York S1-001-07110-004 Key
The York S1-001-07110-004 Square Blower Key is a critical mechanical fastener designed to prevent rotational slippage between the blower motor shaft and the fan wheel. Measuring 1/4 inch by 6.375 inches, this genuine OEM part ensures precise power transmission in high-torque HVAC applications. Constructed from hardened steel, it is engineered to withstand the constant shear stresses of residential and light commercial air handlers, eliminating the common issue of rounded shafts or "loose wheel" vibration. For technicians servicing equipment like the BP240E54S4AAA1 or TGLS series units, using a precisely milled 6.3-inch blower key is essential to maintain industrial tolerances and avoid catastrophic assembly failure.
Key Benefits
- Precise 1/4" Square Profile: Ensures a zero-tolerance fit within the shaft keyway to prevent lash and mechanical wear.
- Optimal 6.375" Length: Provides full engagement across wide blower wheel hubs, distributing torque evenly for long-term stability.
- Direct OEM Compatibility: Specifically designed for York, Luxaire, and Coleman blower assemblies, eliminating the need for field modifications.
- Structural Integrity: High-density metal construction maintains its shape under high RPMs and thermal cycling.
Common Questions
What causes a blower key to fail?
Technicians typically see failures due to improper set screw tension or motor vibration, which leads to "wallowing" out the keyway. Replacing the York S1-001-07110-004 early prevents damage to the more expensive blower motor shaft.
Can I use standard 1/4" key stock instead?
While generic stock exists, this 6.375-inch square blower key is cut to a specific length required for specific York blower wheels. Using the exact OEM part ensures the key spans the entire hub, which is vital for preventing shaft scoring.
How do I ensure a secure installation?
Clear any burrs from the shaft keyway first. Fully seat the S1-001-07110-004 and then tighten the blower wheel set screw directly onto the center of the key to lock the assembly in place.
