Check and compressor and K/V magnetic coupling replacement Check
|
|
- Start the engine and make sure of lack of a metal sound from the compressor at inclusion К/В. If necessary replace compressor assembly. If abnormal noise at switching off is audible To/in, replace the magnetic coupling.
- Having the necessary equipment and skills, check pressure of a coolant and compare it to requirements of Specifications of the Head of System of cooling of the engine, heating, ventilation and air conditioning.
|
|
-
Separate the socket of the sensor of blocking of the compressor, measure resistance between its contacts 1 and 2 and compare the received result to requirements of Specifications of the Head of System of cooling of the engine, heating, ventilation and air conditioning. If necessary replace compressor assembly. Connect a negative wire from the battery to the sensor case, and positive – to contact 3, – the magnetic coupling thus should be activated. Otherwise replace the coupling.
|
- Make sure of absence of leakages of a coolant through a control epiploon. If necessary replace the compressor assembled.
- Visually check tightness of the bearing of the coupling. Make sure of lack of traces of oil on a press plate.

Replacement
Components of assembly and To/in compressor installation
|
|
- To Zagustita the engine on single turns at included To/in, let's to it work 10 minutes and switch off the engine.
- Disconnect a negative wire from the storage battery.
- Discharge To/in system and remove a driving belt of the generator and the To/in compressor (see. Section Check of a condition and replacement of belts of a drive of auxiliary units).
|
|
-
Turn out a bolt with a nut and disconnect soaking-up hoses. After a detachment as soon as possible закупорьте open branch pipes.
|
- Remove the generator (see. Head of System of electric equipment of the engine).
|
|
-
Separate the socket of electroconducting of the compressor, turn out two bolts, a nut and remove an arm of adjustment of a tension of a driving belt.
|
- Turn out three bolts and remove the compressor.
- Installation are made as it should be, the return to an order of dismantle of components.
