Replacing the bearing of air conditioner compressor Golf 4
Where is the bearing and how does it work?
The air conditioner compressor is in a hinged position on the engine (5). On the compressor there is an electromagnetic clutch with a bearing inside.
The part itself is located in the pulley (1), which the outer cage in a fixed position. Rotation is by rolling of the inside of the cage.

Photo Report Replacing the Air Conditioner Clutch Bearing
I recently purchased a car: Golf3, with an engine 1.8ABS, ’93. The clutch bearing of the air conditioner compressor was buzzing terribly on it. This was the subject of quite a bit of bargaining. Decided to replace. 1: Before you start, you must remove the minus terminal of the battery to avoid short circuits when you remove the alternator; 2: Remove the filter housing and remove the filter element;
3: Remove alternator belt by pulling up tensioner. Unscrew retaining bolts of the generator. There are two (in the photo and another below)
4: Unscrew the bracket. It is held in place with 2 hex 8 socket head bolts:
Unscrewed the 2 compressor mounting bolts with a 16 head:
we pull out a compressor on top, having disconnected a muff connector, but not disconnecting hoses of cooling agent; 5: we unscrew nut of a muff the wrench (either on 13, or on 14. I do not remember ). To hold the coupling I used a wrench from an angle grinder inserted pins in the holes around the axis (it was just right):
6: To remove the inner part of the coupling from the axle, you need to screw in 3 bolts long approx. 70mm into the holes around the axle. You need to screw in one half turn at a time. Under the removed part on the compressor will be the outer retaining ring:
remove it with a special puller (I pulled it out with round pliers). Next, use a pulley puller to remove the pulley itself from the axle. The sub-ring will be in it under the inner retaining ring:
Pull out the circlip, knock out the bearing with a suitable tool (I used a head on the. I do not remember ). Screw in the new bearing. I put the old bearing on it and bang on it. Install the retaining ring and enjoy looking at it :
By the way! Not having an original bearing and our stores refusing to deliver one, I pressed two more accessible 61907-ZZ bearings into the sheave. They have the same diameter, but the width is twice as narrow:
7: Here is the assembly process. It is carried out in the reverse order. When assembling all threaded joints I treated with a special compound against spontaneous unscrewing OmniFIT:
SD7V16 made in japan original bearing mark NTN: 2TS2DF0719LX2 After bearing replacement, the machine is unrecognizable! Engine whispering Good luck!
- One should check whether bearing noise depends on a condition of work of the compressor, whether the noise varies, if the conditioner is switched off. If so, you can very confidently consider the compressor bearing to be the cause of the noise
- You can also check the play in the pulley, turn it by hand, play should not be, if there is at least minimal play, the bearing should be replaced
- If the air conditioner compressor is located on the engine in an accessible place, you can hear exactly the source of noise
So, we have defined the source of noise. it is the bearing of the muff of the air conditioner compressor and it must be replaced.
For bearing replacement it is enough to remove only compressor muff, in this case there is no depressurization of the system and it is not necessary to recharge it. But, often, the compressor is located in a place where it is impossible to reach with a puller, in which case you have to remove the wheel, bumper or compressor itself, there is no matter what is more convenient to your mind or what is cheaper in terms of cost of repairs. After removing the compressor, we remove the clutch:

The Master Adviser
Good afternoon. Decided to share my experience since I did not find a network on this model. I have a VW Golf 4 1.8T AGU with non working air conditioner. Diagnosis with a tester revealed that the resistance of the electromagnetic clutch is 0 and when forced to power the clutch does not work. The situation is that the car is not yet needed and it stands. I’ve decided to try to reanimate the clutch and if not, then look for used ones at salvage yards. I will not describe how to remove the clutch, because many times described how to replace the bearing of the air conditioner compressor, and this is the same. I think that this type of repair will do everything, because inside the winding can not burn out because there all poured very well))
After removing the bearing, there is another retaining ring which holds the clutch, after removing the latter you need to unscrew the two tapping screws that hold the wire and now you have the clutch in your hands.
Gently knock down the protective layer, be sure to 45 degrees so as not to cut the wire if you hit at 90 degrees.
About opposite of the connector is a type of thermostat, a steel wire with a smaller cross section, that’s what burns out.
I decided to remove the entire shield, but you can not remove it, but only from the beginning to the end of the connection wire. After the ends were exposed, check the integrity of the winding inside by multimeter probing from the connector to the end of the winding. If both ends are ringing, all is well and all is intact inside. We need to wire both ends with copper wire, I only found the same cross section, I didn’t want to go somewhere in the store, that’s why I found at home.
After soldering, check the resistance, I had about 60 ohms, I had set the multimeter to 200 ohms and it showed 06.1. For greater certainty and understanding of the principle of this clutch connected to a power 12 and oh well it works))))
I didn’t pour it all back on, because it was filled with a lot of crap, I just used some new wire with a torque and that’s all. Thought it would be better cooled))))
The cause of overheating, in my version, were clogged air ducts, which are on the metal part of the.
All these channels were clogged with some kind of slag, I do not know what. Cleaned and washed everything. Reinstalled clutch engages and compressor cranks. Everything worked out. All thanks for your attention. I think someone will help))))

To identify the car and reliable selection of a compressor air conditioner Škoda Octavia 1U 1U2 Hatchback, you should carefully select the modification of the vehicle. For this purpose please use the data specifying: power in horsepower (example 103 hp), engine displacement (example 1,6 liter), engine type (petrol, etc.), engine displacement (example 1,5 lb.с.), engine displacement (example 1.6 liter), type (example gasoline) and model engine code, as a rule, this parameter is rarely used, but you can find it only in the certificate of registration, you can also pay attention to the axle drive (may be rear, front or full), well and the mandatory parameter release date, divides the model t / c on restyling, before restyling, first and last year of production.
This data serves to uniqueize the installed parts at a certain period of production, since the manufacturers are constantly upgrading cars from the assembly line.

Reworking the air conditioning compressor, some questions came up
What is that green oily stuff (clearly not Freon=) tell me more about it, it seems to be a leak detection toner (and a lubricant at that. ) Can I grease the thrust and needle bearings inside with heather or castrol lmh, or get some green stuff=) What happens if the pulley bearing jams. (you can guess, but you want to hear who had it happen.) I read that if I take the compressor apart, I have to change all the gaskets or there is no way to seal it Can I use gasket sealant.

Good day. Decided to share my experience since I didn’t find any on the net for this particular model. I have a golf 4 1.8T AGU with non working air conditioner. Diagnosis tester showed that the resistance of the electromagnetic clutch is 0 and when forcibly powered clutch does not work. The situation is that the car is not required so far and it stands. It was decided to try to resuscitate the clutch and if not, to look for used ones at salvage yards. I will not describe how to remove the clutch, as many times described how to replace the bearing of the air conditioner compressor, and this is the same. I think this type of repair will do everything, since the inside of the winding can not burn out because there is a very good primer))
After removing the bearing, there is another retaining ring which keeps the clutch, after removing the latter need to unscrew the two screws that hold the wire and here clutch in your hands.
Gently knock down a protective layer, be sure at 45 degrees that suddenly would not cut off a wire if you hit at 90 degrees.
Approximately opposite the connector will be a type of thermistor, a steel wire with a smaller cross section, and it burns out.
I decided to remove the entire protective layer, but you can not remove it, but only from the beginning to the end of the connection wire. After the ends are exposed, check the integrity of the winding inside by using a multimeter probe from the connector to the end of the winding. If both ends are ringing, then all gud and inside everything is intact. We need to save both ends with copper wire, I found only the same section, I did not want to go somewhere in the store, so I found at home.
After soldering check the resistance, I had about 6 ohms, put on a multimeter 200 ohms and it showed 06.1. For greater certainty and understanding of the principle of this clutch connected to a power 12 and oh well, the miracle of magnetism)))
did not pour everything back, because tat all poured from the soul, only a new wire filled with some momentum and all. Thought it would be better to cool))))
The cause of overheating, in my version, were clogged air ducts that are on the metal part.
All of these channels were clogged with some kind of slag, I did not understand what. Cleaned and washed everything. Reinstalled clutch engages and compressor cranks. It worked. Thank you all for your kind attention. I think someone can help))))
Photo report Repair of air conditioner, replacement of control unit of Golf 4 fans
Repair of air conditioner, replacement of control unit of fans
I decided to write a small report on the search of malfunction in the work of the air conditioner and replace related units and assemblies, maybe someone will find it useful.
One beautiful sunny day I turned on the air conditioner (it is air conditioning, not climate) and found that instead of cool air blowing like a blast furnace, which threw me into despondency and made me try to figure out what was wrong this time.
So, on the cabin side: when you turn on the button AC on a running car, it lights up, clicks, rpm drops as usual, but no cold. Underhood side: Fans don’t start, muff does not work, air conditioner piping is hot.
Check all the fuses, responsible for ventilation and air conditioning, both in the main unit and in a block over the battery (if a fuse died in a block over the battery, the button does not light up and the engine does not work, so once was the case) all normal.
Checking the operation of both fans when the engine overheated showed that one fan, the big one, would not turn. If you turn it by hand, the impeller rotates with a wild grinding, then after a trip to the electrician, testing revealed that the winding is also dead. Here is the original. part number 6X0959455A, replaced with Febi (2980 ). Changed is simple enough, unscrewing the 3 screws on the radiator and shifting the mount from the old to the new fan. If you will change, when you screw the screws back, constantly scroll the fan by hand so it does not catch the radiator and level the mounts to a full tightening, no grinding and snarls should not be. The fan replacement did not revive the unit, when the engine overheated both fans are running at both speeds, which is better than before
Found el. schematic https://vwts.ru/electro/g4/g4_cond_man_rus.jpg of the whole ventilation system and to the electrician. Check the pressure in the air conditioning system is normal, check the clutch is normal, check all the wires is normal.
We have artificially switched the clutch and here it is a miracle, the cold air blows, there is only one thing left to blame on the block of control of air conditioner fans, here is its orig. part number 1j0919506k (non-original Hans Pries 2380)
Actually change, this unit, which is located under the pad battery: Disconnect terminals accum, remove the fuse box, take apart a casing accum and unscrew one screw that holds the battery and take out the accum
unscrew the 4 bolts that fix the plastic pad under the battery and remove the pad itself
unscrew 2 bolts in the near left corner of the metal platform, which secure the block (photo from the fender)
we remove the block from under the metal platform, pull out 2 connectors and replace the block
We check the work of the condo and fans (we need a cigarette lighter to the battery) assemble everything in reverse order and enjoy the refreshing coolness in the cabin
