How to remove and reinstall a clutch on an a/c compressor



The AC compressor continued to turn even after I pulled the 12-volt supply wire to the unit. The AC compressor exhibited no unusual symptoms that would explain the locked clutch, there was no bearing failure, no unusual noise, On the contrary, the AC continued to work properly. The Jaguar cooled as good or better than the other cars I currently own, all of which have original factory 134a AC systems. uses the GM A6 compressor, a common compressor used by a variety of General Motor's cars I was not about to disassemble a perfectly working AC system because of a defective clutch. The project starts by removing the hood. Clearance in the Jaguar engine bay is non-existent. In addition, the AC compressor is located 3 inches from the radiator top support. it is possible to do this with the hood on you will regret it. The objective is to replace the AC clutch on the car. Remove the AC compressor's front and rear bolts only. Lift the front of the compressor up to clear the top radiator support. Do not depressurize the system or remove any hoses.
Remove the center 9/16-inch nut from the compressor shaft. A special clutch holding tool is not needed if an air impact wrench is used.
install the clutch removal tool. The clutch is "press fit" to the AC compressor front shaft.
Instead of a clutch holding tool, I used a bar resting on the engine (blue arrow) to hold the tool removal nut while I turned the center stud that forces the clutch off.
The pulley is now completely visible. You will need a large snap ring pliers to remove the snap ring that secures the pulley.
Notice the towel below the compressor. Snap rings (red arrow) have a habit of flying off the pliers and disappearing forever into the engine. You are farned
The pulley is a zero clearance fit to the compressor nose. If you are lucky it will slide off by pulling on it. You will probably not be lucky. I used a puller to remove the pulley. Be careful here. You must identify what the puller can and cannot push against. The center compressor shaft must not be used as leverage to pull or push any component not on the compressor shaft. A 1 1/8-inch, 1/2-in drive socket (red arrow) will fit over the center shaft and rests on the compressor nose cone. This is my leverage point. I taped a large washer (blue arrow) to the socket to provide a contact point for the puller.
Attach puller jaws in the pulley groves and place the modified washer to rest against the nose cone. Slowly tighten the puller to remove pulley.
Locate and secure pulley key. If the key stays on the compressor shaft, do not remove it. An even bigger snap ring secures the coil assembly to the compressor. Remove the snap ring.
Remove coil assembly.
The clutch release springs (blue arrows) also appear to be in working order.
Testing the resistance of the coil assemblies indicate that they are within specs. The old coil pack reads 4.8 ohms.
The rebuilt coil pack reads 4.5 ohms.
In removing the clutch it appeared the coil was permanently energized. The clutch removal tool had to forcefully pull the clutch from the pulley. I was not about to put this coil pack back on. I cleaned the contacts on the rebuilt unit prior to installation.
Gently clean the nose cone remove any surface rust. the clutch bearing rides on this surface, it must not be damaged.
connect coil pack to compressor and install. Make sure the coil pack is attached properly to the electrical connector. There are three indicators on the rear of the coil pack that must match the corresponding holes in the compressor body (red arrow). Install big snap ring.
Clean pulley surface and install pulley. The bearing might require some slight persuasion to slide onto the nose cone. Use a drift (red arrow) that contacts the inner ring of the bearing only. Tap gently until the pulley bearing seats.
Install second snap ring. Make sure that the snap ring seats fully in the shaft grove. Tap the snap ring fully into the groove with a screwdriver if necessary. (red arrow)
Clean clutch mating surface and install clutch to the compressor. Note position of shaft key and corresponding clutch key slot. (red arrows). Make sure they line up before installing clutch to compressor shaft.
use the clutch installation tool. The front of the tool (blue arrow) screws over the threads of the exposed 9/16-inch shaft stud (yellow arrow). The nut then forces the bearing (red arrow)against the clutch face, forcing it onto the compressor shaft. One side of the bearing rotates with the nut to reduce friction as it forces the clutch onto the shaft. Note that the forces all act on the compressor shaft, not against it.
Hold the center bolt while tightening the nut down.
You are looking for a pulley clearance of .010 to .015. If you inadvertently create too close a gap, put the clutch puller back on and pull the clutch out accordingly. Replacement and or rebuilt parts are rarely perfect. You will probably get different readings at various locations around the circumference of the clutch. If the closest gap is .010 or more and the largest gap is .015 or less you are OK.
Install 9/16-inch self-locking nut and tighten. If a clutch holding tool is not available, then finish tightening this nut after the compressor belt is on and the clutch energized. This nut does not hold on or impacts the position of the clutch. It appears to be a safety precaution just in case the press fit clutch somehow comes off the compressor shaft.
Install compressor to engine. Tighten 4 bolts to engine bracket. Connect electrical connections to coil assembly. Install belts.
Turn on your vehicle and let there be cold air, good luck sorry illustrations wouldn't load to this format

How to remove the a/c clutch from a 1998 gmc sierra 1500 5.7 l


I believe this AC compressor is the same as my '95 Astro. The clutch is pressed on to the compressor shaft. You should see a threaded hole in the center of the clutch and a threaded screw in the center of that hole. To get this off you have to have the proper puller. It threads into the clutch and has a screw that you tighten against the end of the screw in the clutch. This pulls the clutch off the compressor (maybe, if it isn't frozen to the shaft). FYI, I just replaced my AC compressor and found that a new compressor with a new clutch was only about $40 more than the clutch alone. The puller cost $30.) Of course, if you replace the compressor you have the work of some parts in the AC system and recharging it. There are some good web sites with good pictures and instructions you may want to look into before you decide. I found that when I replaced the compressor, I had to replace the accumulator and compressor oil and there is some question about flushing the AC system when you install a new compressor. Hope all this helpful. Good luck.

Ac compressor clutch is making a noise is the clutch is replaceable without replacing compressor


I had the same issue with my 2006. I thought the compressor clutch bearings were faulty. After further research, the rattling noise was actually coming from the serpentine belt tensioner. Easy repair!
Hope this helps.

Ac compressor not switching on 1986 Peugeot 505.GTI How can I test clutch wiring,. Have just aquired this car , heater blowers etc. working but ac clutch not cutting in, is there a switch I have not found....


The best thing to do first is to check the AC clutch itself if it's working, locate the air - con compressor and you will see a wire coming out from the front top of the AC-compressor, it has a connection, remove tht connection and take a piece of wire, connect it to the wire frm the AC-compressor and the other end of the wire to the battery positive terminal,by doing so you will hear a clicking sound of the clutch at the AC-compressor, better still is to start the car's engine, switch 'ON' the AC as normal, let the blower blow thn connect tht wire frm the AC-compressor to the positive side of the battery terminal and check it out if the AC-compressor rotates and also you may get in the car and see if its blowing cold air.
Please also check this -->
HEAT/COLD selector (on the dash) is not selected at HEAT...if it is thn the AC-compresor clutch will not kick in!
Hope this helps!

Rebuild AC Compressor RSX 2004


You can replace the clutch assembly without removing the air condtioning compressor you need to buy the tools to remove the clutch with. Need more information if you are going to tear into this as it can be expensive and I would not open up the system unless you had too.
