3.12.3. Adjustment of a tension of a belt of the drive of the pump


Fig. 3-61. Scheme of check of a tension of a belt of the drive of the pump

The tension of a belt is checked by its deflection between pulleys of the generator and pump or between pulleys of the pump and a bent shaft. At a normal tension of a belt the deflection And (fig. 3-61) under effort of 98 N (10 kgfs) has to be within 10–15 mm, and a deflection In — within 12–17 mm.
Дпя increases in a tension of a belt, having weakened nuts of fastening of the generator, displace it from the engine and tighten nuts.
