Key Features

• Genuine OEM Specification: — Manufactured to the exact dimensional tolerances required for proper shaft-to-hub engagement across every compatible model in this application range.
• Broad Cross-Equipment Compatibility: — A single stocked part number covering rammers (MTX70HDR, MTX80HDR), plate compactors (MVC and MVH series), concrete and mortar mixers (MC, EC, WC, WM, CMS, EM series), masonry and concrete saws, walk-behind trowels, and pumps.
• Drop-In Shaft Fit: — The Woodruff key profile seats directly into the milled keyway on the crankshaft or drive shaft, aligning the driven component without any machining or adaptation.
• Torque Transmission Integrity: — A correctly seated Woodruff key locks the drive component to the shaft so power transfers cleanly; a worn or missing key causes slippage, vibration, and accelerated hub and shaft wear.
• Wide Engine and Platform Coverage: — Compatible across Honda-powered, electric, and gas-powered variants throughout the Multiquip, Whiteman, Essick, and STOW product lines, making it a practical part to keep on hand for multi-machine fleets.

A Woodruff key is a small, semicircular metal key that fits into a matching slot (keyway) cut into both a shaft and the hub of a component mounted on that shaft — such as a flywheel, pulley, impeller, or drum drive gear. Its purpose is to prevent the mounted component from rotating independently of the shaft, ensuring that rotational force is transmitted consistently and without slippage. When a Woodruff key shears, deforms, or works loose, the driven component spins freely on the shaft, causing loss of drive, vibration, abnormal noise, and potential damage to the shaft keyway itself — making prompt replacement essential to restoring full machine function.
