It takes a special puller. Your local auto parts store should have one available.
The bearing lets the belt pully free wheel on the compressor input shaft that the clutch is attached to.
You need a Z7 Clutch puller.
Remove freon via EPA mandated instructions Remove drive belt from engine pully Remove AC hoses from rear connections of compressor Remove compressor mounting bolts
The only way you can do this that I am aware of, is to by an after market pully for the vehicle, you have to unplug and remove the A?C compressor, and bolt the new pully/bracket to the engine blok in place of the compressor.
sometimes there is a nut right in the center of the pully youcan loosen but sometimes it is pressure fitted on and you need a special machine to get it off.
If you are wanting to stop the A/C from working, then just pull the fuse or disconnect the power to the compressor clutch. take the slack by using a half inch rachet on the tension pully,remove the part of the belt from the a/c compressor use a peice of string or tape and mark the slack auto will give you a belt that will be close to what u need . It worked for me
You realy can't. If your intention is not to power the A/C unplug the wire that connects to the electric clutch. It should be right behind the pully.
Check the following........ 1. Clutch coil wire harness for proper connection. 2. Power and ground to the clutch coil wire harness. 3. Pressure switches.....
It depends on the type of problem you have with the compressor. If you aren't getting cold air from your A/C system and you are sure that all the other components such as the condenser, evaporator, radiator and refrigerant are good, the compressor is faulty and needs to be changed out, the pully can still be free turning yet the compresser not functioning. If the pully does not move, the compressor is seized and needs the be changed out completely unless you want to waste your time rebuilding it, and usually it will cost you more in parts IF you can even find them to buy. If the pully is free turning and the compressor not engaging, the clutch is bad and can be changed, but usually isn't worth the time and the cost savings are minimal if at all. If the compressor functions as it should but the pully is damaged and is tearing belts and things like that, yes the pully can be changed, very easily, be sure to get the same diameter pully as this pully size has direct relation to the clutch in the compressor. Basically, when you're talking about an A/C compressor, its always more economical and just plain easier to change out the entire unit than to monkey with the present one unless of course, you like headaches;) my pulley was frozen due to bad bearings causing the car to crank to slow to start. drove me nuts trying to figure out why it wouldst start and why it was not cranking fast enough to start. much easier to replace the pulley rather then the compressor and way cheaper. trust me on this i have a 1994 3.4 camaro that is the hardest car i ever had to work on i hate this car!!
The compressor is simple to remove assuming there is no more freon left in your system If this is not the fact, you will need to have the freon vacummed out, and this can only be done at a repair shop. As far as I know it is against the law to bleed Freon out into the air. to remove the compressor, first you need to remove tension on the serpentine belt by turning the belt tensioner. once the belt is off, you can unplug the electrical sensor. the compressor is held into the bracket by a number of bolts. on the pully side all the bolts are 13mm. there are 3 of them. on the back of the compressor there are 3 more bolts, these bolts being 10mm in size. remove the A/C lines and pull the compressor out of its bracket.
First thing to do is check that the compressor clutch is engaging, when it is not working properly. If the outer pully is turning, as it does whenever the engine is running, and the inner part of the clutch is not turning, that could be your problem bad clutch or electrical connection . The inner and outer parts of the clutch need to be turning for the compressor to function. Have someone turn the AC on and off while you watch the clutch.
I changed the drive belt and idler pully,now only one back wheel works.how do I fix it
