The Multiquip 21510-001 is a genuine OEM Hydraulic Burp Tank W/A designed for HTX44 and STX55 series Whiteman ride-on power trowels. This OEM component is sourced directly from Multiquip, ensuring it meets the exact specifications required for proper hydraulic system function on your machine. Confirmed fitment includes HTX44K4, HTX44Y4, HTX44K5, HTX44Y5, STX55J6, and STX55Y6 models. Choosing the correct OEM part means no guesswork on compatibility and a straightforward installation that restores your machine to proper working condition.
Key Features
- Genuine OEM Construction — Built to Multiquip's exact material and dimensional specifications, ensuring the hydraulic burp tank seats, seals, and vents correctly within the trowel's hydraulic circuit.
- Direct-Fit Replacement — Designed as a drop-in replacement for the original unit, matching all mounting points and hydraulic line connections on HTX44 and STX55 series trowels.
- Broad HTX44 and STX55 Compatibility — Fits HTX44K4, HTX44Y4, HTX44K5, HTX44Y5, STX55J6, and STX55Y6, covering both Kubota and Yanmar engine variants across the heavy-duty hydrostatic trowel lineup.
- Protects Hydraulic System Integrity — A functioning burp tank allows trapped air to purge from the hydraulic system; a failed or missing tank can cause erratic blade response, pressure loss, and accelerated wear on hydraulic components.
- Verified Part Number — Order with confidence using Multiquip part number 21510-001, cross-referenced directly to the HTX44 and STX55 parts documentation.
The hydraulic burp tank serves as an air-purging reservoir within the trowel's closed hydraulic system. As hydraulic fluid circulates under pressure, small amounts of air can become entrained in the system; the burp tank provides a controlled space for that air to escape, keeping the hydraulic fluid delivery consistent and the blade pitch response predictable. When this tank is cracked, missing, or improperly sealed, air remains trapped in the hydraulic lines, leading to spongy or inconsistent blade control and potential damage to hydraulic pumps and motors over time.
