The Multiquip HU51774 Pivot Pin is a genuine OEM component designed for HTH-SERIES, HTH44T, and STH hydrostatic ride-on trowels. Sourced directly from Multiquip, this pivot pin matches the original part in material, dimension, and fit — so you can install with confidence and get your machine back to work without second-guessing compatibility. It is a direct OEM replacement for worn or damaged pivot pins on supported trowel models, with no adaptation required to seat correctly in the assembly.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional standards, ensuring the pin delivers the same load-bearing and wear characteristics as the part it replaces.
- Direct Drop-In Replacement — Engineered to match the original pivot point geometry on HTH-SERIES, HTH44T, and STH trowels, seating correctly in the pivot assembly without rework or modification.
- Broad HTH and STH Series Coverage — A single part number covers HTH-SERIES, HTH44T, and STH hydrostatic ride-on trowels, making it straightforward to source for your fleet.
- Maintains Blade Pitch Articulation — A correctly functioning pivot pin allows the trowel's blade pitch mechanism to articulate smoothly and consistently, preserving surface finish quality on the slab.
- Verified Multiquip OEM Part Number — Part number HU51774 is the exact Multiquip OEM reference, eliminating guesswork when cross-referencing against your service manual or parts diagram.
The pivot pin is a critical linkage component in the blade pitch control assembly of hydrostatic ride-on trowels. It forms the articulation point that allows the trowel blades to change pitch angle in response to operator input — a function essential for controlling finishing pressure and surface profile. When a pivot pin wears, corrodes, or fails, blade pitch becomes inconsistent or unresponsive, which can produce uneven concrete surfaces and put additional stress on surrounding linkage hardware.
