Issues with timing belts are one of the leading causes of breakdowns.
Cam belts can suffer a number of problems and spotting them early on can prevent serious trouble.
The timing belt snapping all together is obviously the main concern, but there are other issues that can lead to this happening.
Cam belts can become too tight resulting in them becoming noisy and emitting creaking noises.
Should the teeth fall out of your timing belt this also spells disaster as the camshaft will not be turned.
The camshaft will also be stopped from turning if the timing belt is not aligned properly.
Timing belts can also become damaged by oil being compressed into the belt changing the size of the belt, meaning that it will not work correctly.
Timing belts can sometimes loosen which can in turn lead to them slipping out of position.
Cam belts can sometimes break after becoming corroded.
A cam belt provides a connection for the crankshaft of an engine and its camshaft.
It is covered with teeth that vary in shape depending on the sort of belt your vehicle has.
Timing belts that are new will have rounded teeth, whereas triangular teeth tend to cover traditional belts.
Cam belts will be often made out of rubber and are then strengthened by materials such as fibreglass so that they can last longer between replacements.
Cam belts made recently tend to be made from resistant materials like HSN to prevent damage as a result of exposure to high temperatures.
Modern cam belts are not as wide as there predecessors in order to decrease weight and friction subsequently.
Timing belts are belts, normally made out of rubber that are able to control the timing of valves in engines. Engine valves open and close a specific number of times and the cam belt makes sure that this happens in order. A cam belt's teeth are carefully designed to perform effectively for the intended engine.
These teeth turn the cam shaft of the engine and make sure that it stays synchronised with the crankshaft. The camshaft turns at half the speed as the vehicle's crank shaft, and this is enabled by the timing belt. Should this be prevented from happening the engine will not run properly which will lead to serious engine damage.
Causes of such damage to engines can be your engine's valves remaining open when they shouldn't be resulting in them being stuck by the engine's pistons.
There are a number of different types of timing belt and the sort that you will need to have will depend on the type of car it is that you own. There are two different types of engine that need a timing belt.
Cam belts for interference engines require careful maintenance because of the proximity between the valves and pistons in the engine of your car. Non-interference engine cam belts do not need such a high level of maintenance as the pistons and valves are spaced further apart.
There are also timing belts with varying shaped teeth. The teeth in cam belts that are older are often triangular, whereas timing belts with rounded teeth are found in more modern vehicle.
Timing belts tend to be made from rubber imbued with another material such as fibreglass to strengthen it, although more and more timing belts are made from modern materials such as HSN.
