Removal steps

  1. Flexible suction hose connection
  2. Flexible discharge hose connection
  3. O-ring
  4. A/C compressor and clutch assembly
  5. A/C compressor bracket A
  6. A/C compressor bracket B

NOTE: The service points which are not described are the same as before.

REMOVAL SERVICE POINTS

FLEXIBLE DISCHARGE HOSE / FLEXIBLE SUCTION HOSE DISCONNECTION

CAUTION As the compressor oil and receiver are highly moisture absorbent, use a non-porous material to plug the hose and nipples.

To prevent the entry of dust or other foreign bodies, plug the dismantled hoses and compressor nipples.

A/C COMPRESSOR REMOVAL

Take care not to spill any compressor oil when removing the compressor.

INSTALLATION SERVICE POINT

A/C COMPRESSOR AND CLUTCH ASSEMBLY INSTALLATION

If a new compressor is installed, first adjust the amount of oil according to the procedures described below, and then install the compressor.

1. Measure the amount [X cm3 (X fl.oz) of oil within the removed compressor.

2. Drain (from the new compressor) the amount of oil calculated according to the following formula, and then install the new compressor.

New compressor oil amount = 70cm3 (2.4 fl.oz)

70 cm3 − X cm3 = Y cm3 (2.4 fl.oz. − X fl.oz. = Y fl.oz)

NOTE: Y cm3 (Y fl.oz) indicates the amount of oil in the refrigerant line, the condenser, the evaporator, etc.

NOTE: When replacing the following parts at the same times as the compressor, subtract the rated oil amount of each part from Y cm3 (Y fl.oz) and discharge from the new compressor.

3. Tighten A/C compressor and clutch assembly mounting bolts to the specified torque in the order of number shown in the figure.

Tightening torque: 23 +- 6 N*m

INSPECTION

A/C COMPRESSOR CLUTCH OPERATION CHECK

Connect the compressor connector terminal to the battery positive (+) terminal and ground the battery's negative (-) terminal to the compressor unit. At that time, the A/C compressor clutch should make a definite operating sound.

ROTOR REMOVAL

CAUTION

Rotor can be removed by hand, but if it is difficult to remove it, use the guide (MB992623) and the side bearing puller (MB990810) as shown.

ASSEMBLY SERVICE POINTS

A/C COMPRESSOR HIGH PRESSURE RELIEF VALVE INSTALLATION

CAUTION Be careful not to damage the O-ring when installing the high-pressure relief valve. Apply the specified refrigerating machine oil the high-pressure relief valve mounting hole before installation

Check that O-ring is installed to the high-pressure relief and use the adjust torque wrench to install the high-pressure relief valve to the main body of the compressor.

FIELD CORE ATTACHMENT

Line up the pin hole on the compressor unit with the field core projection and attach.

ROTOR INSTALLATION

CAUTION If the outer wheel side of the rotor is pushed, an abnormal noise can be generated because the inside of the rotor is damaged, therefore, always push the inner wheel side.

Install the rotor while pushing the inner wheel side slowly using the pusher (MB992624) and the guide (MB992623).

NOTE: Insert the rotor in a direction perpendicular to the A/C compressor.

AIR GAP ADJUSTMENT

Check whether or not the air gap of the clutch is within the standard value.

Standard value: 0.25 − 0.45 mm (0.010 − 0.017 inch)

NOTE: If there is a deviation of the air gap from the standard value, make the necessary adjustment by adjusting the number of shims.

INSPECTION

A/C REFRIGERANT TEMPERATURE SWITCH

CAUTION Do not heat more than necessary.

1. Dip the metal part of the A/C refrigerant temperature switch into engine oil and increase the oil temperature using a gas burner or similar.
