Timing Belt Pulleys: What Are They and What Can You Do With Them?

Timing Belt

If you drive a car, do you know about timing belt pulleys? This important feature helps you get from one point to another.

Without this system, you won’t make it to your destination. Read more to learn why this pulley is so important.

Timing Belt Pulleys

Inside your car, there is a lot more than just the engine. So many parts inside have to work together at the same time.

For example, your engine holds a timing belt pulley. This system works to help open and close the valves at the exact time they’re needed.

This system is connected to the crankshaft and the camshaft. The timing belt has teeth that lock onto the shafts to move.

A bicycle is a perfect example of seeing this work. The chain is connected to the front and the back of the bike to make it move. This is the same thing happening inside of your car engine.

If you’ve experienced problems with your bike chain, you were able to recognize something wasn’t right. Unfortunately, this is the same thing that could happen inside your engine.

When this system is performing correctly, it allows for the engine to open and close different vales at synchronized timing. The timing is what is important for your car to run.

Using Timing Belt Pulleys

These pulley systems are used anytime two shafts need to move a belt. The belt should follow a pattern by being attached to shafts. These shafts have teeth that keep the belt in place.

If the teeth of the belt are not going into every groove on the shaft, this can result in slipping. This would mean the timing belt is worn down or can no longer perform.

Without the teeth, the belt would continuously slip off, and only one shaft would be in use. This would disrupt the continuous flow of the shafts. You’ll need pulleys and sprockets to ensure the engine is performing appropriately.

When to Replace

Like many other parts of a car, the timing belt and pulley may need changing. How do you know when this needs changing?

The first sign is a simple check engine light. This is an easy indicator something inside of your engine isn’t working.

If you start to hear a knocking noise, this means your timing belt and pulley may be hitting the timing cover. This is an indication it is slipping and no longer staying in place.

The timing chain can be loose and you might hear a grinding noise. This is from the pulleys grinding on each other instead of relying on the timing belt for a smooth process.

If the timing belt is completely missing, you may not be able to start the car at all. For it to run, the belt must be operating the pulleys. Without it, the car cannot run.

Expand Your Knowledge

Timing belt pulleys can cost you money if they aren’t performing as they should. You can now recognize some signs of your belt slipping or missing from your engine.
