In order for the additional devices of the vehicle to cope effectively with all the assigned functions for a long time, they need torque from the power plant, due to the camshaft, which is connected to the crankshaft. It should be noted that the transmission of torque from the camshaft directly to the rollers of the workover is carried out thanks to belts or timing chains. However, it is important to understand that the chain, unlike the belt, does not stretch even after a long time. However, it still needs to adjust the tension force from time to time. Only in this case is an excellent and uninterrupted operation of the entire gas distribution mechanism achieved.

The functionality of the chain tensioner

The INA brand Tensioner, timing chain is an extremely important and necessary device, without which the chain itself is not capable of performing the assigned tasks. The thing is that over time, the tensioner becomes unusable, as a result of which it needs to be replaced. However, in order to find the perfect spare part, it is imperative to build on the individual characteristics of the vehicle. Only then can you count on the new timing belt tensioner to meet fully your needs and wishes.
