Tecumseh 51528-3 Fan Blade

The Tecumseh 51528-3 Fan Blade is a critical component for maintaining head pressure and ensuring optimal heat transfer in commercial and residential HVACR refrigeration systems. Engineered with an 18-inch diameter and a 3-blade configuration, this aluminum propeller is designed for high-efficiency operation in condenser fan motor assemblies. It features a clockwise (CW) rotation (viewed from the discharge side) and a 1/2-inch bore size, making it a direct replacement for many Tecumseh condensing units and outdoor coils. With a 23-degree pitch, this blade provides the necessary CFM to prevent compressor overheating and maintain system stability during high ambient conditions.

For field technicians, matching the 51528-3 fan blade to the original specs is vital to avoid motor burnout or excessive vibration. This blade is built for durability and precision balance, ensuring quiet operation and a long service life for refrigeration unit parts. Whether you are performing a seasonal PM or an emergency repair, verifying the rotation and bore diameter ensures this OEM replacement fan blade will restore the factory-spec airflow required for efficient condenser cooling.

Key Benefits:

• Optimized Airflow: The 18-inch 3-blade design delivers consistent static pressure for condensing unit airflow.
• Universal Fit: Standard 1/2-inch hub compatible with most 1/6 HP to 1/3 HP condenser fan motors.
• OEM Reliability: Genuine Tecumseh refrigeration part ensures exact fitment and avoids the balance issues of generic propellers.
• Corrosion Resistance: High-grade aluminum construction prevents rust in harsh outdoor condenser environments.

Common Questions:

• How do I confirm the rotation of the 51528-3? This blade is a clockwise (CW) rotation. Always verify the rotation by looking at the discharge side of the blade or the motor's lead-end to ensure proper draw-through or blow-through air patterns.
• Is this blade compatible with other HVAC brands? While designed specifically for Tecumseh units, it can serve as a replacement in any system requiring an 18" diameter 3-blade CW propeller with a 1/2" bore.
• Does it include the hub set screw? Most Tecumseh fan blades come with a pre-installed set screw in the hub for immediate mounting to the motor shaft.
