Rotork IQ3 Mod 1B Centre Column and Worm Wheel Assembly is the replacement gearcase component that pairs the center column with a matched wormwheel to drive the IQ3 actuator’s output. This assembly is offered in at least two gear ratios for IQ70-95 configurations: 15:1 (WIQ82786) and 60:1 (WIQ82785), enabling different torque and speed characteristics for slow, high-torque operation. The kit includes the center column, wormshaft, wormwheel, and torque-spring pack as part of the complete gearcase assembly for the IQ3 Mod 1B configuration.
