Case-IH® Compatible Rotor & Cleaning Fan Drive Speed Adjustment Motor
Maintain precise cab-controlled speed adjustments for your rotor and cleaning fan with this premium aftermarket motor and gearbox assembly. Specifically engineered for
early model Case IH® mid-series Axial-Flow combines, this high-torque 12V motor ensures smooth operation of your variable-speed drive systems.
This versatile unit drives the threaded mechanism that moves the sprocket on the variable-speed sheave, altering the effective diameter and belt tension to change rotor RPM. It is also used within the cleaning fan system to regulate airflow, allowing the operator to match fan speed to changing crop conditions directly from the cab while the separator is engaged.
