Heil Quaker ICP 1175315 Pulley

Ensure optimal airflow performance and reliable torque transmission with the Heil Quaker ICP 1175315 Blower Pulley. This genuine OEM replacement part is engineered for high-demand HVACR applications, featuring a precise 1-inch bore and a 7-inch outer diameter. Constructed with a fixed bore design, this 7x1 blower pulley facilitates the critical transfer of rotational energy from the drive belt to the blower wheel, maintaining consistent static pressure across your system. As a FENNER DRIVES product (ALTCODE: AFD74), it is specifically designed to meet the rigorous tolerances required for Heil, Tempstar, and Comfortmaker rooftop units and air handlers.

Proper alignment of the fan motor pulley is essential to prevent premature belt shredding and excessive amp draw. This domestic accessory includes integrated set screws for a secure lock on the 1" shaft, ensuring the HVAC blower assembly operates without slippage or vibration issues. Whether you are replacing a seized 1170566 pulley or performing seasonal maintenance on an RGS120 layout, using International Comfort Products original components restores factory-spec airflow and heat exchange efficiency.

Key Benefits for Contractors:

• Precision Machined: 1" bore ensures a tight, vibration-free fit on standard blower motor shafts.
• System Efficiency: Restores original blower RPM for proper CFM delivery and balanced ventilation.
• Durable Construction: Black-finished industrial-grade material resists wear in corrosive or high-temperature environments.
• Universal ICP Compatibility: Direct drop-in for multiple Heil Quaker and Arcoaire residential and commercial models.
• Genuine OEM: Guarantees the correct weight and balance to prevent bearing fatigue in the blower housing.

Common Questions & Technical Insights:

• How do I ensure this pulley is properly aligned? Use a straight edge across both the motor sheave and this 7-inch pulley to ensure the belt tracks straight. Misalignment is the leading cause of black dust buildup and belt failure.
• Will this fit a 7/8" shaft? No, this is a fixed 1-inch bore. Attempting to sleeve or modify the bore can cause dangerous imbalances.
• Is this compatible with variable speed motors? Yes, as long as the motor shaft and belt profile (typically A or B section V-belts) match the pulley's groove dimensions.
