Overview - Belt Pulley, SANDEN A/C Compressor

- Nut
- To protect the input shaft threads, this is also covered with a plastic cap (the plastic cap is not pictured).
- Hold the belt pulley securely with a commercially available oil filter band wrench to loosen and tighten the hex nut.
- The thread on the nut, which was installed with locking fluid, must be cleaned (for example, with a thread tap). Otherwise, there is the risk that the input shaft will shear off during another removal.
- Clean the threads on the A/C compressor input shaft with a wire brush.
- Insert the nut with locking fluid. Refer to Parts Information for the locking fluid.
- 25 Nm
- Bolt
- Quantity: 3
- Hold the belt pulley securely with a commercially available oil filter band wrench to loosen and tighten the bolts.
- Threaded holes, in which self-locking screws or bolts with locking fluid were installed, must be cleaned (for example, with a thread tap), otherwise there is a risk that the bolts will break during another removal.
- Bolt threads that are installed with locking fluid must be cleaned with a wire brush, then the bolts must be inserted with locking fluid. Refer to Parts Information for locking fluid.
- 12 Nm
- Drive Plate
- The overload protection (securing spring elements), takes over when the torque is excessive (for example, if the A/C compressor runs with resistance) and the belt pulley runs freely without driving the A/C compressor.
- The drive plate spring elements dampen vibrations and noise
- Circlip
- Replace after removing
- Install on the proper side, beveled insertion edge -A- faces away from the A/C compressor; flat side faces the A/C compressor
- Belt Pulley
- With rubber elements -B- and threaded plates -C- for decoupling the belt pulley from A/C compressor input shaft, dampens vibrations and noises
- Depending on the version, the threaded plates can also be connected to each other by a ring.
- For "cold climate" vehicles (for example, central and northern Europe), A/C compressors with a smaller displacement can be installed. On these A/C compressors, the belt pulley is slightly different from the one illustrated here (the rubber elements -B- are, for example, not present). Refer to Parts Information.
- A/C Compressor
- Clean the A/C compressor input shaft before installing the belt pulley
