| 1. Establish manometers to the highway. |
| 2. Check a tension of a belt of a drive of the compressor. |
| 3. Start the engine, leave to work at frequency of rotation of a cranked shaft of 1500 mines-1. |
4. Check the compressor on existence of the following defects:
– the low indication of a manometer, however, not below demanded, and the high indication of a manometer, however, not above the demanded;
– metal sound;
– leaks from shaft consolidation.
In the presence of any defect it is necessary to repair the compressor. |
5. Check the electromagnetic coupling:
– lift the car;
– examine press a disk and a rotor on availability of greasing on them;
– check the coupling bearing on existence of noise and leakage of lubricant;
– by an ohmmeter measure resistance of the coil.
If resistance differs from demanded, replace the coil:
– an additional wire submit tension from the positive plug of the storage battery on contact of the socket of the coil, thus the electromagnetic coupling should be raised.
If the electromagnetic coupling is not raised, replace the coil. Resistance of the coil: 3,11±0,08 Ohm at 12,8 In and 20°C
