Almost all modern cars are equipped with climate control or even air conditioning. And it concerns even such budget brands as ‘car” and “author”. Often car owners do not know how to service the air conditioning and go “while it is working”. However this system requires proper attention. Otherwise you will need expensive repairs. Not to bring a car to this state, he needs replacing consumables. Today we'll look at how to replacing the bearing of the AC compressor (“Chery Amulet” as well).
This element represents a part of a car air conditioner. It differs in its design the presence of seals and thin walls. In addition, this element is of two types – angular contact and double row. Both types are designed to work at high speeds. This type of design is ideal for automotive air conditioners, and with built-in seals are well protected from the negative impact of external factors (salt, water and dirt).
Why the need to replace the clutch bearing a / C compressor, if it is well protected from the external environment and is designed for high speed? This element wears out due to exposure to grease, which over time dries and thickens. Because of this, the bearing balls are starting to warm up and break the separator, causing the mechanism to simply go crazy. If the car is over 10 years, is an occasion to reflect about the need for bearing replacement a / C compressor. «there», equipped with such a system could require repairs much sooner, if not observed a stretch of the belt. If he win, the item will fail.
How to determine that the car needs a bearing replacement a / C compressor? “wheels” SE and other cars, in the configuration which is air conditioned, diagnosed without special tools. A characteristic sign of wear of any bearing – it's the sound of the roar. In our case, it's a loud rustle – the friction of metal parts. Is this bearing in the clutch area (in right of engine, below). First you will hear a light rustling (sometimes intermittent), you may not notice. But with time the situation will intensify. The bearing is humming stronger and stronger.

Replace the pulley bearing air conditioning compressor must be done at an early stage fault detection. During long-term operation worn detail can form the skew. Thus it will affect the electromagnetic clutch system. As a result, you will require not only replacement of the bearing of the compressor of the air conditioner. “the Nissan is a Premier", equipped with this system may require additional Bay for the new freon.
First we need to remove the compressor. This is done on poddomkratit car. It is better if the machine will stand on a pit or overpass. If not there, rip off the bolts, domkrat vehicle front side mounting of the compressor and disassemble the wheel. Also, avoid falling off the car, should be put under the spar spare wheel. Next, Unscrew the mounting bolts compressor – four of them. If it blocks the generator, it too must be removed (after turning off both battery terminals). Then Unscrew the bolt clamping the clutch plate and take it out. On some vehicles will require the removal of freon.
To do this, you need to Unscrew the clamp for the rubber pipe of the compressor. They unscrewed very smoothly. Remember that the freon comes out under pressure.
So, after the successful removal of the pulley you should remove the bearing. The latter is attached a retaining ring. If he flared, the dismantling, we will need a hammer and chisel. Next, you remove the old bearing. For this use a special puller. If not, you can use the old clip from the bearing. Remember that when removing the item may be damaged if much pressure on the outer part of the pulley. After removing the old parts is bearing replacement a / C compressor. “author” and his clutch have a greater sensitivity to mechanical shock, so the pressing element is done by means of a screw or hydraulic press. Further, when the detail went to its place, set back retaining element and produce the Assembly in reverse order.
If you replace the clutch bearing AC compressor, special attention must be paid to the torque and sequence of tightening all mounting bolts. Otherwise, the element can crack. As for the freon, which we removed, the subsequent filling is carried out only by that type of part number on the compressor. When removing the latter is necessary to ensure the tightness of the output and input holes. The slightest moisture can cause breakage,and that would require not only replacement of the bearing of the compressor of the air conditioner and repair the entire system. It is important to achieve maximum tightness not only of the removed element, but approaching it pipelines. The presence of moisture quickly disables the compressor. Also, before you refill freon experts recommend evacuation system.
Just note that to use this method you need in a pinch. If it is possible to use a press (from a neighbor's garage, for example), do not be lazy and turn to him for help. So, we will need to fix the compressor clutch. You can use the native socket wrench (which we spun the wheel) or puller for disc grinders. Unscrewing the nut, the hook with a minus screwdriver disk. Next, remove the snap ring. After that, we need a puller. They will serve as head by 30 millimeters. Turn the clutch and looking for the bearing with the notch on the edges (this is to ensure that the mechanism has not taken off from the seats). Then with a hammer gently tapped on the head – the detail will begin to go out.
Not to bend the clutch at the time when you replace the bearing of the AC compressor, it is recommended to enclose under it a flat piece of wood or thick cardboard. Next, clean using piece of cloth seat. If there is rust, clean it thoroughly. To do this, use a rust Converter (along with ‘wadeskog”, really need in the garage thing). If not, you can use fine-grained sandpaper. Next, grease the seat and start pressing the new bearing. For this we need the old element – apply it to a new and easy blows of a hammer produce the press fit. Not to damage the element, it is recommended that produce beats in a circle. Next, make notches and collect the item in reverse sequence. This bearing replacement air conditioning compressor with their hands successfully completed. After Assembly it is important to control the noise of the element. New part should run silently. The slightest noise and the rustle of talking about the wrongness of compliance technology replacement. Or is it a factory defect.
If the element is “disposable”, some motorists prefer to repair. After removing the pulley you should remove the part of plastic protective cover. Next, we need any solvent (this can be rubbing alcohol, gasoline, antisilicone or mineral spirits) and brush. Her wetted part and remove the old, dried grease. Next, take any high temperature grease intended for bearings, and zapressovyvat it instead of the old. Installed in place of the plastic casing. The Main plus repair – no need for pressing and extrusion, which requires special tools. However, the repair will be effective only if the bearing is not much better. For a characteristic rustle this action will not save, because the production of the bearing is already beyond the norm.
Today, there are several leading manufacturers:
The Average cost of these items is from one to two thousand rubles depending on size. Used cars Japanese, German, American and French production.
So we figured out how to replacing the bearing of the compressor of the air conditioner. It is Worth noting that many drivers prefer to use the services of STO in this case. And for good reason. First, it is the presence of a special press. And secondly – the need for refilling the freon, which to produce at home certainly will not work.
