Honeywell 7616BR Motor Crank Arm Assembly

The Honeywell 7616BR is a replacement crank arm assembly specifically designed for Modutrol IV Motors, in commercial HVAC systems. It's not a complete motor, but a crucial component that attaches to the motor shaft and converts the motor's rotation into usable movement. While the voltage specifications (170-265 VAC) indicate a wider range than typical household current, the 50Hz frequency suggests it's primarily intended for use in regions outside of North America. The crank arm itself is a simple but important part. The motor shaft rotates, and the crank arm, securely fastened to the shaft, translates that rotation into an oscillating motion. This oscillating motion is then transferred to the damper or valve linkage within the HVAC system. The 1/2 horsepower (HP) rating refers to the motor it's designed for, indicating compatibility with Modutrol IV motors of that power class. By replacing a worn or damaged crank arm, the Honeywell 7616BR restores proper function to your Modutrol IV motor. This translates into precise control of dampers or valves within the HVAC system, ensuring efficient regulation of airflow throughout a commercial building. At an ultralight weight of just 0.21 pounds, the crank arm itself is easy to handle and install during maintenance procedures. Be sure to consult your specific HVAC system's manual for compatibility information before ordering this replacement part.
