Concerning castors, we should know that there are tension rollers that pull the chain and idle rollers, or fixed castors, which are required for suppression of idle oscillations. Sometimes they are also called chain or belt dampers, because of their function. This element is installed when you need to secure the belt configuration on the main lead and driver pulley for several reasons: for example, to increase the contact area between the belt and the pulley, as well as to provide the bypass of the belt around the protruding element.
Concerning the timing belt tensioner of the gas distribution mechanism and the chain guide, the most important is the fact that the chain or belt that drives the gas distribution mechanism ensures a very well transmission of motion, meaning, they must not hang out or slip. The fixed castors perform this function. They are necessary in order to correct the direction of the belt motion. These rollers do not rotate the belt or the chain. Their purpose is to push them aside, to press them tightly against the gear, as if to fix the item.
An important factor in the excellent performance of the rollers is their compatibility in size and durability, as the belt rotates at high speed.
If you have the necessary tools and you have already changed parts on your car, than you will be able to replace this part by yourself. First, you need to unscrew the fixed castor (idle roller) bolt in the counter-clockwise direction. Remembered that the fixed castor bolt is quite long and, on the last turns of the thread, the roller props on the key that holds the belt tensioner. In order to completely unscrew it, just dispose the axle play of the roller. After that the item should be replaced with a new one.
It should also be mentioning that the gas distribution mechanism is an important junction, so replace the worn out part with new one and of high quality. To do this, please contact our online store where you can buy various auto parts such as nozzles, sidewalls or the timing belts at affordable prices.
