for Sprague Model 175 Gas Meters
Plastic Index with Metal Drive Foot
Step 7 – Route the sensor wire so that it
does not interfere with the magnet wheel
or the index gears. Hand tighten index
mounting screws. Gently move the 2-foot
hand to check for some free play to
insure that the register is not binding up.
Step 8 – Next, create an exit notch for the
sensor wire by cutting away a small piece
of the corner where the left hand edge of
the clear index cover meets the ridge at
the bottom of the meter head.
Step 9 – Secure the clear index cover to

safety, or security hardware onto the
clear index cover as required.
