Perform the following steps if the index must be replaced:
Figure 4 - 8. Index Screw and Drive Details
1. Turn index screws (shown by red circles) counter clockwise enough to loosen and gently slide
the old index screw tabs from beneath the screws using a right-to-left motion.
2. Slide the replacement index screw tabs beneath the screws using a left-to-right motion as shown
in the photo at right in Figure 4 - 8.
3. Verify that the index drive mechanisms of both the bracket and index (red arrows) are aligned
and free to rotate without binding.
4. Itron recommends tightening the screws “hand-tight” or 6 to 12 inch-pounds. The Itron
specification is listed as “3 to 6 inch-pounds (after relaxation)” in their published documents.
Installing Back Mount Dial Wheels
Figure 4 - 9. Alignment Slots On Top of Each Wheel Half
1. Insert one screw into the notched dial wheel half.
2. If the dial wheel halves have alignment slots, position them so that the slots on each half are
aligned. Turn the screw until it begins to thread into the threaded bottom wheel half as shown in
the following figures.
