The Multiquip 21510 Tank W/A Hydraulic Burp is a genuine OEM component designed for HTX44 and STX55 series hydrostatic ride-on power trowels. This part is sourced directly from Multiquip, ensuring it meets the exact specifications required by the hydraulic system on these machines. Confirmed fitment includes the HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, and STX55Y6 models. When your hydraulic system needs servicing, installing the correct OEM part like the 21510 keeps the system operating as designed.
Key Features
- Genuine OEM Hydraulic Compatibility — Manufactured to Multiquip's exact hydraulic system specifications, ensuring proper pressure relief and fluid capacity for the burp function on these trowels.
- Direct-Fit Installation — Mounts to the existing hydraulic circuit on HTX44 and STX55 machines using the original hardware points, with no adaptation required.
- Broad HTX44 and STX55 Coverage — Verified fitment across HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, and STX55Y6 hydrostatic ride-on trowel models.
- Hydraulic System Integrity — A functioning burp tank allows trapped air to purge from the hydraulic circuit, which is essential for consistent blade pitch control and smooth machine drive response.
- Genuine Part Confidence — As a Multiquip OEM part, the 21510 carries the manufacturer's traceability and quality assurance backing — critical for a hydraulic component subject to continuous pressure cycling.
The hydraulic burp tank serves as a small reservoir within the ride-on trowel's hydraulic circuit, allowing air to be expelled — or "burped" — from the system during bleeding and servicing procedures. On hydrostatic trowels like the HTX44 and STX55, the hydraulic system controls both blade pitch adjustment and machine propulsion, so any air contamination in the circuit can cause erratic blade response or sluggish drive performance. A damaged or missing burp tank prevents proper system bleeding, making this component an important part of routine hydraulic maintenance on these machines.
