The Multiquip 12906 Gear Box Input Shaft With Fan is a genuine OEM component designed for HTN27K and HTN28K mechanical ride-on power trowels. As a direct OEM replacement, this shaft meets the original engineering specifications set by Multiquip for the HTN series, ensuring proper alignment and engagement within the gearbox assembly. Sourced directly through authorized channels, part 12906 is the correct replacement when the input shaft shows wear, damage, or play that affects trowel blade performance.
Key Features
- Genuine OEM Construction — Manufactured to the original material and dimensional specs for the HTN-series gearbox input shaft, ensuring the shaft and integrated fan meet the same tolerances as the part it replaces.
- Integrated Fan Design — The built-in fan is part of the shaft assembly itself, meaning both components are replaced together for consistent airflow and cooling performance at the gearbox.
- Direct HTN Series Fitment — Confirmed fit for HTN27K and HTN28K mechanical ride-on trowels; cross-reference part number 12906 against your machine's serial plate before ordering.
- Critical Drive Component — The input shaft transfers power from the engine into the gearbox to drive the trowel blades; a worn or damaged shaft causes erratic blade rotation, vibration, and loss of finishing control.
- Drop-In Replacement — Engineered to install into the existing HTN gearbox housing using the original mounting configuration, with no modification to the drivetrain required.
The gearbox input shaft is the primary mechanical link between the engine output and the trowel's blade drive system. It transmits rotational force into the gearbox, where it is distributed to the finishing blades; the integrated fan assists with cooling the gearbox housing during sustained operation. When this shaft wears, develops surface damage, or loses concentricity, operators will notice increased vibration, inconsistent blade speed, and accelerated wear on surrounding gearbox components — making timely replacement essential to maintaining a flat, consistent finish.
