Check and compressor and K/V magnetic coupling replacement

Check

 PERFORMANCE ORDER

  1. 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.
  2. 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.
  1. 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.
  1. Make sure of absence of leakages of a coolant through a control epiploon. If necessary replace the compressor assembled.
  2. Visually check tightness of the bearing of the coupling. Make sure of lack of traces of oil on a press plate.

 PERFORMANCE ORDER

  1. To Zagustita the engine on single turns at included To/in, let's to it work 10 minutes and switch off the engine.
  2. Disconnect a negative wire from the storage battery.
  3. 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).
  1. Turn out a bolt with a nut and disconnect soaking-up hoses. After a detachment as soon as possible закупорьте open branch pipes.
  1. Remove the generator (see. Head of System of electric equipment of the engine).
  1. 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.
  1. Turn out three bolts and remove the compressor.
  2. Installation are made as it should be, the return to an order of dismantle of components.
