The Multiquip 20938 Thrust Assembly Service is a genuine OEM component designed for Whiteman and international ride-on power trowel models including HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, HHN34TVD, HHNG5, HHXD5, HHXD5-ES, HHXDF4-DF5, HHXG5, HTN27K, HTN28K, and EHHNK5. As a direct OEM replacement, part 20938 is produced to the same specifications as the original, ensuring a correct fit within the trowel's rotor thrust system. Sourced through DHS Equipment, this part is backed by Multiquip's OEM supply chain, giving you confidence that you're installing the right component the first time.
Key Features
- Genuine OEM Thrust Tolerancing — Manufactured to Multiquip's original design specifications, maintaining the load-bearing precision required in a high-cycle rotor thrust application.
- Direct Assembly Replacement — The 20938 replaces the complete thrust assembly as a service unit, simplifying installation without the need to source individual sub-components separately.
- Broad Ride-On Trowel Compatibility — Fits HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, HHN34TVD, HHNG5, HHXD5, HHXD5-ES, HHXDF4-DF5, HHXG5, HTN27K, HTN28K, and EHHNK5 ride-on power trowels.
- Consistent Blade Pitch Control — A properly functioning thrust assembly maintains accurate blade pitch adjustment across the rotor; a worn or failed unit can cause uneven finishing and loss of pitch response.
- Operational Safety Compliance — Correct thrust assembly function is critical to controlled blade operation on ride-on trowels; using a verified OEM service assembly helps maintain safe, predictable machine behavior.
The thrust assembly in a ride-on power trowel transfers the mechanical load from the pitch-adjustment mechanism down through the rotor, allowing the operator to change blade angle during finishing passes. It sits at a critical junction between the rotor hub and the blade arm pivot system, absorbing both axial and rotational forces generated during operation. When the thrust assembly wears or fails, operators typically notice inconsistent blade pitch response, unusual rotor vibration, or difficulty maintaining a flat, even finish — all signs that the assembly needs immediate service.
