1 - | Hexagon nut |
q | To unfasten and tighten the hexagon nut, hold the pulley in position with a commercially available strap wrench (with fabric strap). |
q | Before screwing on, remove the old locking fluid from the hexagon nut thread and the thread of the air conditioner compressor shaft. |
q | Apply locking fluid when fitting the hexagon nut (e.g. D 000 600 A2) → Electronic parts catalogue. |
q | Tightening torque 25 Nm |
2 - | Bolt |
q | To slacken off and tighten the bolts, hold the pulley in position with a commercially available strap wrench (with fabric strap). |
q | Before screwing in, remove the old locking fluid from the bolt threads and the threads of the pulley. |
q | Apply locking fluid when fitting the bolts (e.g. D 000 600 A2) → Electronic parts catalogue. |
q | Tightening torque 4.5 Nm |
3 - | Drive plate |
q | With overload safeguard; tripped in the event of excessive torque (e.g. stiff air conditioner compressor) and the pulley just free-wheels without driving the air conditioner compressor. |
q | With rubber element for decoupling the pulley from the air conditioner compressor drive shaft and for damping vibration and noise. |
4 - | Washer |
5 - | Circlip |
q | Replace |
q | Fit in correct position with the bevelled side -A- facing away from the air conditioner compressor (flat side towards compressor). |
q | On fitting the circlip, take care not to bend it open more than necessary. |
6 - | Pulley |
q | Clean the air conditioner compressor flange before fitting the pulley. |
7 - | Air conditioner compressor |
q | Different models may be fitted depending on the engine version and country version of the vehicle → Electronic parts catalogue. |

1 - | Hexagon nut |
Note
A plastic cap is additionally fitted to protect the thread of the compressor shaft (this cap is not shown in the illustration). |
q | To unfasten and tighten the hexagon nut, hold the pulley in position with a commercially available strap wrench (with fabric strap). |
q | Before screwing on, remove the old locking fluid from the hexagon nut thread and the thread of the air conditioner compressor shaft. |
q | Apply locking fluid when fitting the hexagon nut / bolt (e.g. D 000 600 A2) → Electronic parts catalogue. |

2 - | Bolt |
q | To slacken off and tighten the bolts, hold the pulley in position with a commercially available strap wrench (with fabric strap). |
q | Tightening torque 12 Nm |
q | Before screwing in, remove the old locking fluid from the bolt threads and the threads of the pulley. |
q | Apply locking fluid when fitting the bolts (e.g. D 000 600 A2) → Electronic parts catalogue. |
3 - | Drive plate |
q | With overload safeguard (attachment of spring elements); this is tripped in the event of excessive torque (e.g. stiff air conditioner compressor) and the pulley just free-wheels without driving the air conditioner compressor. |
q | The spring elements of the drive plate dampen vibrations and reduce noise. |
4 - | Circlip |
q | Replace |
q | Fit in correct position with the bevelled side -A- facing away from the air conditioner compressor (flat side towards compressor). |
q | On fitting the circlip, take care not to bend it open more than necessary. |
5 - | Pulley |
q | Clean the air conditioner compressor flange before fitting the pulley. |
q | With rubber elements -B- and threaded plates -C- for isolating the pulley from the air conditioner compressor drive shaft (the rubber elements dampen vibrations and reduce noise). |
Note
Depending on the version, the threaded plates -C- may also be linked by way of a ring. |
6 - | Air conditioner compressor |
q | Different models may be fitted depending on the engine version and country version of the vehicle → Electronic parts catalogue. |
