The Multiquip 11712 Engine Speed Plate is a genuine OEM component designed for HTX44 and STX55 series hydrostatic ride-on power trowels. As a direct Multiquip OEM part, it is manufactured to the exact specifications required for correct throttle and engine speed control on these machines. Confirmed fitment includes the HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, and STX55Y6 models. When sourcing critical engine control components, using the correct OEM part like the 11712 ensures the machine's speed regulation system functions exactly as engineered.
Key Features
- Genuine OEM Specification: — Manufactured by Multiquip to the original design tolerances required for precise engine speed regulation on hydrostatic trowel platforms.
- Direct Drop-In Replacement: — Mounts in the original position using existing hardware, maintaining the correct geometry for throttle linkage alignment.
- Broad HTX44 and STX55 Coverage: — Fits HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, and STX55Y6, covering Kubota and Yanmar engine variants across both series.
- Consistent Engine Speed Control: — A correctly installed engine speed plate keeps throttle response stable across blade speed adjustments, supporting smooth, even finishing passes.
- Operational Safety Relevance: — Proper engine speed management on ride-on trowels is essential for operator control; a worn or damaged plate can introduce erratic throttle behavior during finishing operations.
The engine speed plate is a structural throttle control component that anchors and guides the linkage governing engine RPM on hydrostatic ride-on trowels. It provides the fixed reference point that allows the operator to set and hold consistent engine speed during finishing work. When this plate is worn, bent, or broken, throttle response becomes unpredictable — leading to uneven blade speeds, inconsistent surface finishing, and reduced operator control over the machine.
