This requires an expensive set of special tools designed to remove and replace the clutch. It can be a complicated task.

The compressor is going out. The only time the compressor actually runs is when the clutch is engaged, the rest of the time the pulley acts as an idler pulley and just free wheels. I would suggest replacing the compressor and the accumulator.

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

Ac pulley wobble repair or replace


I doubt it can be repaired without replacing the clutch. It would depend on what the cause is. If the bearing is failing the clutch would have to be replaced.

AC Clutch noise and vibration


An A/C clutch will not make this concern happen, more likely the A/C compressor is begining to go out. The belt on the A/C clutch Assy. free wheels (spins feree on the pulley) when clutch is not engaged. If concern is not present with A/C off this means the bearings in the puley assy. ok. Once the A/C clutch is engaged it locks the compressor against the spinning pulley and turn the compressor chaft and spins the A/C compressor internal shaft. If you hear a loud "screach" when you turn on the A/C it means the belt slipped for a second, if it continiues to screach it means either the belt is loose or that the compressor is internaly locking up. I wouild start by checking the belt tension (if not equipted with and auto tensioner). You can also remove the belt and turn on the A/C and attempt to turn the clutch/pulley by hand, it should turn with a little effect but should not bind or lock at times if that happens compressor is bad.

I ust had the water pump replaced. Now my ac has gone out. I know nothing about cars but I do know that I hear a strange noise and the front part of the ac unit was turning and now it's not. It seems...


It is unlikely that the replacement of the water pump and AC failing are related, however ensure that the V belt is correctly positioned and under tension. The AC pulley should be spinning continuously by the V belt. The AC compressor is engaged by an electrically operated clutch within/behind the pulley wheel. If the pulley wheel is not spinning but the belt is sliding over it then you have a seized AC compressor and this will most probably need replacing. If the wheel is spinning but the AC compressor is not working (no cooling) then it is the clutch that is not engaging. This could be due to a worn clutch, failed clutch actuator, broken electrical connection, failed relay, broken fuse a failed interior thermostat (the car thinks that the 'set' temperature has been reached and so switches the AC off). To check, put the AC on the lowest setting and test the voltage at the AC compressor connection. If voltage is being supplied it is likely to be a failed AC clutch. There are lots of AC clutch repair videos on youtube and these should be a great help.

My jag's a/c compresor froz up and now shop wast 1200.00 for change out and charge system. Is that all it will need jag X type 3.0


The AC is driven by a pulley pulled by the serpentine belt. When the AC is switched on an electrical clutch engages the driven pulley with the AC compressor on the same shaft. If the AC compressor is frozen up the pulley will not turn when the AC is switched on and the belt will squeal as it is pulled over the static pulley wheel. If, when the AC is switched on, the pulley wheel continues to spin then it is likely that the electrical clutch is not engaging. It is much more often the case that the clutch fails before the AC seizes. If this is the case check out the AC fuse and clutch relay. The fuse can be inspected visually and the relay can possibly be inter- changed with one that is similar (windscreen wiper or electric windows). The relay should make a 'click' that can be heard when the AC is switched on. Put the suspect relay into a circuit that you know is working in order to check it.

When I open the hood of my 2000 tdi beetle, and look at the upper front strut mounts, the cone around the strut bolt is loose on both sides. I had both struts replaced 2yrs ago. I just had my tires...


the cone naturally has some clearance between the body. on the underside of what you see is a rubber bushing called the 'upper strut mount' these are a commonly replaced item. you need a spring compresser to get em out.

How do I take the AC compressor clutch off


Depending on the type of vehicle you will need the specific thread size clutch pulling tool. Any MAC or Snap-on, and most common auto parts, NAPA AutoZone Ect... will carry the proper tool.
