The generator and cooling system pump drive belt tension
(Fig. 9.6.) is provided by automatic tension mechanism 2. In
the operation process, the automatic tension mechanism does
not require servicing or adjustment.
Fan and steering system hydraulic pump drive belt tension 15
(Fig. 9.6) is performed by displacing pump 12, for which it is
necessary: to loosen bolts 13, adjust the drive belt tension by
adjustment bolt 14 and move the pump along the rails. Tighten
bolts 13.
In motor vehicles equipped with an air conditioner the
aggregates drive is performed by the same belt. Its tension is
adjusted automatically (Fig. 9.7). It is necessary to check belt
condition during the operation process. Upon detection of its
substantial looseness, the GUR pump placement adjustment is
Fig. 9.7. Accessory drive belt:
1 — automatic tensioning mechanism; 2 — auxiliary Idle pulleys/guide rollers;
3 — conditioner compressor pulley; 4 — alternator pulley; 5 — fan pulley; 6 —
