U WARNING: Take care not to over-tighten the set screws to avoid damaging the index pointer
and pulse wheel.
The installed pulse wheel shall not move from the installed position, and cannot physically
contact the index face or other pointers on the index. If contact occurs, the index should be
replaced with an approved index.
6. Remove the shim and verify that the wheel rotates freely while remaining level with the index
surface.

7. Install the index onto the meter using the original screws. The meter's drive dog must be inserted
into a groove on the index drive mechanism as shown in Figure 9 - 13.
8. Confirm that the index’s center of rotation is aligned with the meter dog’s center of rotation.
Adjust the index alignment as needed. The magnet wheel center of rotation must be aligned
with the meter index drive mechanism center of rotation, shown by RED ARROWS in the
following photos. Tighten the index screws to a torque of 15 - 20 inch-pounds.
