The Multiquip 11248 Gearbox Adaptor Plate Assembly is a genuine OEM component designed for HTN-series ride-on power trowels, including the HTN27K, HTN28K, and HTNS5S-2. As a direct OEM replacement, this assembly ensures the gearbox interfaces correctly with the trowel drivetrain without deviation from the original design specification. Sourced directly through Multiquip's authorized parts channel, the 11248 is the correct part for maintaining proper mechanical alignment in these machines. Confirm your model code against the fitment list before ordering to ensure compatibility.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the adaptor plate mates precisely with the gearbox housing and mounting surfaces on HTN-series trowels.
- Direct Bolt-On Replacement — Replaces the original 11248 assembly using the existing mounting points on the HTN27K, HTN28K, and HTNS5S-2, keeping installation straightforward.
- Broad HTN-Series Coverage — Fits Whiteman HTN27K, HTN28K, and international HTNS5S-2 ride-on power trowels, covering multiple engine configurations including Kohler, Onan, and Honda variants.
- Structural Integrity for Drivetrain Alignment — A worn or damaged adaptor plate causes gearbox misalignment, which accelerates wear on drive components and degrades blade pitch control — this assembly restores correct drivetrain geometry.
- Verified Part Number — The Multiquip part number 11248 is confirmed against the HTN-series parts catalog, giving you confidence you are ordering the right assembly for your machine.
The gearbox adaptor plate assembly serves as the structural interface between the trowel's gearbox and the main frame or drive assembly. It positions and secures the gearbox so that rotational force is transferred cleanly to the trowel blades, maintaining consistent blade speed and pitch response. When this plate becomes cracked, warped, or worn at its mounting surfaces, the gearbox can shift out of alignment, causing vibration, uneven blade engagement, and premature wear on surrounding drivetrain components.
