The Multiquip 21392 is a genuine OEM Pump Control Lever Pivot Mount designed for HTX44 and STX55 series hydrostatic ride-on power trowels. As a direct Multiquip OEM part, 21392 is manufactured to the same standards as the original component, ensuring a correct installation with no guesswork on fit or function. This mount is confirmed compatible with the HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, and STX55Y6 models, making it a straightforward replacement for operators running Kubota- or Yanmar-powered machines in either series.
Key Features
- Genuine OEM Construction — Manufactured by Multiquip to original design tolerances, ensuring the pivot point geometry matches the hydraulic pump control linkage exactly as engineered.
- Direct-Mount Replacement — Bolts into the existing mount location on HTX44 and STX55 frames without reworking surrounding hardware or linkage components.
- Broad STX/HTX Series Coverage — Fits HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, and STX55Y6 ride-on trowel models, covering both Kubota and Yanmar engine variants.
- Smooth Pump Control Response — A sound pivot mount allows the operator to move the pump control lever with consistent resistance and accurate response; a worn or cracked mount introduces slop in the linkage and degrades hydraulic drive control.
- Critical Hydraulic Drive Component — On hydrostatic trowels, precise pump control is essential for safe blade speed and machine travel; maintaining this mount in good condition keeps operator inputs translating accurately to the hydraulic system.
The pump control lever pivot mount is the structural anchor point for the lever that adjusts hydraulic pump output on hydrostatic ride-on trowels. When the operator moves the control lever, this mount carries the mechanical load of that input and transfers it accurately to the pump linkage — directly influencing blade RPM and machine drive response. When this mount cracks, wallows out, or loses rigidity, the lever develops unwanted play, causing imprecise hydraulic pump displacement and inconsistent trowel performance across the finishing pass.
