Page 22: Removing Rotor Gears
Disassembling the Meter 3. When all the screws and bolts have been removed, remove the weldment cover. This exposes the inside of the weldment assembly and provides access to the meter assembly. The meter assembly is held in place by 4 bolts on the inlet side of the meter. This can be either side of the meter depending on the direction of flow. - Page 23 Disassembling the Meter 6. Keeping the spare displacement gear between the right rotor gear and blocking gear, use the allen wrench to loosen the screw of the right rotor gear assembly. 7. To loosen the screw of the blocking rotor gear, move the spare displacement rotor gear to between the left rotor gear and the blocking rotor gear to prevent the gears from moving.
