REPLACE IDLER BUSHINGS
Carbon-Graphite and Bronze (Consult Factory for Other Bushing Materials)
1. Remove the old bushing by pressing it out of the idler. It is not unusual for carbon graphite bushings to crack or break
apart during removal.
2. Inspect the idler bore for any damage. Any small scratches or nicks must be filed smooth before installing the new
bushing.
3. Press the new idler bushing into the idler leading with the tapered edge.
a. For models E1-2 thru E1-82 (Figure 1), the bushing is in its proper location when both ends of the bushing are flush or
slightly recessed from the idler face.
b. For models E1-133 and E1-222 (Figure 2), the bushings should protrude per the sketch.
