The Multiquip 3311 is a genuine OEM Key 7 mm x 8 mm x 1-1/4 designed for Whiteman hydraulic power buggy models in the WBH-16 and WBH-21 series. As a direct OEM replacement, this key is manufactured to the exact dimensions required for proper shaft-to-hub engagement across compatible WBH configurations. Confirmed fitment includes WBH-16, WBH-16E, WBH-16EF, WBH-16F, WBH-16EAWD, WBH-16EAWDF, WBH-21EF, and WBH-21EFP power buggies. Sourcing the correct OEM key ensures the drivetrain connection is restored to its original specification without any dimensional guesswork.
Key Features
- OEM-Matched Dimensions — Produced to the exact 7 mm x 8 mm x 1-1/4 profile specified by Multiquip, ensuring the key seats fully and transfers torque correctly without slippage or play.
- Direct Shaft Fit — Engineered to drop into the keyway on WBH-series drivetrain shafts with no filing, grinding, or shimming required.
- Broad WBH-Series Compatibility — Fits WBH-16, WBH-16E, WBH-16EF, WBH-16F, WBH-16EAWD, WBH-16EAWDF, WBH-21EF, and WBH-21EFP Whiteman hydraulic power buggies.
- Torque Transfer Integrity — A correctly sized key locks the hub and shaft together so full drive power reaches the wheels; an undersized or worn key allows rotational slippage that accelerates wear on both mating components.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, carrying part number 3311 for straightforward verification against your parts manual or service documentation.
A woodruff or parallel key is a small but load-bearing component that locks a rotating shaft to a mating hub, pulley, or sprocket so that torque is transferred evenly between them rather than relying solely on a friction fit or fastener. On a hydraulic power buggy like the WBH series, the drive system depends on this key remaining fully seated and undamaged to maintain consistent, controlled movement under load. When a key shears, deforms, or works loose, the shaft spins independently of the hub, causing loss of drive, increased vibration, and accelerated wear to the keyway itself — making prompt replacement with a correctly dimensioned part essential to restoring full machine function.
