Replace a Spare part Tensioner Pulley – a defective one or if the limit of use has been already reached. Find out useful information about Tensioner Pulley

This belt drive component is located on the floating axle. It is necessary to maintain the belt tension and to increase the angle of contact of the small pulley. The roller is used for gears with small axle spacing, large gear ratio. It is required to be installed near a small pulley on the slack side. The disadvantages of the installation of this component are additional belt bends, which lead to reduction of its durability. V-belt tension roller is installed on the generator and air conditioner. If car owners hear rustling sound when the motor is running, this means that it is quite dry and needs replacement.

Another indication for roller replacement is belt replacement, which is required for drive of the VVEL. If you want to replace only the roller, it is not necessary to remove the timing belt. It should be noted that during any maintenance it is necessary to check the degree of tension of the timing belt. It is necessary to adjust the tension if belt is strongly or weakly stretched. When the belt is slightly stretched, the belt’s teeth break down. Also, because of improper timing belt tension, the belt can jump on the timing pulley of the crankshaft and camshaft. And this could lead to malfunction of the valve timing installation and loss of engine power. A significant belt jumping can result in its total damage.

After you determine the cause of fail, you need to buy a new spare car part: tensioner pulley, timing belt or camshaft. Do not hurry to buy the part in the service centre. To save your time and money order the necessary car part in the online shop. To do this you need just to have PC and Internet connection.
