The timing belt happens to be one of most essential elements of an automobile. However, in the event that it is not taken care of, the breakage of a belt could induce irreversible engine malfunctions. Everyone knows that you have to change the timing belt, on a Volvo 780 or on any type of car. In order to fully assimilate the subject, it is necessary to go around the question about the timing belt: what it is for, why to change it, when to change it, and finally how to change it. You will find our special timing belt article below!
What is the purpose of a timing belt on a Volvo 780?
In order to know the function of the belt of any Volvo 780, you are going to have to understand what the famous distribution. In fact, distribution is the totality of mechanical parts which directs the admission phase (the valves) of the air-fuel mixture, But also exhaust. This timing belt is a toothed belt, carried away by the crankshaft pinion, which in turn encourages the pulley camshaft. Depending on the styles of cars, it may also call the pulley of the injection pump but also the pulley of the water pump in most of the engines. Basically, it is the timing belt that will allow to drive the pistons and various engine parts so synchronized.
Why change the timing belt on a Volvo 780?
Thanks to its consistency in caoutchouc, the distribution belt will wear out over time. If you drive a lot, the walking belt becomes much less malleable and less resistant. This phenomenon becomes more and more important if you drive in urban areas, with frequent starts. If, on the contrary, you drive little, the belt may slip. deform if it remains day and night in a stable position. If ever a belt comes loose or comes off, this will cause engine stop immediate. Also, with the contraction, it could damage a number of parts of the system. It is indeed capital to pay attention to it. We will now see when to change it.
When to change the timing belt on a Volvo 780?
The disadvantage of the belt is that it does not necessarily have a wear indicator. It is not easy to assess its wear, especially since it is hardly accessible within the engine. The easiest way to avoid causing engine breakage is to follow the manufacturer's instructions. However, it is sometimes essential to trust the mechanics. It is frequently recommended to change them every 100 000 kilometers, or every 5 years. Some conditions, such as coolant or oil leaks, can damage the belt prematurely.
How to change the timing belt on a Volvo 780?
Replacing the timing belt on your Volvo 780 is not easy. In fact, it is a vital part of the engine, in fact if it is not properly done, this will inevitably produce irreversible damage to the vehicle. This action is therefore not recommended without the presence of a mechanic. To change the timing belt, you must first obtain the distribution kit whole. Here are the phases to be observed in order to be able to replace the famous belt:
- Make sure to loosen the tensioner roller so that you can loosen the belt.
- Release the timing belt.
- Remove all the rollers and the water pump.
- Install the new water pump
- Place the rollers in their respective places
- Add the timing belt in place, respecting the marks
- Tension the belt following the recommended tension using a tensiometer
- Run the engine manually, which equals 4 city turns
Conclusion
It is therefore essential to master several points before starting work. The belt happens to be a essential vehicle component, it is this one that will synchronize various parts. Its inevitable wear means that it must be changed quite often. If you leave too much lying around, it could damage the vehicle irreversibly. And finally, it is essential to have excellent mechanical skills before starting this kind of practice. It's done, the key is in your pocket. Good road !
