-110; - Damper to the cylinder head - 21; - Damper to the tensioning lever - 20; - Tensioner arm to the head unit - 21.
