Overview - Belt Pulley, Sanden A/C Compressor
1 - Nut 25 Nm
Note
To protect the A/C compressor input shaft threads, they may be covered with a plastic cap (the plastic cap is not illustrated).
– Hold the belt pulley securely with a commercially available oil filter band wrench to loosen and tighten the hex nut.
– The thread of the nut, which was screwed in with locking compound, must be cleaned (for example, using a thread tap). Otherwise, there is a risk that the input shaft will break off during assembly.
– Clean the threads of the A/C compressor input shaft with a wire brush.
– Insert the nut with locking compound. Locking fluid. Refer to the ⇒ Electronic Parts Catalog (
ETKA).
2 - Bolt 12 Nm
– Hold the belt pulley securely with a commercially available oil filter band wrench to loosen and tighten the bolts.
– The threaded bolt holes, into which the self-locking bolts or bolts with locking compound are screwed, must be cleaned (for example with a thread tap). Otherwise there is the risk that the bolts could break
off when they are removed again.
– Clean the threads of the bolts that were installed with locking fluid using a wire brush. Then insert the bolts with locking fluid. Locking fluid. Refer to the ⇒ Electronic Parts Catalog (ETKA).
3 - 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
4 - 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
5 - 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
Note
The threaded plates can also be connected to each other by a ring, depending on the version.
♦ 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 ⇒ Electronic Parts Catalog (ETKA).
6 - A/C Compressor
Clean the A/C compressor input shaft before installing the belt pulley.
