Because the bearing in it has worn out and it is locking up causing the belt to break.

What is the correct routing for a serpentine belt on a 1999 BMW 740 il car?
It is important to have the belts of a car put in the right direction. This serpentine belt goes around the AC compressor, above the AC tensioner,under the crank pulley, around the power steering, over the alternator pulley, under the idle pulley, around the w/p,and behind the tensioner.ÊÊ

How to replace the lower accessory belt not the serpentine belt on a 2000 2500 6 liter silverado?
To replace the AC belt which is separate from the serpentine belt on a Chevy 2500 V8 6 liter do the following: Turn the AC switch on the dash to the off setting. Remove the bottom cover under the engine. Remove the air intake pipe from the filter box to the top front of the engine intake. Loosen the serpentine belt by putting a wrench on the idle pulley bolt on the front top of the passenger side of the engine and pushing downward to take pressure off the belt. While doing this, you can slip the serpentine belt from under the idle pulley thereby creating the slack needed to remove the belt from the main engine crankshaft pulley. Carefully let the idle pulley back up into position as it's spring is very strong. You can get hurt if not careful. Now from under the front of the engine, slip the serpentine belt off the engine crankshaft pulley. Before installing a new belt, be sure your AC compressor has not frozen up by turning the clutch by hand. If it has, it will just break a new belt instantly upon starting the engine. Put the new belt over the AC compressor pulley. Using a 3/8 driver, move the AC idle pulley enough to get the belt over the crankshaft pulley and under the idle pulley. Now, put the serpentine belt in place as much as possible from the underside. Go back to the wrench on the idle pulley on top of the engine, apply enough pressure to allow putting the serpentine belt in place. Replace the air intake pipe. Make sure all tools are out of the engine area. Start the engine and turn on the AC. If everything is ok, turn off the engine and replace the bottom pan.
Chattering sound at the front of the engine when running and when put in gear with the foot on the brake and givivg it a little gas it becomes a squeeking sound If you put it in neutral and re?
I suspect a bad harmonic balancer. Sloppy and making noise at idle belts squealing while under load. If vehicle has an serpentine belt system could be the idler pulley.
99 jeep Cherokee serpentine belt squeal and voltage drop when running with the heat or lights on The serpentine belt battery and idle pulley has been replaced within the last 2 months?
Possible problem with the alternator. Could be source of the noise if it's bearing is going out.
You tightened your serpentine belt on your 1989 4.0 Cherokee now it wont idle Is there a idle vacuum line on the power steering?
There is no idle vacuum line on P/S. I don't know how you tightened a serpentine belt when their is no provision for doing that. The tension is controlled by the idler tension pulley. If you are referring to a normal drive belt, then set the deflection at mid point of the belt to approximately 1/4". Check with Chrysler for the exact specs on deflection.
What is a idle pulley?
idle pulley is a pulley on an engine that does not drive any accesories ,such as water pump or alternator. it is put there to route the belt so as the belt will not hit or rub on other parts or accesories
Is there a tension or Idle pulley in the Timing Belt system If so Can it sqeal or sound like bearings are wearing out?
absolutely. If that is what is squealing and it ceases the timing belt could be damaged and in some engines cause major damage. Non clearence engines can smash vales and pistons and even crack heads and pistons. Go to http://www.gates.com/part_locator/index.cfm?location_id=3598&go=Interference to find out more about timing belts. There is also a tension pulley on many serpentine drive belt assembly. This belt is usually very long and goes the engine pulley, alternator, PS pump, AC pump. The idle pulley applies pressure to the back side of the belt, the flat and opposite side that would fit into the slots of accessory being driven.
How do you rout the auger belt on a montgomery wards snow blower?
Take all the belts off it first. The auger and drive are powered by the motor. The belt that powers the drive wheels will be closes to the motor and the belt that drives the auger will be closes to the auger. The space to attach the new belts will be on the motor side of the bottom pulley closes to the motor. Put the auger belt on the bottom pulley that's closes to the auger first but don't attach it to the top pulley. Next, put the drive belt on the bottom pulley closes to the motor- this belt can be attached to the top pulley closes to the motor. Now, the auger belt can be attached to the top pulley closes to the auger. Both belts have idler pulleys that keep them tight. These pulleys run on the outside of the belt. I use a bar when removing and replacing the belts inside of my fingers to guide the belts off the top pulleys. I make sure that the idle pulleys are the first and last that the belt gets attached to or removed from. These idle pulleys don't have to be removed for the replacement of the belts. I pull the starter rope slowly to help install the new belts. Remove the spark plug first. Accidental start ups can happen. The pulley/belt system can cause severe damage to your fingers- so don't use your fingers when guiding the belt on and off the top pulleys. Replace the belt guard if your snow blower still has one.
