Heil Quaker ICP 1175896 Blower Pulley

The Heil Quaker ICP 1175896 Blower Pulley is a precision-engineered OEM replacement part designed for industrial and residential HVAC air handlers. This fixed-bore pulley features a robust cast iron construction, ensuring long-term durability and resistance to thermal expansion under high-torque conditions. Engineered for a 5/8-inch shaft diameter, it provides a secure fit to maintain critical blower wheel RPM and optimal airflow velocity across the evaporator coil. When replacing ICP furnace parts, using this genuine drive sheave is essential for preventing premature V-belt wear and maintaining the exact static pressure specifications required by the system design. Proper alignment of this blower motor pulley is vital for reducing vibration and bearing load, extending the service life of the entire drive assembly. Whether you are performing a routine HVAC blower repair or troubleshooting a ventilation system efficiency issue, this component ensures the reliable mechanical power transmission necessary for consistent climate control performance.

• Durable Cast Iron Build: Engineered to withstand high-stress HVAC drive system demands without warping.
• Precise Bore Matching: Ensures a tight 5/8" fit to minimize shaft run-out and harmonic resonance.
• Optimized Belt Tracking: Precision-machined grooves reduce V-belt friction and heat buildup.
• Direct OEM Compatibility: Eliminates guesswork during Heil Quaker replacement installs, ensuring factory-spec performance.

What is the typical cause of pulley failure in these units?
Most failures result from pulley misalignment or improper belt tension, leading to groove scoring and reduced torque transmission efficiency.

Is this pulley compatible with adjustable pitch sheaves?
No, the 1175896 is a fixed-diameter pulley. If your application requires variable CFM adjustments, you must verify the fixed ratio meets your TESP requirements.

How do I ensure the set screw doesn't slip on the motor shaft?
Always align the set screw with the shaft keyway or flat and use a thread-locking compound to prevent loosening from high-start torque vibrations.
