A/C Compressor and Bracket, Engine Codes: BAC, BLK, BPE and BPD
A/C Compressor and Bracket, Engine Codes: BAC, BLK, BPE and BPD
Special tools, testers and auxiliary items required
• Torque Wrench (V.A.G 1331/)
• A/C Service Station (VAS 6007A)
CAUTION!
There is a danger of ice-up.
Refrigerant leaks out if refrigerant circuit is not discharged.
Refrigerant must be extracted before opening the refrigerant circuit. If the refrigerant circuit is not opened within 10 minutes after extracting it, pressure may build up in the circuit again. The refrigerant must be extracted again.
• The auxiliary component bracket for A/C compressor and ancillary parts can be removed and installed without opening the refrigerant circuit.
1 A/C Compressor
• Remove refrigerant lines from A/C compressor. The bolts have different lengths.
- Disconnect the connector on the A/C compressor.
• Make sure the connector is secure on the A/C compressor.
• The bolt tightening specification is 20 ± 3 Nm.
• Be careful of the alignment sleeves - 7 - between the A/C compressor, sub-assembly bracket and engine block - 8 -.
2 Torsion elastic clutch
• Between A/C compressor and power steering pump
3 Screws
• 20 Nm
• Quantity: 2
• Be careful of the alignment sleeves - 7 - between sub-assembly bracket - 8 - and engine block.
4 Screws
• 20 Nm
• Quantity: 3
5 Overload protection
• Function: Disconnects connection between A/C compressor and power steering vane pump when A/C compressor is blocked.
6 Take-up with free-running hub
• Removing and installing, refer to=> [ Mount with Freewheel on A/C Compressor ] Mount with Freewheel on A/C Compressor
• Function: At a change in engine RPM, A/C compressor RPM can be adapted better and torsion elastic clutch is under less load.
7 Dowel sleeves
• Quantity: 4
• Ensure proper seating between auxiliary component bracket, engine block and A/C compressor
8 Auxiliary component bracket
• Number on auxiliary component bracket: 070 260 885 A
Securing A/C compressor to body
If A/C compressor is removed and refrigerant circuit not opened, A/C compressor must be secure to body using appropriate material, a welding wire for example.
Make sure that refrigerant hoses remain on A/C compressor without tension for this.
