Usually, the answer is yes. the crankshaft pulley drives belts which in turn drive auxiliary devices such as alternators, generators, water pumps, smog pumps, Power Steering pumps, A/C compressors, etc.
There are a few occasional exceptions where some auxiliaries are driven by gears connected to gears within the engine. Some of these instances include the engines in heavy construction equipment, agricultural tractors, and large truck tractors.
To drive the belts
Power steering belt to crankshaft pulley. Alternator belt to water pump pulley and to crankshaft. A/C compressor belt to power steering pump and to crankshaft pulley. Smog/Air pump belt to water pump pulley. This is for a truck that had a 2 grove power steering pulley, a 2 grove water pump pulley and a 3 grove crankshaft pulley................
I would check front crankshaft seal or timing cover gasket. The Crank pulley might be "throwing" oil on to the belts and Alternator.
bottom of engine where belts go
Alternators are driven by belts attached to one or more pulleys on the engine to turn the pulley on the alternator.
Hello! The crankshaft position sensor is located behind the crankshaft pulley,on the left side facing the front of the car.It is difficult to see and to remove it you need to remove the crankshaft pulley ( radiator,belts,.... )
The most logical reason for the key or tip as you call it breaking off is probably a result of improper torque on the crankshaft pulley or the crankshaft pulley is out of balance.To prevent this I would highly suggest buying a new crankshaft pulley that will be balanced.To explain what happens over time the strain of adjusting the belts from the alternator and power steering and air condition pull the crankshaft pulley with varied tension and can cause the crank pulley to warp to a degree causing it to be unbalanced.While this may seem a bit strange the metal will be affected by this due to age,temperature,torque from the belts tensions pulley left and right.Best bet buy a new crankshaft pulley (note just look at the pulley while idling and see if is wobbling) this will tell you the pulley is warped or out of balance.Plain and simple!
First of all, they are the same as the fan belts on any other car. The fan belt(s) are the serpentine drive belt(s) that turn your fan and other accessories (like alternator, compressor, power steering) They are often referred to as serpentine belts, drive belts, and accessory drive belts. The are located on the outside of your engine, driven by the main pulley (crankshaft pulley). R. Mesyef
I'm assuming you mean a pulley, which is what the belts run on. If so, depending on which pulley the bearings could be bad or if it is the crankshaft pulley (big pulley near the bottom) the rubber could be getting bad.
It transfers power from the alternator to the crankshaft and the camshaft to make your engine work.
1. Buy new alternator and go to where your car is. I also recommend buying two new alternator belts - neither is a spare, Saab put two on it. 2. Unhook the battery. If the new alternator doesn't have a pulley, use the belts to keep the alternator pulley from turning and break the pulley bolt free. 3. Loosen the two bolts holding the alternator in and push it toward the engine until the belts can be removed. Remember how they went on. 4. Unhook the two wires from it. 5. Remove the two bolts, then lift out the alternator. Careful, they're heavy. 6. If there's no pulley on the new alternator, move it from old to new. 7. Set the alternator in place. Put the bolts in but leave them loose. 8. Put the belts on. If you moved the pulley, tighten its bolt good and tight now. 9. Adjust the belt tension, then tighten the alternator bolts. 10. Reconnect the wires. 11. Hook up the battery.
On the alternator belts, there is a pivot bolt that needs to be loosened located on the top of the alternator. There are also a lock bolt and a belt tension ajustment bolt located on the driver side of the alternator. As you loosen the ajustment bolt, the belts will come right off. The A/C belt uses an idler pulley accessed from under the car. That lock nut is in the center of the pulley, and the ajustment bolt is located on the side of the pulley. There is no pivot bolt for this belt.
