The Multiquip 20353 Gearbox Machined JWN 1-1/8 Shaft is a genuine OEM component designed for JWN24HTCSL series mechanical ride-on power trowels. As a direct factory replacement, this machined gearbox is manufactured to the same specifications as the original unit, ensuring a correct drop-in fit without the need for modification. Confirm your model code against JWN24HTCSL before ordering to ensure proper fitment for your machine. DHS Equipment sources this part directly from Multiquip, so you can order with confidence knowing you are receiving an authentic OEM assembly.
Key Features
- Genuine OEM Machined Construction — Manufactured to Multiquip's original tolerances, delivering the precise bore sizing and shaft engagement critical for a gearbox assembly on a ride-on trowel.
- 1-1/8 Inch Shaft Specification — Built around the correct 1-1/8 inch shaft diameter, ensuring secure coupling and load transfer without shaft slippage or excessive play.
- Direct Replacement for JWN Series Trowels — Engineered specifically for JWN24HTCSL mechanical ride-on power trowels, matching the original mounting configuration and output interface.
- Sustained Blade Drive Performance — A properly functioning gearbox transfers engine torque evenly to the trowel blades; a worn or failed unit causes inconsistent blade speed, vibration, and surface finish defects in finished concrete.
- Sourced Direct from Multiquip — Sold as a genuine OEM assembly through DHS Equipment, an authorized Multiquip parts distributor, ensuring part authenticity and correct fit.
The gearbox on a ride-on power trowel is the core mechanical assembly responsible for transferring and reducing engine power to drive the rotating blade pans at the correct speed and torque. On JWN series mechanical trowels, which use non-overlapping blade configurations, the gearbox must maintain consistent output under sustained load to produce a uniform finish across the concrete surface. When a gearbox develops wear, stripped teeth, or bearing failure, the result is uneven blade rotation, increased vibration through the operator platform, and ultimately a loss of finishing quality that can compromise the concrete slab surface.
