The Multiquip 12772 is a genuine OEM Right Hand Worm Gear Ht 1-1/4 designed for HTN and HTNS series Whiteman ride-on power trowels, including the HTN27K, HTN28K, and HTNS5S-2. As a direct Multiquip OEM component, 12772 is manufactured to the same specification as the original part, ensuring correct mesh geometry and load transfer within the trowel's gearbox. This gear is a critical drivetrain component — if the worm gear is worn or damaged, blade pitch control and overall trowel performance will be compromised. Confirm your model number before ordering to ensure this is the correct-hand gear for your application.
Key Features
- OEM-Matched Gear Profile: — Cut and hardened to the original worm gear specification, ensuring correct tooth engagement and smooth torque transfer in the trowel gearbox.
- Right-Hand Orientation: — Designated right-hand (RH) configuration matches the directional geometry of the original drivetrain — verify hand orientation against your machine before ordering.
- Confirmed Fitment: — Compatible with HTN27K, HTN28K, HTNS5S-2, and related HTN-series Whiteman ride-on power trowels.
- Blade Pitch Performance: — A correctly functioning worm gear maintains precise blade pitch adjustment, enabling smooth, consistent concrete finishing across the full trowel pass.
- Genuine Multiquip OEM Part: — Sourced directly through the Multiquip OEM supply chain under part number 12772, giving you traceability and confidence in part authenticity.
The worm gear is a core element of a ride-on trowel's pitch adjustment mechanism. It works in conjunction with a worm wheel to convert rotational input into the angular movement that controls blade pitch — the angle at which the finishing blades contact the concrete surface. When the worm gear wears or fails, the operator loses the ability to make accurate pitch adjustments, leading to uneven finishing pressure, surface defects, and potential damage to the gearbox assembly. Replacing a worn worm gear promptly restores full pitch control and protects the surrounding drivetrain components from accelerated wear.
