Its primary function is to provide tension and guide the engine drive belt. These belts wrap around the various parts of the engine such as the power steering pump, alternator, water pump etc... To keep it simple, idlers are complementary pulleys that make the entire system run smoothly.

How does a pulley motor work?
A pulley is a wheel driven by a motor. A belt is looped around this wheel and around a second wheel. When the motor is turned on, the powered wheel turns the belt which turns the second wheel. This arrangement can be used to either increase power, increase speed and to change direction of motion.
What are pulleys used for?
A pulley is a wheel that carries a flexible rope, cord, cable, chain, or belt on its rim. Pulleys are used singly or in combination to transmit energy and motion.
How does a pulley increase fan speed?
Adjusting the Blower Speed
To increase blower speed, slightly loosen the setscrew that holds the pulley to the driveshaft. Move or turn the pulley clockwise on the shaft one turn, then tighten setscrew. If more speed is desired, turn the pulley clockwise two turns.
How long can you drive with a bad pulley?
So, how long can you drive with a bad idler pulley? The safety recommendation is not to drive the car at all and take it to a mechanic immediately. You should be concerned if the vehicle makes squeaking or rattling noises. The car can still run for months or break after a few days.
How much does it cost to replace a pulley?
The cost to replace the idler pulley of your driver belt will usually be somewhere between $80 and $200. The cost for the new part should only be anywhere from $40 to $90, while the cost of the labor will be anywhere from $40 to $110.
What noise does a bad pulley make?
Squealing. When the engine is idling, a bad pulley may make a squealing sound. This is due to the bearings in the pulley going bad. The bearings may also make various other sounds such as clattering or even a rumbling sound, making the vehicle sound as if there was much more wrong than a bad pulley.
What is the main advantage of a pulley?
The main advantage in the use of pulleys is that the effort becomes less as compared to the normal lifting of the weights. In other words, it reduces the amount of actual force required to lift heavy objects. It also changes the direction of the force applied.
What is pulley in mechanical engineering?
In engineering, a pulley is a wheel which has a grooved rim for carrying a line. The pulley turns in a frame or block, with the purpose of either changing the direction of force or transmitting force. The simplest use of a pulley is when one end of the line is pulled to raise a weight at the other end.
What is a pulley car?
A motor pulley is a type of wheel that is affixed to the engine of an automobile or other vehicle; this wheel is used to guide a timing belt or serpentine belt that helps power peripheral devices in the car such as the air conditioner unit.
How do pulleys reduce rpm?
Add half of the diameter of each pulley to twice the shaft-center-to-shaft-center distance. Get the next larger standard size of belt. Install the belt on the pulleys and move the units apart until the belt has a slack of about 1/2 inch.
How do pulleys reduce motor speed?
By changing the diameter of the pulley wheels, speed can be changed. A smaller pulley turning a larger pulley results in the larger one moving more slowly but with more shaft power.
Does pulley size make difference?
A larger diameter pulley wheel (aka sheave) is technically more efficient than a smaller diameter pulley. But it's a trade off: a larger pulley has increased bulk, weight and cost. For example, in a 1:1 haul, you gain about 7% efficiency going from a 1.5” pulley to a 3.75” pulley.
How many pulleys does a car have?
There are two main types of car pulleys: crank pulleys, and accessory pulleys. Most pulleys are driven by a main crank pulley, which is bolted onto the crankshaft. When the engine is operating, the crank pulley rotates, transferring motion to the other pulleys by means of the serpentine belt or v belt.
Can a bad idler pulley cause alternator problems?
Alternators are DRIVEN by the serpentine belt. All that happens when the belt disappears or pulleys seize is the alternator stops turning; there is NO possibility of damage to the alternator.
