The Multiquip 803281 Drive Hub Indexed is a genuine OEM component designed for WBH-16 and WBH-21 series Whiteman hydraulic power buggies. As a direct OEM replacement, part 803281 is built to the same specifications as the original, ensuring correct engagement with the drivetrain without any guesswork. This part is confirmed to fit models including WBH21EPA, WBH-21EFP, WBH-21EF, WBH-16EAWD, WBH-16EAWDF, WBH-16, WBH-16E, WBH-16EF, and WBH-16F. Ordering the correct indexed drive hub by part number keeps your buggy in full working order and avoids the costly delays that come with an incorrect fit.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip tolerances, ensuring the indexing profile mates correctly with mating drivetrain components on WBH-series buggies.
- Indexed Design for Positive Engagement — The indexed hub profile locks into the correct rotational position during installation, eliminating alignment errors that can lead to uneven drive or premature wear.
- Broad WBH-Series Compatibility — Fits nine WBH-16 and WBH-21 series Whiteman hydraulic power buggies, including foam-filled tire, AWD, and EPA variants.
- Drivetrain Integrity — A worn or damaged drive hub causes loss of traction, erratic wheel engagement, and accelerated wear on connected axle and motor components; replacing it promptly restores smooth, consistent power delivery to the wheels.
- Direct OEM Sourcing via DHS Equipment — Supplied as a verified Multiquip genuine part, so the part number you order matches exactly what comes off the production line.
The drive hub is the interface between the wheel motor output and the wheel assembly on a Whiteman hydraulic power buggy. It transfers rotational force from the drive motor to the wheel, and the indexed design ensures it seats in a fixed, repeatable position so torque is applied evenly. When a drive hub wears, cracks, or loses its indexing profile, the result is wheel slip, vibration, or complete loss of drive on that corner — conditions that can make a loaded power buggy difficult or unsafe to control on a pour site.
