Compressor pulley: replacing
  Note
t  Depending on the design of the compressor and the engine version, different versions of the pulley are fitted → Parts catalogue.
t  Disassemble and reassemble the compressor pulley → Chapter
   
1 - Screw
q   Replace
q   Tightening torque: 20 Nm
q   Loosening and tightening → Chapter
  Note
t  Use the screw you removed to adjust the clearance.
t  Only place the new screw after establishing the clearance dimension (due to the threat fixing agent).
2 - Drive plate
q   Different versions → Parts catalogue
q   Removing and fitting → Chapter
q   Activated for excess torque (for example if the compressor becomes difficult to power).
q   Check and adjust the clearance between the rubber element of the pulley and the drive plate → Chapter.
3 - Spacing washers to adjust the clearance.
q   Check and adjust the clearance between the rubber element of the pulley and the drive plate → Chapter.
q   Clearance: 0.5 +/– 0.2 mm
q   Use 3 washers maximum.
  Note
t  If the clearance is very small even after fitting a maximum of 3 washers, check the pulley and the bracket in the compressor.
t  The clearance must be within the permitted tolerance all the way around the drive plate (all 4 measurement points).
4 - Circlip
q   Replace
q   Fit on the correct side (flat side facing the compressor)
q   Removing and fitting → Chapter
5 - Belt pulley
q   The rubber element acts in case of excess torque (in case the compressor becomes difficult to power) and the pulley moves freely without powering the compressor.
q   Different versions → Parts catalogue
q   Removing and fitting → Chapter
q   Check and adjust the clearance between the rubber element of the pulley and the drive plate → Chapter.
  Note
Under certain conditions (for example, engine trouble) the rubber element may be activated even if there is no problem with the compressor or the refrigerant circuit.
6 - Compressor
q   Different types are fitted depending on the engine specifications (and the vehicle country type). → Parts catalogue
