   Feeder Belt Tracking

   A - Feeder Belt

   B - Drive Roller (Left-hand End)

   C - Drive Roller (Right-hand End)

   D - Grooves in Drive Roller

   E - Grooves in Tensioning Roller

   Check feeder belt (A) for proper tracking. There are two indications that the feeder belt tension is not properly adjusted:
   1. Belt is not centered on drive roller and tracks toward one side.
      1. From beneath platform, observe position of edge of feeder belt in relation to left-hand end of drive roller (B). Repeat at right-hand end of drive roller (C).
      2. Verify that distance from belt edge to end of roller is approximately the same at both ends and that black rubber covering on roller does not show beyond edge of belt.
   2. NOTE: The inner side of the feeder belt has two V-shaped guide treads protruding from the surface of the belt approximately 23 inches from each edge of the belt. These two treads extend the length of the belt and ride in grooves in the drive roller and tensioning roller.
      Guide treads on inner side of belt are tracking out of grooves in drive roller and tensioning roller.
      1. From top of platform, check feeder belt (A) for bulging or signs that guide treads on belt are tracking out of grooves in drive roller (D).
      2. Check for signs that guide treads are tracking out of grooves in tensioning roller (E).
