Removal

PERFORMANCE ORDER

Change of the direction of rotation of the belt which was already in work can lead to its break.

Incline the tension device for weakening of a maple belt in the direction of an arrow on an accompanying illustration A.

Fix the tension device T10060 mandrel (an arrow on an accompanying illustration B).

Take off maple a belt.

Installation

PERFORMANCE ORDER

Check whether all units are reliably installed (the generator, the compressor, the pump).
Put on maple a belt according to a tag of the direction of rotation.
At cars with the conditioner in the last turn put on a belt the compressor.
