7. Compressor assembly
Withdrawal
1. If the compressor is in a partially open state, start the engine at idle and turn on the air conditioning system for a few minutes, then stop the engine.
2. Disconnect the negative plug from the storage battery.
3. Extract the refrigerant using the drain and charge unit.
4. Loosen the drive belt.
5. Turn away bolts then disconnect inlet (A) and graduation (IN) lines from the compressor. Plug or cover the lines immediately after disconnecting them to prevent atmospheric moisture and dust from entering them.
6. Disconnect the compressor clutch connector, unscrew the 3 mounting bolts and remove the compressor (A).
Installation
1. Check the length of the compressor mounting bolts, then tighten them in the order A->B->C.
Note: Tightening torque: 20.0 - 32.9 Nm.
2. Installation is made in an order, the return to an order of removal. In doing so, pay attention to the following features:
When installing a new compressor, drain all refrigerant oil from the old compressor and measure its volume. Subtract the volume of oil drained from 120 cm3 to obtain the volume of oil to be drained from the new compressor (through the inlet).
Replace sealing rings with new ones; Apply a thin coat of refrigerant oil to them before installation. Be sure to use O-rings designed for R-134a refrigerant to prevent leaks.
To avoid contamination, do not pour drained oil back into the container, never mix it with other oils.
Immediately after using the oil, place the lid on the container and tighten it tightly to prevent moisture from entering.
Do not allow refrigerant oil to get on the surface of the car, this may damage the paintwork. If refrigerant oil gets on a painted surface, it must be washed off immediately with water.
Adjust the drive belt tension.
Prime the system and check its performance.
Checking the technical condition
1. Inspect the galvanized parts of the disc and hub (A) assembly for discoloration, peeling, or other damage. Replace clutch kit if damaged.
2. Check pulley bearings (IN) for play and jamming by turning the pulley by hand. If there is excessive play/seizure or noise, replace the clutch kit.
3. Check the operation of the magnetic clutch. Connect compressor leads to positive (+) battery terminal, and the compressor housing - with a negative terminal (-). Check for noise generated during clutch operation.
Disassembly
1. Remove the front left wheel (A).
2. Remove the side cover (A) engine.
3. Remove the central bolt (A), holding the disc and hub assembly with a special tool (09977-29000).
Note: Tightening torque: 10-15 Nm.
4. Remove the assembly (A) discs and hubs and shims (clearance adjustment washers). Don't lose these pads.
5. Remove retaining ring (A), then remove the pulley (IN).
Note:
Be careful not to damage the pulley (IN) and compressor during removal/installation.
Removed retaining ring (A) must be replaced with a new one.
6. Remove retaining ring (IN), then remove the exciter coil (WITH). Be careful not to damage the coil and compressor.
7. Install the compressor clutch in the reverse order of removal. In doing so, pay attention to the following features.
A. Clean the friction surfaces of the pulley and compressor with a non-petroleum based solvent.
B. Install new circlips making sure they are properly seated in the groove.
C. After assembling the pulley, make sure it rotates smoothly.
