What else can replace timing chain?

Timing belts have replaced timing chains and are on many of today’s engines. Both belts and chains ensure that crankshaft, pistons and valves operate together in proper sequence. Belts are lighter, quieter and more efficient than chains.

Do modern cars have timing belts or chains?

As the modern car engine became more complex so did the timing belt and timing chain configurations. To make small engines perform like sports cars, variable timing and twin overhead camshafts are used. On the bright side, timing belts are changed every 90,000 to 100,000 miles now.

What is the greatest advantage of using a timing belt instead of any other timing drive?

High mechanical efficiency, as much as 98\% when properly maintained. By contrast, chain drives are in the 91-98\% efficiency range, while V-Belts average in the 93-98\% range.

Is timing gears better than timing chain?

A gear driven system will always be much more stable, accurate, and last longer than any belt or timing chain, even a double-timing chain setup. The disadvantage to it is that they are typically noisy, require more lubrication than other methods and adds more overall costs to other motors designed without it.

Is a serpentine belt the same as a timing belt?

Timing Belt. Don’t get confused—a serpentine belt is not the same thing as a timing belt. The timing belt is located inside the engine and keeps the crankshaft and camshaft in sync. This ensures that the engine intake and exhaust valves open and close in time with the pistons so the engine runs smoothly.

Can I replace timing belt with chain?

A timing chain runs inside the engine, as it needs to be lubricated by the engine oil. A timing belt typically needs to be replaced between 40,000 and 100,000 miles depending on the vehicle. It’s a few hundred dollar repair. A timing chain doesn’t need to be replaced unless there is a problem with it.

What is the disadvantage of using a timing belt?

Disadvantages of timing belt drive They are not economical. Need a sophisticated design of the belt as well as the pulley. Clutch action not possible. No protection against overloading.

Is a chain better than a timing belt?

Most automakers recommend replacing the timing belt every 60,000 to 105,000 miles. Timing chains are heavier and more complex than timing belts, but they also last much longer. Really, unless there’s a problem, timing chains don’t have a replacement interval.

Does Geardrive add horsepower?

However, gear drives create more friction than a chain or belt drive, which may take a bit more power to drive the cam. Most of these tests have found very little difference from one cam drive setup to another, usually no more than a couple of horsepower difference.

Why don’t timing belts work with chains?

The reason for this is quite simple: chains are made from metal, whilst timing belts are made from rubber, which simply isn’t as strong. That isn’t to say timing belts are weak, but they will likely need replacing at some point, whereas a chain can last as long as the vehicle itself does.

How much does it cost to replace a timing belt?

While the parts cost is low, the labor cost to replace a timing belt isn’t. Timing belt replacement is not a DIY job so expect to pay anywhere from $300 to $1,000 for the job which usually includes replacing the water pump as well. Like a timing chain, if a timing belt breaks, catastrophic engine damage can occur.

How long do timing chains last on a car?

In fact, most timing chains will last as long as the car itself. This means you can easily get between 150,000 and 200,000 miles out of a timing chain. This is at least double the amount of usage you can get from a timing belt even though the timing belt was invented after the timing chain.

When was the timing belt invented?

Timing Belt. About 50 years ago, the timing belt was invented for vehicles. It was an alternative to the timing chains which currently existed. The benefit of a timing belt is that they operate more quietly and are very strong.
