1. By dropping plumb points, chalk line "A" on floor
   directly below and parallel to lathe spindle.
2. Drop plumb line from spindle at Center Line of
   widest wheel to be used. ("B")
3. From this point measure in toward lathe 7-3/4" ("C")
4. At this point, at right angles to line paralleling
   spindle, chalk a line. ("D")
5. Measure back along line "D" mounting distance
   as obtained from Table 1 and drill for 3/8" bolt. For
   installations using belts less than 118" long,
   mount idler so its base is parallel to belt.
6. Fasten idler at front bolt hole. Install wheel and belt. Apply light tension. Set idler shaft parallel to lathe spindle.
7. Drill rear bolt holes in center of slots, and install bolts.
8. With idler pulley in the neutral position (i.e. equal amount of spindle threads exposed on each side of arm), belt and wheel installed, jog motor and pivot idler slightly about front bolt until belt rides in exact center of pulley, then tighten all bolts.
9. Tighten shaft wing stud on top of arm.
10. Track belt on contact wheel.

INSTRUCTIONS FOR CHANGING IDLER FOR OPERATION ON OPPOSITE SIDE OF LATHE

1. Remove pulley shaft.
2. Remove shaft wing stud.
3. Remove pulley shaft plug under shaft wing stud.
4. Replace shaft from opposite side.
5. Replace pulley shaft plug.
