15:14. Plug of coupling and pulley of the compressor of the conditioner

Coupling and pulley of the compressor of the conditioner

1 – expansion plug;
2 – pulley and bearing;
3 – excitement coil;
4 – socket of the electromagnetic coupling;
5 – sealing ring;
6 – knot of pipelines;
7 – bolt, 16,3–26,6 N • m;
8 – plate;
9 – conditioner compressor;
10 – consolidation of a shaft;
11 – sealing ring;
12 – consolidation;
13 – lock ring;
14 – disk and plug;
15 – bolt, 10,2–15,3 N • m.


1. Turn out a bolt of fastening of the plug of coupling, at the same time a special key 09977–34000 hold the plug from a provorachivaniye.
2. Remove the plug of coupling and laying from a compressor shaft. If the plug is not removed, screw a bolt on M8 in an opening of a shaft of the plug and for a bolt remove the plug.
3. Remove a lock ring.
4. Remove a pulley and the bearing from a compressor shaft.


1. Clear the working surface of the bearing of a pulley of the compressor and remove traces of dirt and corrosion.
2. Establish a pulley and the bearing on a compressor shaft.
3. Establish a lock ring.
4. Arrange one laying of the expansion plug of nominal thickness in a flute of the plug and install the plug on a compressor shaft.
5. Install the new plug and fix it by a bolt, having tightened it the required moment.

Inhaling moment: 10,2–15,3 N • m


Do not use pneumatic tools.

6. The probe check a gap of coupling of the compressor of the conditioner between the plug of coupling and a pulley. Check a gap in three points on pulley perimeter.

Gap: 0,35–0,75 mm

7. If the gap differs from demanded, adjust it, having established laying of the corresponding thickness.
