| With overload protection (mountings of spring elements). Deploys in
the event of excessive torque (e.g. if the air conditioner compressor
cannot rotate freely). The belt pulley then rotates without driving the
air conditioner compressor. |
| The spring elements of the drive plate absorb vibrations and noise. |
| Do not reverse when installing; chamfer -A-
faces away from air conditioner compressor (flat side towards air
conditioner compressor). |
| With rubber elements -B- and threaded
plates -C- for decoupling belt pulley from
air conditioner drive shaft (absorb vibrations and noise). |
Note
| Depending on design, the threaded plates may also be connected by
means of a ring. |
| “Cold country” vehicles (e.g. central and northern Europe) may be
fitted with air conditioner compressors with a smaller capacity. On
these air conditioner compressors, the pulley is slightly different to
the version shown here (e.g. no rubber elements

tread blocks → Fig.
that can cause increased tyre noise. The saw tooth is caused by
uneven deformation of the tread blocks in the tyre's contact
patch. Saw-tooth wear is more pronounce ...
Conicity
Conicity is caused by a slight offset of the tread and/or
the belt (amounting to a few tenths of a millimetre) relative to
the geometric centre of the tyre. Taper is not visible and
cannot be measured with equipment available in the workshop.
