Since the generator has only one belt, you will not be able to use an adjacent belt as a reference. Place a
straightedge (a wrench, ruler, or other straight object) over the engine and generator pulley to use as a
reference line. Proceed as you did when checking the drive belt tension.
Since there is a generator belt adjusting screw, adjusting the belt tension of the generator belt is
somewhat easier than adjusting the drive belts. For the correct belt tensions, the O-ring should be
between the 5-to 7-pound marks.
If the belt tension is not right, loosen the locknut on the belt adjusting screw and the two capscrews on
the generator (Figure 16). Turn the adjusting screw clockwise to increase belt tension and counter-
clockwise to loosen belt tension. You may have to check a couple of times until you get the right belt
tension. Tighten the generator capscrews and belt adjusting screw locknut.
