The Multiquip 11643 is a genuine OEM Rod End 1/4-28 Male RH designed for HTX44 and STX55 series hydrostatic ride-on power trowels. As a direct OEM replacement sourced through Multiquip's authorized parts supply, part 11643 meets the original engineering specifications for thread pitch and hand orientation — critical factors for correct linkage function on these machines. Confirmed fitment covers the HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, and STX55Y6 models. Verify your model code before ordering to ensure compatibility.
Key Features
- Genuine OEM Thread Specification — Manufactured to the exact 1/4-28 UNF right-hand thread spec, ensuring proper engagement with mating linkage hardware without reworking threads.
- Direct Bolt-In Replacement — Matches the original mounting interface on HTX44 and STX55 control linkages, allowing straightforward swap-out during scheduled maintenance or repair.
- Broad HTX and STX Series Fitment — Compatible across HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, and STX55Y6 Whiteman hydrostatic ride-on trowels.
- Linkage Integrity Under Load — A correctly functioning rod end maintains smooth, precise blade pitch control; a worn or loose rod end introduces slop into the control circuit, causing uneven finishing and unpredictable blade response.
- Operational Safety at the Blade Controls — Rod ends in the pitch control linkage are load-bearing steering components; using a correctly rated OEM part supports accurate operator control and reduces the risk of linkage failure during operation.
A rod end, sometimes called a heim joint, is a spherical bearing assembly threaded onto a control rod or linkage arm. On hydrostatic ride-on trowels like the HTX44 and STX55, rod ends are used in the blade pitch control linkage to transmit operator inputs to the rotor arms with minimal friction and consistent articulation. The 1/4-28 right-hand thread designation defines exactly how the rod end attaches to the adjoining hardware — incorrect thread pitch or hand orientation will prevent proper engagement. When a rod end wears out, develops play in the ball socket, or the threads strip, blade pitch response becomes inconsistent, which directly impacts the quality of the concrete finish and the operator's ability to control the machine predictably.
