Tensioner is a device to tension the V-belt. Specifically we speak about the arm to adjust the tension on the support roller. As a rule, both car parts are sold together and named tension pulley. In order the V-belt’s tension to be optimal it should be under a slight pressure. While all other rollers of the system are fixed, the tension roller can be adjusted with the help of the tensioner. Due to this it is possible to optimize the belt running.
Normally, tensioner and support roller can be replaced individually. The majority of the tensioners used today are semiautomatic. This means that the primary stress is adjusted, for example, when the belt becomes longer because of the wear. If the regulator does not work semi automatically, it must be adjusted manually with the help of the tensioner. If the V-belt is slipping or running unevenly, the reason for that may be defective tension roller or tensioner.
In majority of cases it is necessary to replace both car parts. As we speak about an extreme accuracy, all repair works should be done in a repair shop. An improperly adjusted V-belt can break and result in a bigger harm, for cylinder head gaskets for example. Buy a high-quality tensioner in our online store and you will save on repair.
