A movement for a gauge instrument is mounted by a bracket (34) on the condition responsive element of the gauge for movement therewith. A shaft (36) carried by the bracket (34) rotatably supports a segment gear arm (40) which meshes with a pinion (42) on an output shaft 38. A second segment gear (60 min ) is freely rotatably mounted on the first segment gear (40) and meshes with the pinion (42) to apply a rotational drive to the pinion thereby eliminating backlash between the pinion and the first segment arm (40). A spring (66) biases the end of a fixed actuation (46) into engagement with the first segment arm (40) to eliminate backlash at this point. |
