![]() ![]() While this issue can cause serious problems for your machines, it is typically a quick and simple fix. In some instances, an unsecured pulley bracket can even force a timing belt off the path. Keeping the pulley in place, this bracket can become warped or loosened over time, causing the pulley to wobble as it moves. If you’ve reviewed all the previous symptoms and found your pulley to still be in good condition, there’s one final component of a timing belt pulley to consider – the holding bracket. What if the Pulley Seems Fine, But There’s Still an Issue? If you do decide to try this test for yourself, be sure to always use caution, and ensure the machine is completely turned off during the entirety of the process. If you find the pulley has any resistance, it will likely need to be replaced. You can check for this specific issue by taking your belt off the pulley in question and attempt to spin it by hand. When this happens, the rotation of the belt on the pulley can be completely interrupted, leading to a wide range of problems, such as overheating, stalling, torn belts, and more.ĭamaged pulley bearings can cause the pulley to freeze completely, preventing the belt from moving properly. In a worst-case situation where an issue has been ignored for a long time, your timing belt pulley, and the bearings within, may wear out to the point of cracking or even a complete breakdown. In most cases, this is an indication that you will need a new pulley, and perhaps even a new belt, depending on the damage caused. As a result, the belt can come loose and knock against other components, causing a slapping-like noise. When pulleys wear out, they often struggle to maintain tension on the belt. Speaking of warning noises, another common sign of a bad timing belt pulley is a knocking or slapping sound coming from your machine. Additionally, as the issue begins to worsen with continual wear, a bad pulley can bind or slip, causing the belt to emit a similar noise when the engine is first started. What causes this sound?Īs the surface of the timing belt pulley wears, or if your pulley is seizing or binding in any way, it can cause engine belts to squeal from the friction of belt rubbing against pulley. ![]() Think of this sound as an alarm bell signaling a need for repair or replacement. Belt “Squealing” or “Whining” NoisesĪ common warning sign of an issue with your timing belt pulley is a high pitched squealing sound coming from the belt. As the pulley and belt continue to wear down further, there will eventually be a point in time where tension is reduced on the belt, leading to slipping and the improper functioning of your equipment. While your pulley may not need immediate replacement as a result of these marks alone, it is another good warning signal that the life of your pulley may be coming to an end. Visible signs of wear can take the form of marks on the surface of your pulley caused by the friction of the belt. As that wear continues to develop, one of the first and most common symptoms of an issue with your equipment will be visible wear on the pulley. Over extended periods of use, both the timing belt pulley and the timing belt itself will begin to wear out. While not an end-all validation of a bad timing belt pulley, it can be the first indication of some sort of issue which must be addressed. If your setup is wobbling or not moving as smoothly as it used to, it may be an indication of deterioration and the need for a replacement part. When determining the condition of your timing belt pulley, a potentially simple way to begin is by reviewing how the belt and pulley system are functioning. Shaky, or Otherwise Incumbered Belt Motion With that being said, here are a few of the most common symptoms you can use to determine the condition of your timing belt pulleys. While it’s not always easy to determine exactly when these pulleys need to be replaced, there are a few key symptoms of a bad timing belt pulley you can keep a lookout for. However, because these components undergo such a high and repetitive level of strain from daily use, they tend to wear out relatively quickly and must be replaced on occasion. ![]() From manufacturing equipment to our vehicles, much of the machinery we use daily heavily relies on properly functioning timing belts and timing belt pulleys. ![]()
