Murray 2105337sm Hi-pro Key 0.250 X 2.0 Inches

Product Description

The MURRAY 2105337sm is a Hi-Pro key designed as a precision drive-train component for lawn and garden equipment. Keys of this type seat into a shaft keyway to lock rotating components such as blades, pulleys, or sprockets in proper angular alignment, preventing slippage under load. Measuring 0.250 inches by 2.0 inches, this key is sized to fit specific Murray-manufactured shaft and hub assemblies. It is a direct OEM replacement part intended for installation by equipment technicians and experienced service professionals.

This key is used in Murray-branded lawn and garden power equipment, including walk-behind mowers, riding mowers, and related drive systems that use Hi-Pro keyway configurations. Replacement is typically required when the original key shears due to blade strike impact or normal wear. The small footprint and standardized profile make it a straightforward service part for routine drivetrain maintenance.
