York S1-001-07110-003 Shaft Key

The York S1-001-07110-003 Shaft Key is a critical OEM replacement component engineered for precision alignment in HVAC blower assembly and motor drive systems. Designed specifically for Coleman and Evcon equipment, this high-strength steel key ensures rigid torque transmission between the drive shaft and the blower wheel or pulley. For technicians managing industrial or residential air handlers, maintaining a secure fit in the keyway is essential to prevent vibration, shaft scoring, and mechanical slippage during high-torque startup cycles. This HVAC replacement part is manufactured to strict tolerances (0.85" x 6.5" x 0.75" nominal dimensions) to provide exact engagement, reducing the risk of premature wear on the drive train. When performing blower motor maintenance or replacing worn shafts, using this genuine York shaft key ensures your equipment remains balanced and operational under heavy static pressure loads.

Key Benefits

• Precision Fit: Machined for exact tolerances to prevent rotational play in the keyway and minimize vibration.
• High-Strength Construction: Forged from durable steel capable of withstanding industrial-grade torque and shear forces.
• Corrosion Resistance: Features a protective finish to resist moisture and atmospheric oxidation in air handling units.
• System Compatibility: Ensures seamless integration with York, Coleman, and Evcon blower assemblies.

Common Questions

Which HVAC systems use the S1-001-07110-003 key?
This shaft key is standard for many Coleman and Evcon residential heating and residential air conditioning units, specifically within the blower and drive assemblies.

Can I use an aftermarket universal key instead?
While universal keys exist, this OEM part provides the specific hardness and dimensional accuracy required to prevent damage to the shaft and blower hub, which can lead to expensive repairs.

What causes a shaft key to fail?
Keys typically fail due to loose setscrews on the pulley or blower wheel, leading to "fretting" or impact loading that shears the key or wallows out the shaft keyway.
