Removal, service and To/in compressor installation

Air central air constantly is under a high pressure. At all do not disconnect refrigerator lines and do not remove any components of system, previously without having executed a discharge of the last. The discharge of central air of air should be made by strengths of the skilled expert in the conditions of a car-care center workshop. At a rassoyedineniye of refrigerator lines surely put on goggles!

At replacement of components of central air of air the certain amount of replaceable refrigerator oil necessary for filling of volume of new knot is required. Use only the oil good for the use in R-134a systems (attentively study a label on the container).

 PERFORMANCE ORDER

1. Make a discharge of central air of air in the conditions of a specialized workshop.
2. Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for audiosystem input in action!

3. Cock the parking brake, prop up back wheels protivootkatny boots, then поддомкратьте a front of the car and establish it on props.
4. Remove a driving belt of the compressor (see. Head of Control and routine maintenance).

5. Disconnect from the compressor refrigerator lines. At once закупорьте the open ends of tubes and unions in order to avoid hit in dirt and moisture system.

6. Disconnect from the compressor electroconducting, then give fixing bolts and remove assembly from a basic arm.

The top fixing bolts can be turned out not till the end are left in compressor assembly before its extraction from the car.

Service

 PERFORMANCE ORDER

On considered models of cars one of three types of К/В compressors is used.

Replacement of the coupling of coupling of the compressor

 PERFORMANCE ORDER

1. Turn out the central bolt, having stopped a coupling disk a wrench. The coupling can be removed by means of a special ex-tractor.

2. Bend down a tag of a lock washer, give a lock-nut and remove a pulley.

3. If on an interfaced surface signs of damage or overheat traces are visible, the leading disk of the coupling and a pulley should be replaced.
4. Before installation wipe an interfaced surface of a pulley solvent.
5. Check a spiral condition, - pay attention to existence of signs of weakening of contact and isolation damage.

6. At installation it is necessary to adjust a gap between a disk and a pulley by selection of adjusting washers, - use a measuring instrument of gaps between electrodes of spark plugs.

7. At replacement of the coupling of coupling of the compressor do not forget to make its running in, - the compressor should be switched on not less than 30 times.
8. In the course of a running in there is a building of a torque of the coupling. Do not allow hit in the compressor of extraneous materials.

INSTALLATION

 PERFORMANCE ORDER

1. Do not forget to transfer the coupling coupling from the old compressor on the new.
2. Add in system necessary amount of fresh refrigerator oil, proceeding from the following data:

a) Merge a coolant from the compressor removed from the car and measure its volume;
b) Merge a coolant present at new assembly;
c) If the amount of the oil merged from the old block made 90 ÷ 150 ml, fill in in the new compressor the same quantity of a fresh coolant;
d) If from the old compressor less than 90 ml of oil were merged, fill in in new 90 ml;
e) If the amount of the oil merged from the old block exceeded 150 ml, it is necessary to fill in in new assembly of 150 ml of a coolant.
3. Installation is made upside-down. Do not forget to replace sealing rings of shtutserny connections of refrigerator lines. Before installation of a ring it is necessary to grease with refrigerator oil. Remark: Do not forget to plant in the compressor two top fixing bolts before new assembly will be put on the car.
4. Make a charging of system and its check on leaks in the conditions of a specialized workshop.
