Honeywell 4074EGR Crank Arm Assembly

The Honeywell 4074EGR is a mission-critical Crank Arm Assembly engineered for damper actuator applications in commercial and residential economizer systems. This heavy-duty linkage component is designed to facilitate the smooth conversion of rotary motion into linear motion, ensuring precise airflow control. As an industry-standard part, the 4074EGR is identical to the 4074EGR/U, providing a direct replacement for worn mechanical drive components. It is built to maintain tight tolerances and withstand the operational rigors required in ventilation and combustion air dampers.

This assembly is specifically compatible with Honeywell Actuator series including the M6415, M7215, M7415, M8405, and M8415. It also supports M6400, M7400, and M8400 models, making it a versatile HVAC accessory for your unit replacement or overhaul projects. Operating within a wide temperature range of -25°F to 125°F (-32°C to 52°C), this economizer crank arm ensures consistent performance across diverse environments. For contractors managing HVAC repair tasks, using genuine Honeywell parts like the 4074EGR is the only way to ensure proper motion transfer and long-term system reliability.

Key Benefits
