Multiquip EM927040 Woodruff Key 606 (3/16 x 3/4)

The Multiquip EM927040 Woodruff Key 606 (3/16 x 3/4) is a genuine OEM component designed for the AR13HA, AR13H, AR13HC, AR13D, and AR14H asphalt ride-on roller series. As a direct Multiquip OEM part, EM927040 is manufactured to the same specifications as the original hardware installed at the factory, ensuring a correct, trouble-free fit. This small but critical fastening component seats precisely into the keyway between shaft and hub, keeping driven assemblies locked in proper alignment during operation. Confirm your roller model against the fitment list before ordering to ensure compatibility.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip OEM specification, delivering the exact material hardness and dimensional tolerance required for a Woodruff key application in a high-vibration roller drivetrain.
• Direct Drop-In Installation — The 606 profile (3/16 x 3/4) matches the original keyway geometry on compatible AR-series roller shafts, seating without modification or rework.
• Broad AR-Series Compatibility — Fits AR13HA, AR13H, AR13HC, AR13D, and AR14H Multiquip asphalt ride-on rollers, covering both Honda and diesel engine variants across the AR13 and AR14 families.
• Drivetrain Integrity — A correctly installed Woodruff key prevents hub slippage and rotational misalignment, protecting gears, pulleys, and impellers from uneven wear and premature failure.
• Exact Part Number Match — Ordering by part number EM927040 ensures you receive the correct key profile for your machine — not a generic substitute that may differ in width, depth, or radius.

A Woodruff key is a small, semi-circular or rectangular locking key that fits into a machined slot — called a keyway — cut into both a rotating shaft and the hub of a gear, pulley, or sprocket mounted on it. Its purpose is to prevent the hub from rotating independently of the shaft, transferring torque cleanly between the two components. When a Woodruff key shears, wears, or goes missing, the driven component can slip or spin freely on the shaft, causing loss of drive, erratic machine behavior, and accelerated damage to surrounding components. Replacing a worn or broken key promptly with the correct OEM part restores full power transmission and protects the integrity of the surrounding drivetrain.
