The Multiquip 511717 Woodruff Key 1/8" x 5/8" is a genuine OEM component designed for WBH-16 and WBH-21 series Whiteman hydraulic power buggies. As a direct OEM replacement, this key is manufactured to the exact dimensions and material specifications required by Multiquip, ensuring a correct fit in the keyway without rework or modification. It is compatible across the full WBH-16 and WBH-21 model range, including the WBH-16, WBH-16E, WBH-16EAWD, WBH-16EAWDF, WBH-16EF, WBH-16F, WBH-21EF, WBH-21EFP, and WBH21EPA. Sourced directly through authorized channels, part number 511717 is the correct OEM replacement to keep your buggy's drivetrain running as designed.
Key Features
- Exact OEM Dimensions — Manufactured to the precise 1/8" x 5/8" Woodruff profile specified by Multiquip, ensuring full keyway engagement without play or slop.
- Drop-In Drivetrain Fit — Seats directly into the existing keyway on WBH-16 and WBH-21 series buggies with no machining or custom fitting required.
- Broad WBH Series Compatibility — Fits WBH-16, WBH-16E, WBH-16EAWD, WBH-16EAWDF, WBH-16EF, WBH-16F, WBH-21EF, WBH-21EFP, and WBH21EPA models.
- Torque Transfer Integrity — A correctly fitted Woodruff key locks the shaft and hub in alignment, maintaining full torque transfer to the drive system. A worn or missing key causes slippage, vibration, and accelerated component wear.
- Genuine OEM Part — Sourced through Multiquip's authorized supply chain, so you get the same part installed at the factory — not an approximation.
A Woodruff key is a small, semicircular metal key that fits into a matching slot machined into a shaft and its mating hub or pulley, locking them together so they rotate as a single unit. On a power buggy like the WBH series, this key is critical to maintaining positive drive between the engine or motor shaft and the drive components — without it, the hub can spin freely on the shaft, causing immediate loss of drive and potential damage to the surrounding keyway. When a Woodruff key shears, cracks, or works loose, the result is typically slippage, unusual vibration, or complete loss of power transmission, making prompt replacement essential to restoring full operation.
