Please be more specific with your question. Did you attempt to change this alternator yourself ? Was there a reason to change this alternator. Did your new alternator come with a pulley installed on it.. Please be specific about the events leading up to this question. Most times there is no "allignment necessary when removeing and installing an altenator. You take one out and put the new one back in the same way. If you mean you don't know how hte belt is run from pulley to pulley please look under the hood for the MFG sticker detailingf this. hope this helps Phil
You remove no pulleys. Just loosen the belt and then remove the alternator.
Alternators are driven by belts attached to one or more pulleys on the engine to turn the pulley on the alternator.
In automotive terms, There are drive pulleys such as the drive pulley mounted to the crankshaft on most engines. There are driven pulleys such as an alternator, power steering, water pump, a/c compressor and all the accessories driven by the drive pulley. There are idler pulleys and tensioner pulleys. There are timing belt pulleys. And for non automotive related terms, There are block and tackle pulley systems. There are pulley hoists. Wire rope pulley blocks. Cable pulleys. Rope pulleys.
An alternator pulley transfers mechanical power from an engine crankshaft to the alternator shaft via a belt. It's interesting to note that on some engines, there are no pulleys and the power is transfered via solid gears.
You will first need to loosen the serpentine belt in order to remove it from the drive pulley. After that, it is bolted to the engine in 2 locations, which should be rather obvious, then remove electrical connections.
you have to push down on the tension pulley, then you would get slack in the belt
Removal of Alternator PulleysOver the years I have ruined several an Alternator pulleys because I refused to spend the money to buy an Alternator Pulley Removal Tool.I finally learned the hard way, and for a long time have used the proper removal tool; no more ruined pulleys!!!!Due to the design of Alternator Pulleys, an ordinary "Gear Puller" cannot get a "proper grip" on the pulley flange, and the force necessary to overcome the friction of the force-fit of the pulley to the shaft results in damage to the pulley.Go to any auto parts supply store and buy an Alternator Pulley Removal Tool. They don't cost much, and are well worth it in time saved, and the cost of replacement pulleys. Then just follow the instructins that come with the tool and you should have not trouble. Good luck!

The plural of pulley is pulleys.
The pulley on the lower passenger side is the air conditioner pulley. The one on the lower drivers side is the power steering pump pulley. The one above that is the alternator pulley. The pulleys on the low center of the motor are the crankshaft pulleys and the one above it is the water pump / fan clutch pulley.
Chrysler has a belt and pulley kit to fix the problem. it removes the smooth surfaced pulleys and replaces them with grooved pulleys. the new belt is grooved on both sides
Two kinds of pulleys are the fixed pulley and the movable pulley
