Eg volkswagon has a timing belt and a pulley tensioner that make the car run if they go your car won't work. They are supposed to be replaces every 100000km and when you replace one you replace both of them along with the watercpump because the labour is expensive and you don't want to have to pay to do it again in a month
no belts aren't a type of pulley
To drive the belts
They snap to the max.
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.
Put the new fan belts around the fan pulleys. Slide the top tensioner pulley upward. Tighten down the tensioner pulley when you have achieved the proper fan belt tension.
Large drive pulley, small driven pulley = faster rotation but less torque. Small drive pulley, large driven pulley = slower rotation but more torque.
bottom of engine where belts go
remove all belts,tensioners etc, remove pulley bolt, use HARMONIC BALENCER PULLEY to remove - DO NOT USE NORMAL PULLEY REMOVER - must be pulled from center of pulley not from outer edge
Lift car on jack stands, remove right wheel for better access,remove any belts, remove pulley bolt, then use a pulley remover to remove pulley, carefully pry out old seal thebn tap in new seal with mallet or plastic hammer, if pulley has ridges on it you may have to replace pulley or you might still have leaks. reinstall pulley,bolt, belts and wheel. Good Luck.
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
If you have a Mercruiser, there was a recall on the pulley that was first used. As I remember, the pulley was wearing out the belt prematurely causing it to break, and or jump off. I would check with a Mercruiser dealer to see if applicable to your engine.
There are two basic types of pulleys. When the grooved wheel is attached to a surface it forms a fixed pulley. The main benefit of a fixed pulley is that it changes the direction of the required force. Another type of pulley, called a movable pulley, consists of a rope attached to some surface. The wheel directly supports the load, and the effort comes from the same direction as the rope attachment.
