Belt tension adjustment
1. If the main drive belt deflects more than
1
/
4
”, tighten the belt by loosening the four
engine nuts along with the lock nut on the adjustment bolt and turning the
adjustment bolt clockwise until the belt is within the specified range. Then re-tighten
the four engine nuts and the lock nut on the adjustment bolt.
2. The secondary belt has an automatic belt tensioner. The tension is created by a
spring connecting a tensioner pulley to a fixed hitch plate with 2 positions (see fig.
17). Upon delivery, the spring is located in the first position. When the belt stretches
after use, adjust the tension by relocating the spring in the other hole. If the belt has
stretched to the point that the belt is not tight enough even in the second hole, then it
is necessary to replace the belt.
