timing chains

Timing chains should be inspected. Belts or chains are the long components that attach to the teeth of the crankshaft and the camshaft and connect their relative movements so that the engine can work in perfect harmony. They are essential components of any motorized engine. Even though both of them serve the same purpose, there are notable differences between them.

Types of Timing Chains

If you go out looking for timing belts, you will find that they do not differ from each other a great deal. On the other hand, you can find two different types of timing chains. One of them is a silent chain and the second is the roller chain.

As the name suggests, the silent chain cancels out a good deal of noise from the engine. The chain and sprocket assembly and workings involve frictional movements that contribute to plenty of noise, and silent chain application can help reduce the levels of noise from the engine.

Silent chains are very common and you can find them on many engines. Manufacturers love them because they are simple and cheap to manufacture. These timing chains consist of multiple links that fit into the teeth of the sprockets and spins them into motion.

The roller chains have rollers that rotate according to the movement of the sprocket. This in turn helps reduce friction, parasitic horsepower losses, and localized wear on the chain. Roller chains are more expensive than silent chains because of their advantages; however, they are noisier than silent chains. You can also find two different types of roller chains, single and double roller chains.

Dual rollers are stronger and offer more durability; however, it generates more friction because of its larger surface area. Since roller chains have more surface area, they also require more oil, and in turn, they often have problems with oil contaminants.

Timing chains and Oil

Unlike timing belts, chains need oil lubrication. This is both the strength and weakness of timing chains. It is a weakness because the oil inside the chain can vary, and many times, it is the reason for premature chain failure.

The quality, viscosity, and replacement of chain oil can shorten the lifespan of a timing chain. However, with good maintenance, and good quality oil, the chains can be better options than belts since they are more durable have a longer time interval, and there is a low probability that they snap.

Both timing belts and timing chains can offer a smooth driving experience. However, timing chains are more cost-effective option than belts since they can last you the lifespan of your engine without replacement.
