What makes pulleys so important?

A pulley is a simple tool that makes it easy to lift or move heavy objects. There are many uses for this tool, but let’s take a look at their mechanical advantages. There are several types and many applications, along with their benefits and costs. So what makes them so important? Read on to find out! Below are some of the most common uses for pulleys. Let’s dive into them.
pulley

Mechanical advantage

If you’ve ever used rope and pulley systems, you’ve probably noticed their usefulness. A 3:1 mechanical advantage system is like a 300-pound load being moved one foot up by three feet of rope. Then you can imagine using the same rope to get into a small space. The same principle applies to limited spaces, and a simple mechanical advantage system is just what you need for this purpose.
Assuming frictionless bearings, a single movable pulley can have two mechanical advantages. It is attached to a heavy object and requires the pulling force exerted by the jack to lift the heavy object. However, when you use a compound pulley, the force exerted on the rope to lift the object changes direction. The three factors used to measure machine efficiency are force, distance, and relative motion.
The mechanical advantage of the pulley is that it reduces the effort required to lift weights. When the rope is attached to the two wheels, applying a force of 500 Newtons can lift a mass of 100 kg. This mechanical advantage is why two rings in a pulley are better than one. Therefore, using a pulley system will save you energy. You can also use branches instead of ropes and pulleys.

type

There are several different types of pulleys. They can be simple or complex, depending on how they are connected. Simple pulleys have a grooved wheel on one end and are attached to an axle. These pulleys are used to lift heavy objects. They are often found on sailboats, and you can even see them on construction sites. On the other hand, stationary pulleys are attached to stationary structures, such as flagpoles. Fixed pulleys can also be used to lift loads from trucks or trains. Pulleys are also commonly used in wells.
Fixed pulley systems use rollers or single wheels. These pulleys are usually made of nylon or wire rope. They are used in heavy duty applications. They are also used in electric motors. A “V” pulley requires a “V” belt to transmit power. Some of these pulleys have multiple “V” grooves to reduce the risk of power slipping. Once installed, fixed pulleys are suitable for many applications.
Simple pulleys are simple pulleys. It has a pulley mounted on an axle and a rope at one end. Rope can be used to pull objects, while plastic pulleys can carry lighter loads. There are two main types: heavy duty and simple pulley systems. In either case, their function is the same: they change the direction in which the seat belt is fastened. So when comparing the two, it’s easy to decide which one is best for you.

application

Pulley systems are simple machines used for a variety of industrial and mechanical tasks. Its design parameters and benefits have improved over the years, but they remain essential for many applications. Let’s take a look at some of the most common applications of pulleys. The applications for pulley systems are endless, from construction to mining, from transportation to packaging. Read on to learn more!
Pulley systems are often used to lift large objects, such as blocks, that might otherwise be too heavy to lift. It also makes the exploration process easier by helping people pull heavy objects into place. It is also widely used on sailing ships. Due to its low cost of use and no need for lubrication, it is a practical choice for many applications. It can be used to lift heavy objects and support long ropes.
The pulley system allows you to change the force required to move the object. For example, a two-wheel pulley system is especially useful for reducing the effort required to lift large objects. The mechanical advantage increases with the number of wheels in the system. In addition, the mechanical advantage of a two-wheel pulley system depends on the ratio of the load weight to the number of rope segments in the system.

cost

In most cases, an idler replacement will cost around $150, but the exact cost will depend on several factors, including the make and model of the car. The cost also depends on the type of idler you need and the cost of the OEM parts. Some pulleys are easy to replace at home, while others require specialized tools, such as pulley wrenches. The chart below shows the cost of popular vehicles. Prices are valid at the time of writing.
The diameter of the pulley is also important, this should be about 60% of the diameter of the active pulley. You can also purchase compensating pulleys at factory prices. Be sure to select the correct size before placing the pulley on the machine. Also, make sure you have enough space for the pulleys. Once you have the desired pulley size, you can determine the best type of belt to install.
While this method is the most common type of belt drive, there are other methods of spinning cup blanks directly from a flat metal disk. One such method is described in US Patent No. 5,500,31. US Patent No. 1,728,002 and shows a method of making a dynamically balanced V-groove pulley. Using a headstock die with sliders increases the cost of the pulley. In addition, different cup blanks require different molds.

lubricating

The lubrication of pulley bearings is relatively simple. The pulley itself rotates smoothly with little vibration. Bearing contact loads are relatively low, and well-lubricated pulleys operate near ambient temperatures. Here are some tips for properly lubricating pulley bearings. Make sure to lubricate the nozzle before applying grease.
Check grease, elastic ring, pulley bearing clearance once a year. If the elastic ring of the pulley is damaged or the roller bearing on the associated pulley is damaged, replace the pulley. Also, check the running noise of the pulleys to see if they are making noise. Check the bearing, damage to the elastic ring may indicate bearing failure or roller failure.
Proper lubrication is critical to the life of the rotating pinion. Avoid exposure to sunlight or water. Protects the pinion meshing area from hard impurities. Liaise with crane operators and lubricators during maintenance and lubrication operations. They should know how to avoid pitfalls in the lubrication process. In case of malfunction, please contact service personnel and take necessary measures.

Compound Pulley System

A compound pulley system is used to lift heavy objects. These systems can use ropes or cords of different sizes. In general, the total weight of all ropes must be less than the weight of a single rope. The system can be used in large areas, but may not be suitable for smaller spaces. To learn more about compound pulleys, read on! Here are some helpful tips. 1. Understand the difference between single wheel and compound wheel
A composite pulley system consists of three components: a drive pulley, one or more driven pulleys, and two pulleys. The drive wheels are usually connected to shafts that are connected to the engine or transmission. The driven wheel is a separate unit mounted on the same shaft as the drive wheel. A compound pulley system helps lift heavy loads. These pulleys are the most common type of pulley system in use today.
Composite pulley systems are widely used on construction sites. They save energy by spreading the weight of heavy loads over multiple smaller loads. This means that the elevator does not have to use high-capacity lifting equipment. Additionally, the compound pulley system allows users to easily adjust power distribution to meet their individual needs. They can also use more than two ropes if necessary. This increases the range of motion of the lift arm.

The Mechanical Advantage of a Pulley

A pulley is an important tool for many tasks. The advantage that it offers over a hand-held mechanism is its mechanical advantage. In this article, we’ll discuss the types of pulleys and their applications. We’ll also look at the types of compound pulleys. And, of course, there’s a little bit about the mechanical advantage of a pulley. This article will help you decide whether this tool is right for your needs.
pulley

Mechanical advantage of a pulley

A pulley has a mechanical advantage over a lever because it is able to produce more force over longer distances. The mechanical advantage of a pulley sounds brilliant and could produce energy. But what exactly is this mechanical advantage? Let’s take a look. First, consider how a pulley works. A rope supports a 100kg mass, which requires 500 newtons of force to lift. If the rope supports a 100kg mass, two sections of rope can support that load. Using a pulley, you can lift the same weight with half the force.
A pulley’s ideal mechanical advantage is the ratio of the force applied to the total length of the rope. The larger the radius, the greater the mechanical advantage. A pulley made up of four rope segments has an ideal mechanical advantage of four. Therefore, a four-segment pulley would multiply the force applied by four. As the numbers on the rope segments are smaller than the total length of the rope, it would be better to use a compound pulley.
The mechanical advantage of a pulley can be calculated by using the T-method. The first step in calculating the mechanical advantage of a pulley is defining the force you need to lift. Then, divide that force by two to calculate the amount of force you need to lift the load. Once you know this amount, you can design a pulley to meet your needs. That way, you can achieve the perfect balance between the two types of pulleys.

Types of pulleys

The main function of the pulley is to change the direction of the force. The mechanical advantages of a single pulley are two. Ideally, two pulleys should have two or more mechanical advantages. The mechanical advantage of compound pulleys can be increased to two or more. The number of pulleys that make up the composite pulley will determine the mechanical advantage. Certain types of pulleys are combined in one housing.
A stepped pulley is a set of pulleys with stepped surfaces. Each face is anchored to the mid-axis in an ordered sequence. This design gives these pulleys their name. They are used to increase and decrease the speed of the driven pulley. Step pulleys are usually used in pairs. They can be straight or stepped, but usually come in pairs.
The three main types of pulleys are pulleys, rope pulleys, and chain pulleys. Pulley Pulley systems use mechanics to lift and lower heavy objects. The Greek historian Plutarch credits the invention of the pulley to Archimedes of ancient Sicily. The Mesopotamians used rope pulleys to lift water around 1500 BC, and Stonehenge is said to have been built using a rope pulley system.
pulley

Application of pulley system

The advantages of using a pulley system are numerous. The ability to lift heavy objects is a good example. The pulley system makes it easy for people to lift blocks and other large objects. It can be used in many different applications, from utility elevators to construction cranes. In addition, it is widely used on sailing boats. If you want to learn more about the benefits of a pulley system, keep reading!
You can use the pulley system to water flowers or water plants. Some of them even lowered the pot to make cleaning easier. Pendant lights are another great place to install a pulley system. Climbing and fishing are just some of the activities that utilize the pulley. They are great for fishing and gardening. And since they are so versatile, you can use the pulley system anywhere.
To get the most out of your pulley system, you must choose a product that has all of the above attributes. A high-quality pulley must have a large pulley diameter and be made of sturdy materials. The cables must also be properly supported in the pulleys to ensure a long service life for your investment. A good cable should have minimal cracks and be lubricated. These factors are the most important considerations when choosing a pulley system for your needs.

composite pulley

Composite pulley systems combine two or more movable pulleys. These systems maximize the force to move the weight and can also change direction so they can be used to lift weights. Composite pulley systems can be as simple or as complex as your needs. For example, a pulley pulley system uses multiple pulleys on each axis. This method is often used for hoisting building materials.
A compound pulley system has two or more rope segments, each of which is pulled up on a load. It can increase lift by making objects move faster. These systems are common on large sailboats and construction sites. Composite pulleys are also available for larger boats. Due to their versatility, they are versatile tools for construction sites and large sailboats. If you have their app, you should consider buying one.
The main advantage of composite pulleys is their versatility. You can use them to lift weights or use them to save energy. Composite pulleys are especially useful for lifting heavy objects. For example, you can tie a paper clip to the end of the rope and pull it up. The flag is then lifted into the air with the help of compound pulleys. Composite pulleys are a great invention and they are often used in construction.

security considerations

There are several safety considerations to consider when using pulleys. The first is Secure Workload (SWL). This value is a general guideline for the maximum weight a pulley can safely handle. It varies according to the height and angle of the pulley. Besides SWL, there are some other factors to consider. Consider each one before deciding on the pulley that best suits your needs.
Another safety consideration is the weight of the load. Since the highs of the pulley are higher than the lows, it doubles in weight. The weight of the high point should not exceed 4 kN. The safety factor is calculated by multiplying the strength of the pulley by the weight of the load. Secondary COD has a safety factor of 10:1 and bulletproof primary anchors should be used with pulleys.
If using a chain hoist, you must be trained in the appropriate type of lifting. It is important not to hang on the top hooks of the structure, nor to overload or rig the hooks with multiple slings. You should also avoid corroded or damaged chains, as they can cause the crane to jam or overload. A worn chain can even cause the load to drop.
pulley

Components of a pulley system

Proper design of the pulley system can increase the life of the cables and pulleys. Larger diameter cables should be selected as they are more durable than smaller diameter cables. The cables should also be supported in the pulley grooves. The pulley must be designed to be compatible with the cable and its lubrication should be optimal. Proper lubrication of cables and pulleys will ensure maximum durability and longevity.
The first type of pulley is called a fast pulley. These pulleys are used for quick start and stop of the machine. These pulleys are usually mounted in pairs on the countershaft of the machine. One pulley is tightly mounted on the machine shaft, while the other pulley is fitted with a free-spinning mechanism. When the machine is running, the belt is mounted on the tensioner pulley, and when it is stopped, the belt slides on the independent pulley.
Composite pulley sets reduce the overall effort required by reducing the size of the pulley. These are usually attributed to Archimedes. Flat pulleys are often used in flat belt driven transmission systems. These are used in high-speed, low-power applications. Flat pulley idlers are also used on the back of traditional V-belts.

Overview of Different Types of Pulleys

A pulley is a wheel mounted on a shaft or shaft. Its purpose is to facilitate the movement or change of direction of the cable or taut rope, and to transmit power between the cable and the shaft. Pulleys are typically used for lifting, winding or forklift applications. If you are building your own pulley system, the following design and installation considerations should be followed. This article will give you an overview of the different types of pulleys.

Pulley System Mechanics

There are many different ways to utilize the mechanism of the pulley system. The most basic pulley system consists of a fixed wheel and a support frame. Both components are connected by ropes or cables used to support the load. A pulley system is effective when the force required to lift the load is less than the weight of the object being lifted.
One way to use a pulley system is to suspend a block with a mass of 0.80 kg on a fixed pulley. Then another person can hang a bucket weighing up to 40kg. The weight of the bucket is transferred to the fixed pulley. The rope is attached to the pulley by a loop or sling. The rope will spin and pull on the barrel or block.
The pulley system is also an important tool for lifting heavy objects. Pulleys are often used in construction equipment to make lifting heavy objects easier. Gun tackles, yard tackles, and stationary tackle systems are common examples of these devices. They use the mechanical advantage of the design to guide the force that lifts the object. If you want to learn more about pulley systems, visit Vedantu. This website will provide you with a full description of the mechanism and its application.

Types of pulleys

Many different types of pulleys are used to lift heavy objects. They change the direction of the force and are an integral part of the cable system. Therefore, pulleys can move large and heavy objects more easily. However, before buying a pulley, you should have an idea of ​​the benefits it brings. Below are some of the most common uses for pulleys.
Conical Pulley: Consists of several small conical pulleys connected to each other. The larger base of one pulley is used to guide the force. Round pulleys are used in the same way as step pulleys. They are widely used in industry and can be purchased at any hardware store. Pulleys are a huge investment, and the benefits they provide far outweigh the cost.
Movable Pulls: These are similar to their names, but work by allowing objects to move with the pull. Their movable parts are attached to the object to be lifted. They are also ideal for lifting heavy loads and can be found in utility elevators and construction cranes. They are also used in many other industries. They can also be made of wood, plastic or metal. The type of pulley you use depends on its intended use.

Mechanical Advantages of Pulley Systems

A pulley system is a simple machine that reduces the effort required to lift heavy loads. This mechanical advantage is proportional to the number of loops. For example, if you have a single rope loop, you must apply equal force to lift the weight. When you add another rope loop, you can lift heavier weights just by applying the same force. Therefore, a pulley system is an excellent way to use gravity to your advantage.
Mechanical advantage is a measure of the effectiveness of a pulley system. This ratio of force to work is called the mechanical advantage. In other words, if the rope system has a large mechanical advantage, it means that it requires less force to lift heavier loads. This advantage is usually measured in kilograms and is the same for all pulley systems. In general, the greater the mechanical advantage, the less effort is required to lift the load.
The mechanical advantage of a pulley system is that a single movable pulley requires half the force to lift an object than a single fixed pulley. Assuming frictionless bearings, the MA of a single pulley system is 2, similar to the MA of a single lever. A single pulley travels twice as much as it takes to move heavy objects manually.

Considerations when designing and installing a pulley system

The capacity of the pulley depends on the type and diameter of the cable. Besides its diameter, its sheath should also support it well. The basic function of the pulley is also important. However, most people tend to ignore the pulley selection process, resulting in ineffective load-pull capabilities. To avoid such problems, different parameters must be carefully considered during design and installation.
During the design and installation of the pulley system, the ratio of the cable diameter to the largest pulley diameter must be considered. Those who work in the industrial sector will have an idea of ​​this ratio. The greater the D:d ratio, the greater the capacity of the cable to withstand the load. The best way to ensure secure design is to take the right information and use it to design a system that is both robust and secure.
When designing a pulley system, it is important to remember that the pulley needs to have enough power to operate safely. In addition to horsepower, the belt should have sufficient elongation to absorb shock loads. If the elongation of the belt is very small, it is very likely that the teeth will be sheared or broken, causing serious damage to the system. Extensive belt sag should be compensated for by offsetting the driven pulley. Finally, the frame supporting the pulley should be rigid. Otherwise, the non-rigid frame will cause center distance and tooth skipping changes.

Add more pulleys to the system

Adding more pulleys to the spool might have some effect. The friction between the rope and the pulley increases with the number of pulleys, which in practice limits the number of spools. The best solution is to combine the pulleys into one housing. If the load is small enough, adding a few pulleys probably won’t make a difference.
Using multiple pulleys allows a single load to be lifted with half the force required. The longer the rope, the greater the mechanical advantage. In fact, a spool can withstand a load of 100 N. Additionally, adding more pulleys quadrupled the mechanical advantage. In this case, a single 100 N load would require a force of 25 Newtons.
When the rope is used, it stretches as the weight of the object increases. This will make the rope longer, increasing its length and increasing the distance over which the load can be lifted. Eventually, the rope will break and the lifted object will fall. Then you will have to buy a new rope. It may seem like an expensive proposition, but it pays off in the long run.

cast iron pulley

Cast iron pulleys are the most popular choice among industrial users. They are made of solid cast iron and usually cost very little. Their rims are held in place by a mesh that extends from a central boss. They also have spokes and arms that hold them in place. These pulleys are ideal for a variety of applications including fan belts, compressors and conveyors.
V-groove drive pulleys are ideal for general purpose pulleys. It has an inner diameter of one inch and is commonly used in feeders and ventilation curtain systems. Its steel straps prevent rust and ensure it meets or exceeds industry standards. 3-1/2″ cast iron pulleys are also available. In addition to the V-groove drive pulley, there are similar pulleys for power transmission. The V-groove drive pulley is powder coated for added durability.
The cross section of the arm is elliptical, with the long axis twice as long as the short axis. The radius of the arm is equal to the diameter of the pulley. The thickness of the arm is a key factor to consider when purchasing a pulley. If you’re not sure which material you need, you can always consider wooden or steel pulleys. They are lighter and have a higher coefficient of friction than metal pulleys.
pulley

timing pulley

Plastic timing pulleys have many advantages over steel timing pulleys. On the one hand, they are lightweight and corrosion resistant, making them ideal for applications that do not require high torque and tensile strength. Another benefit is their resistance to high temperatures. Plastic timing pulleys are ideal for applications involving flammable gases, solvents or particles. They can last for many years. For more information on the different types of plastic timing pulleys.
Vertical shaft drives require flanged timing pulleys. For large span drives, at least one of these pulleys must be flanged. The flange provides a secure connection to the shaft and prevents ratcheting of the timing belt. Finally, HTD timing belt teeth prevent timing belt ratcheting. These teeth need a large enough space to be seated. However, they can also cause a backlash. These pulleys are not suitable for applications where positional accuracy is critical.
Timing belt systems are designed to avoid such problems. The drive shaft and the driven shaft are aligned with each other. The pulleys are located on different planes and are connected by pitch lines. The pitch line of the timing pulley coincides with the pitch line of the belt. These pulleys are also easier to implement and maintain. It is better to use a synchronous system because the resulting gear system emits less noise than other systems.

Three basic types of pulleys, their applications and ideal mechanical advantages

There are three basic types of pulleys: movable, fixed and compound. Each has its advantages and disadvantages, and you should be able to judge which type is best for your needs by looking at the table below. Once you have mastered the different types of pulleys, you can choose the right pulley for your next project. Now that you have mastered the three basic types, it is time to understand their applications and ideal mechanical advantages.
pulley

describe

The stress characteristics of a pulley depend on its size and construction. These stresses are derived by comparing the stress characteristics of different pulley designs. Stress criteria include static and fatigue strength analyses and specify maximum stress ranges. Stresses are calculated in a 3D stress field, including radial, tangential and axial stresses. The stress characteristics of pulleys are critical to the design and manufacture of industrial machines.
The principal stresses on the pulley shell are distributed in the tangential and hoop directions, close to the centerline of the pulley. If the pulley has a wide face, the axial stress occurring near the shell/disk junction can be large. The stress distribution was determined using British Standard BS5400 Part 10: Stresses at the shell and end disc connections for infinite fatigue life.
Another type of composite is a pulley with a belt section. Such structures are well known in the art. The corresponding help chapters for these elements contain detailed descriptions of the internal structure of these components. Chamfers between pulleys can also be defined using multiple tapers, with a smaller taper extending from midpoint 44 to large diameter 42. Additionally, the pulley can have multiple taper angles, and as the pulley moves away, the taper angle is from the center.

type

A pulley system uses a rope to move the object and one side of the rope to lift the load. The load is attached to one end of the pulley, while the other end can move freely in space. The force applied to the free end of the rope pulls the load up or down. Because of this, the mechanical advantage of the movable pulley is two to one. The greater the force applied to the free end of the rope, the greater the amount of movement achieved.
There are three common types of pulleys. The cast-iron variety has a rim at the front and a hub at the back. The arms of the pulley can be straight or curved. When the arms contract and yield instead of breaking, they are in tension. The top of the pulley centers the belt in motion and is available in widths ranging from 9mm to 300mm.
The rope, hub and axle are mounted on the pulley. They are common and versatile mechanical devices that make it easier to move or lift objects. Some pulleys change the direction of the force. Others change the magnitude. All types of pulleys can be used for a variety of different applications. Here are some examples. If you’re not sure which type to choose, you can find more resources online.
pulley

application

The applications for pulleys are almost limitless. This simple machine turns complex tasks into simple ones. They consist of a rope or chain wrapped around a wheel or axle. Using ropes, one can lift heavy objects without the enormous physical exertion of traditional lifting equipment. Some pulleys are equipped with rollers, which greatly magnifies the lifting force.
When used properly, the pulley system can change the direction of the applied force. It provides a mechanical advantage and allows the operator to remain separate from heavy objects. They are also inexpensive, easy to assemble, and require little lubrication after installation. Also, once installed, the pulley system requires little maintenance. They can even be used effortlessly. Despite having many moving parts, pulley systems do not require lubrication, making them a cost-effective alternative to mechanical lifts.
Pulleys are used in many applications including adjustable clotheslines in different machines, kitchen drawers and motor pulleys. Commercial users of pulley systems include cranes. These machines use a pulley system to lift and place heavy objects. They are also used by high-rise building washing companies. They can easily move a building without compromising its structural integrity. As a result, many industries rely on technology to make elevators easier.

Ideal mechanical advantage

The ideal mechanical advantage of a pulley system is the result of rope tension. The load is pulled to the center of the pulley, but the force is evenly distributed over the cable. Two pulleys will provide the mechanical advantage of two pulleys. The total energy used will remain the same. If multiple pulleys are used, friction between pulleys and pulleys reduces the return of energy.
Lever-based machines are simple devices that can work. These include levers, wheels and axles, screws, wedges and ramps. Their ability to work depends on their efficiency and mechanical superiority. The ideal mechanical advantage assumes perfect efficiency, while the actual mechanical advantage takes friction into account. The distance traveled by the load and the force applied are also factors in determining the ideal mechanical advantage of the pulley.
A simple pulley system has an MA of two. The weight attached to one end of the rope is called FA. Force FE and load FL are connected to the other end of the rope. The distance that the lifter pulls the rope must be twice or half the force required to lift the weight. The same goes for side-by-side pulley systems.

Materials used in manufacturing

While aluminum and plastic are the most common materials for making pulleys, there are other materials to choose from for your timing pulleys. Despite their different physical properties, they all offer similar benefits. Aluminum is dense and corrosion-resistant, and plastic is lightweight and durable. Stainless steel is resistant to stains and rust, but is expensive to maintain. For this reason, aluminum is a popular choice for heavy duty pulleys.
Metal can also be used to make pulleys. Aluminum pulleys are lightweight and strong, while other materials are not as durable. CZPT produces aluminium pulleys, but can also produce other materials or special finishes. The list below is just representative of some common materials and finishes. Many different materials are used, so you should discuss the best options for your application with your engineer.
Metals such as steel and aluminum are commonly used to make pulleys. These materials are relatively light and have a low coefficient of friction. Steel pulleys are also more durable than aluminum pulleys. For heavier applications, steel and aluminum are preferred, but consider weight limitations when selecting materials. For example, metal pulleys can be used in electric motors to transmit belt motion.
pulley

cost

Replacing a tensioner in a car’s engine can cost anywhere from $90 to $300, depending on the make and model of the car. Cost can also be affected by the complexity of the pulley system and how many pulleys are required. Replacement costs may also increase depending on the severity of the damage. The cost of replacing pulleys also varies from car to car, as different manufacturers use different engines and drivetrains.
Induction motors have been an industrial workhorse for 130 years, but their cost is growing. As energy costs rise and the cost of ownership increases, these motors will only get more expensive. New technologies are now available to increase efficiency, reduce costs and improve safety standards.
The average job cost to replace an idler varies from $125 to $321, including labor. Parts and labor to replace a car pulley can range from $30 to $178. Labor and parts can cost an additional $10 to $40, depending on the make and model of the car. But the labor is worth the money because these pulleys are a critical part of a car’s engine.
