Key Features
- Exact OEM Dimensioning — Manufactured to precise 3 x 3.7 mm tolerances, matching the original key geometry for a secure shaft-to-hub lock.
- Genuine Multiquip OEM Part — Sourced from Multiquip's authorized supply chain, this part meets the same material hardness and shear-resistance specifications as the original.
- Broad Equipment Compatibility — Fits MVH502DSB, MVH502DSB2, MQ41TDH, and MDR-9D models, covering reversible plate compactors, trash pumps, and ride-on trowels within the Multiquip lineup.
- Positive Drive Retention — A correctly fitted Woodruff key locks rotating components in precise angular alignment, preventing slippage under load and maintaining full power transfer through the drivetrain.
- Drop-In Replacement — Matches the original keyway profile for straightforward installation into the existing slot without recutting or shimming.
A Woodruff key is a small, semi-circular metal key that seats into a matching keyway cut into a shaft and its mating hub or sprocket. Its purpose is to lock the two components together rotationally, so torque is transferred evenly without slippage. When a Woodruff key shears, wears, or goes missing, the shaft and hub lose their positive drive connection — causing the attached component to spin freely, operate out of timing, or fail to transmit power altogether. Replacing a damaged key promptly with a correctly sized OEM part restores full mechanical engagement and prevents accelerated wear to the surrounding keyway surfaces.
