Clean thread of nut which was tightened with locking fluid (e.g.
with a thread tap). If it is not cleaned, the drive shaft may be torn
off when it is removed the next time. |

| – |
Clean threaded holes in which self-locking bolts or bolts with
locking fluid where installed (e.g. with a thread tap). If the threads
are not cleaned, the bolts may be torn off when they are removed the
next time. |
| – |
Clean threads of bolts which are to be installed with locking fluid
using a wire brush. Then install bolts with locking fluid. Locking fluid

| 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
