Honeywell 7617ADW Crank Arm

The Honeywell 7617ADW Crank Arm is a heavy-duty, field-adjustable linkage component engineered specifically for Modutrol IV motors. As the professional-grade direct replacement for the 4074ELY, this crank arm ensures precise torque transmission and stroke adjustment in commercial damper actuators and valve linkage assemblies. Designed for high-cycle reliability, the 7617ADW allows for variable radius settings to fine-tune the mechanical advantage and stroke length of your HVAC ventilation systems. It features a robust construction that minimizes shaft slippage and maintains calibration under thermal loads. When performing actuator maintenance or troubleshooting damper linkage kits, using various mounting holes on the arm permits exact alignment with the driven load. This compatibility with Honeywell Modutrol motors ensures that industrial HVAC controls operate with minimal hysteresis, providing the precision required for tight air-handling sequence requirements.

• Precise Stroke Adjustment: Adjustable radius allows for exact movement control of dampers and valves.
• Direct OEM Replacement: Replaces the 4074ELY without requiring modification to existing Modutrol IV setups.
• Enhanced Durability: Machined to withstand the high-torque output of series 61, 62, 71, 72, and 90 motors.
• Field Versatility: Multiple attachment points facilitate easy HVAC linkage assembly in tight mechanical spaces.
• Reliable Shaft Connection: Designed for a secure fit on the motor drive shaft to prevent mechanical drift over time.

Is the Honeywell 7617ADW compatible with older Honeywell motors?
The 7617ADW is specifically designed for the Modutrol IV series. While it may fit some legacy shafts, it is the standard replacement crank arm for modern Mod motors and is the primary drop-in for the 4074ELY.

How do I adjust the stroke length on this crank arm?
Stroke length is dictated by the hole selection on the arm. Moving the linkage pin closer to the shaft center reduces the stroke but increases force, while moving it outward increases the travel distance.

Does this arm include the ball joint and pushrod?
This part number refers specifically to the crank arm. If your actuator linkage requires the ball joints or rods, those must be sourced separately or reused from the previous assembly.
