Timing belt vs timing chain: which is better?
First, we need to know what these two different mechanisms do for our car. It’s simple, they both perform the same function which is to synchronize the rotation of the crankshaft and the camshaft(s) so that the engine's valves open and close at the proper time. They both operate in the same way and the only difference is their shape and the materials they are made of. The question is, which is better?

Timing belt or timing chain?
This is one of the most common questions when buying a car nowadays. It is no longer a question of comparing a timing belt with a timing chain, but to understand the quality of the engines on both sides. Why is that? The short explanation is that the technology has advanced and modern engines work better with one system or other. The issues can come from the engine, not from the chain or the belt itself. At least, in most cases.
Which is better- timing chains or timing belts
The question of "which is better?" can never be answered. Both systems are permanently being further developed. For some time now, vehicle manufacturers have been moving away from chains again because the friction loss with chains is too great. There are many options.
Why choose a car with a timing chain or a belt?
The customers used to decide whether they prefer a chain or belt before purchasing. However, the actual concern should not be about the timing system, but in the countless tasks that we ask an engine to perform. It is recommended to investigate the engines of the cars we are interested in and check for any possible damage. Both systems are equally distributed globally so there is no so-called “winner” between them.
Timing chain replacement
Originally, or rather back when engines were built with sturdy chains, these chains lasted forever. In today's downsized engines, things look different. The chains do not have a replacement interval specified by the manufacturer, but they often have to be replaced quite early because the weak chain has elongated (sometimes already between 60.000 and 80.000 km).
In contrast, the timing belt has proven to be much more durable. In comparison, the replacement intervals for modern timing belt engines have been greatly extended (to 240,000 km - 300,000 km) due to further development and new materials.
Timing belt replacement
Like the timing chains at SKF, we provide timing belt kits as well. SKF introduced the timing belt kit concept to the automotive aftermarket over 30 years ago and continue to pursue the best products to offer our clients.

FAQ
Does my car have a timing belt or a chain?
The easiest way to know if your engine has a chain or a belt system is to take a quick look at the engine. If it has plastic covers on the front, it runs a timing belt because the timing belt runs dry and does not need more protection. However, if it has a sealed metal cover (to prevent the engine oil from leaking) then it is a chain system.
What are the signs of a bad timing belt?
There are some signs that indicate damage to the timing belt. Therefore, the synchronous drive should also always be checked for signs of wear during maintenance. As a driver, it is very difficult to hear damage to the timing belt, as the engines on modern vehicles are very well soundproofed. We want to avoid having breaks in the timing belt for several reasons. A broken timing belt can kill your engine and the cost of repairs can be very high. If your car has a lot of kilometers on it, you should watch for signs.
Can I replace the timing belt myself?
As with everything in a car, it is possible to do the work yourself if you have some advanced knowledge of mechanics. If you do not have the advanced knowledge, it is recommended to have it done by a professional who has the right tools and experience to do the job.

When replacing a crankshaft seal, mechanics often find that the shaft surface is too worn for a proper seal, leading to persistent oil leaks. In the past, the only solutions were either replacing the crankshaft—an expensive and time-consuming process—or re-machining the surface, which required specialized tools and additional labor. Fortunately, there is now a simpler and more cost-effective solution: SKF Speedi Sleeve.

For a steer axle with a 12,000-lb. rating, commonly-accepted pressure is 110 psi, and most drivers assume 85 psi is okay. But for every 10% of underinflation, you’re looking at a 1% reduction in fuel economy. Multiply that by the miles you travel in a year and you can expect:

In the engine, what allows the correct synchronization between the crankshaft and the camshaft is the timing system. This movement is produced by one of two elements: a timing belt or a timing chain. In this article, we tell you which components are included in the SKF timing belt kit.
