The Multiquip 32957-SK Gearbox Assembly LS Superior is a genuine OEM component designed for Whiteman heavy-duty ride-on power trowel models HHN34TVD, HHXD5, HHNG5, and HHXDF4-DF5. As a direct OEM replacement, part 32957-SK is manufactured to the same specifications as the original, ensuring a correct, trouble-free installation.

DHS Equipment stocks this part to help you get your ride-on trowel back to full operation without guesswork.

Key Features

• Genuine OEM Gear Tolerancing — Manufactured to the same internal gear mesh and bearing specifications as the original assembly, maintaining proper torque transfer through the blade drive system.
• Direct-Mount Replacement — Mounts in the same position and uses the same bolt pattern as the original gearbox, allowing for a straightforward swap without custom fitting or machining.
• Confirmed Fitment for HHN and HHX Series Trowels — Verified for HHN34TVD, HHXD5, HHNG5, and HHXDF4-DF5 Whiteman ride-on power trowels.
• Restores Full Blade Drive Performance — A worn or damaged gearbox causes erratic blade speed, vibration, and uneven concrete finishing; replacing it with this assembly brings blade rotation back to spec.
• Authorized Multiquip Part — Supplied as a genuine OEM assembly under part number 32957-SK, backed by Multiquip's established parts program.

The gearbox assembly is the mechanical heart of the blade drive system on a ride-on power trowel. It transfers power from the engine or hydraulic drive to the finishing blades, controlling rotational speed and torque to achieve a consistent, smooth concrete surface. When the gearbox begins to fail — through worn gears, failed bearings, or seal breakdown — operators will notice increased noise, blade speed inconsistency, and a decline in finish quality. Replacing a worn gearbox assembly promptly with a correct OEM unit prevents secondary damage to the drive train and keeps the trowel performing to its rated capacity.
