Multiquip 12056 Cylinder 2.5" Bore x 1.5" Str x 0.75" Rod

The Multiquip 12056 is a genuine OEM Cylinder 2.5" Bore x 1.5" Str x 0.75" Rod designed for Whiteman ride-on power trowels across the PRX, STX, and HTX series. As a direct OEM replacement, part 12056 is manufactured to the same specifications as the original component, ensuring it seats and operates exactly as the factory-installed unit. This cylinder is confirmed to fit a wide range of models including PRX, STX55Y6, STX55J6, STX6H, STXD6i, STXDF, HTX6H, HTXD6i, HTXG6DF, HTX44Y4, HTX44Y5, HTX44K4, HTX44K5, HHXG5, HHXD5, HHXD5-ES, and HHXDF4-DF5. Sourcing the correct hydraulic cylinder by 12056 is critical on ride-on trowels — an improperly spec'd cylinder affects blade pitch response and overall machine control.

Key Features

• Genuine OEM Bore and Stroke Tolerances — Manufactured to the exact 2.5" bore, 1.5" stroke, and 0.75" rod dimensions of the original, ensuring full hydraulic pressure retention and consistent blade pitch actuation.
• Direct Bolt-In Replacement — Matches the original mounting points and hydraulic port configuration, allowing straightforward installation without machining or adapter fittings.
• Broad Ride-On Trowel Compatibility — Fits PRX hybrid, STX super-sized hydrostatic, HTX heavy-duty hydrostatic, and HHX series Whiteman ride-on power trowels, covering multiple engine and fuel configurations.
• Consistent Blade Pitch Control — A properly functioning cylinder maintains precise, responsive control over blade pitch angle, directly affecting finish quality and operator feel on the slab.
• Hydraulic System Integrity — Built to withstand the continuous hydraulic cycling demands of ride-on trowel operation, resisting internal leakage that would cause sluggish or uneven blade response.

The hydraulic cylinder on a ride-on power trowel controls the pitch angle of the finishing blades by extending and retracting in response to hydraulic pressure from the machine's control system. Precise blade pitch adjustment is what allows the operator to transition between floating and finishing passes, and a cylinder that leaks internally or loses stroke accuracy will result in uneven blade angles, inconsistent concrete surface finish, and reduced operator control. Replacing a worn or damaged cylinder with a correctly spec'd OEM unit restores full hydraulic authority over blade positioning and keeps the trowel performing as intended across the full range of finishing work.
