The Multiquip 20134-001 Gearbox Assembly with Fan is a genuine OEM component designed for JWN series mechanical ride-on trowels, including the JWN24HTCSL and JWN24HSCSL models. As a factory-sourced assembly, this unit delivers the correct gear ratios, tolerances, and integrated fan configuration specified for these non-overlapping blade trowel machines. Sourced directly through Multiquip's authorized parts program, the part ensures you are installing the exact component engineered for your machine — not an approximation. DHS Equipment stocks this genuine OEM part to keep your trowel running at full output without the guesswork of fitment uncertainty.
Key Features
- Genuine OEM Gear Tolerancing — Manufactured to Multiquip's original design specifications, ensuring the gear mesh, bearing seats, and fan mounting deliver the same performance as the original assembly.
- Integrated Fan Included — The fan ships as part of the complete assembly, so installation is straightforward with no separate sourcing of fan components required.
- Confirmed Fitment for JWN Series — Verified for JWN24HTCSL and JWN24HSCSL mechanical ride-on trowels, as well as the broader JWN platform of non-overlapping blade machines.
- Maintains Blade Speed and Power Transfer — A functioning gearbox transmits engine power cleanly to the trowel blades; a worn or failed unit causes uneven blade rotation, vibration, and loss of finishing control.
- Complete Assembly for Faster Turnaround — Replacing the full gearbox assembly rather than individual internal components restores drivetrain integrity in a single service step.
The gearbox assembly is the core power transfer component in a mechanical ride-on trowel, taking rotational input from the engine and converting it into the controlled blade movement that finishes concrete surfaces. The integrated fan assists with cooling of the gearbox housing during sustained operation, helping maintain lubricant viscosity and extending the service life of internal components. When the gearbox wears or fails, operators typically experience erratic blade speed, unusual noise from the drivetrain, or a complete loss of blade drive — all of which halt finishing work until the unit is replaced.
