Most U.S. aftermarket manufacturers use an English measurement system, where the length is expressed in tenths of an inch, but the worldwide industry standard is based on a metric measurement. This metric numbering is sometimes referred to as a “PK” number, and is found on most belts along with the manufacturer’s traditional part number.

Modern timing belts are constructed of rubber, synthetic rubbers like neoprene, polyurethane, or highly saturated nitrile, with high-tensile strength reinforcing cords made of Kevlar, polyester, or fibreglass.

With the continuous development of automobile industry, the noise problem of automobile transmission has been paid more and more attention. Among them, the transmission belt noise is one of the common problems.

Motorcycle riders have three driveline options when selecting bikes: chain, shaft, and belt. Each of them has different maintenance requirements, so riders are encouraged to explore the pros and cons of each and why belts are popular with Harley-Davidson owners.

It’s all too common to see a pair of sprockets connected through a chain, driving the rear wheel of a motorcycle. However, it’s not the only final drive system used on motorcycles. Belt drive and shaft drive are the other two final drive systems, though they are not as ubiquitous as chain drive systems.

There are various arguments about the advantages or disadvantages of each one. The discussion of power loss is for another day, though (spoiler alert) I think the rumours without evidence of high power losses of some final drives are greatly exaggerated.

For some time now there has been a trend in the bike industry toward speccing a belt drive, rather than a traditional chain, to bikes in certain categories. You might land here wondering ‘what is a belt drive and do I need one?’.

Motorcyclists commonly drive their rear wheels with sprockets coupled to a chain. Although it is one of the motorcycles' most popular final drive systems, it is not the only one. Two other final drive systems are belt drive and shaft drive, although they are not as widespread as a chain.

Which of the three primary drivetrains—chain, belt, or shaft drive—is better, is one of the most often asked issues in the motorcycle world. There is a reason why bikes have different types of drivetrains; it is obvious that all motorcycles on the market have undergone significant R&D from the manufacturers.

Well, what exactly is this solution anyway, and does it make any sense on a bicycle, and if it does, in what way? We'll try to give you a bit of an insight into the history of this invention. We'll also tell you what it's suitable for and whether it's possible to install a belt drivetrain on your bike at all.

Electric bicycles are becoming increasingly more sophisticated, as highlighted by the rise of belt drive technology in both affordable and top-of-the-range models. These e-bike belt drive systems are quickly replacing the messy, greasy metal chains and becoming the new norm. But are they actually better?

The most common drive system uses a chain to drive power to the wheels. This drive system has been in use for at least a century. Most bicycles, electric bikes, and motorcycles use chains, and it may be the only kind of drive system you have personally seen.

(Changing topics this time, the following is my response to an inquiry by a Harley rider as to expected belt drive system life on his H-D motorcycle.) Before answering your question, I need to mention that the condition of the 32-tooth transmission output sprocket controls belt life to a much greater degree than the 70-tooth rear sprocket.

A cambelt or timing belt is one of the most important parts of a car's engine. It's responsible for keeping crucial parts of the motor working in sync with each other - making sure timing is accurate to ensure perfect running.Some cars have a timing chain instead of a belt. A chain is normally made of metal links rather than rubber or polyurethane, which is what most belts are made of. Chains tend to more durable and normally last longer than a belt, but that's not to say some can fail.

A timing belt also known as a cambelt, is an essential part of your vehicle’s engine. In this article, we’ll discuss what a timing belt is, what it does, what to do if it breaks and when you should replace it.

Timing is everything. For jokes, music, cooking, dating—even engines! That’s because your car’s engine relies on a timing belt to stay in sync. The timing belt makes sure everything in the engine is operating smoothly, keeping you safe on the road.

The cam belt, or timing belt, is an essential component of your car’s engine. But what does it do, when does it need replacing and what happens if it breaks?

engine's operation that its failure is often catastrophic - meaning, not only does your vehicle suddenly not run, the internal engine is likely damaged. It is one of those parts that as much as the replacement is painful as routine maintenance, choosing not to perform this maintenance will absolutely lead to a catastrophic failure, and an even bigger bill.

When it comes to getting your timing belt replaced, most car owners often shy away and try to postpone the task because it’s on the expensive end in terms of repair and maintenance. Avoiding timing belt replacement can be a huge mistake, however, as failure has the potential to cause serious damage to your vehicle’s engine. A broken timing belt can render your vehicle inoperable, or even worse, bend your valves and pistons causing major damage to your engine.

You can quickly recognize a timing belt because it looks like it has a set of teeth running along its entire length. A timing belt keeps the camshaft and crankshaft turning at the correct rate.
