Adjusting the tension of the pump drive belt (VAZ-2121)

The belt tension is checked by its deflection between the generator and pump pulleys or between the pump and crankshaft pulleys. With normal belt tension, deflection A (Fig. 2-61) under a force of 98 N (10 kgf) should be within 10-15 mm, and deflection B within 12-17 mm.

To increase the belt tension, loosen the generator mounting nuts, move it away from the engine and tighten the nuts.
