Multiquip EM11431 Thrust Collar with Bushing

The Multiquip EM11431 Thrust Collar with Bushing is a genuine OEM component designed for HHN, HTX, and HTN series ride-on power trowels. This part is sourced directly from Multiquip and meets the same specifications as the original component installed at the factory, giving you confidence in fitment and long-term durability. Confirmed compatible models include EHHNK5, HHN31VTCSL5, HHN34TVD, HHNG4, HHNG5, HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, HTN27KTCSL, HTN28KTCSL, HTN31VTCSL5, HTH44T, and additional HHX and HTNS variants. If you are servicing a mechanical, hydrostatic, or international-spec ride-on trowel in the HHN or HTX family, verify your model against part number EM11431 before ordering.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original dimensional and material tolerances, ensuring the collar and bushing interface holds up under the rotational loads specific to ride-on trowel blade assemblies.
• Direct Drop-In Replacement — Engineered to install in the same position and orientation as the original, with the bushing pre-integrated into the collar for straightforward service.
• Broad Ride-On Trowel Compatibility — Fits across the HHN, HTX, and HTN model families, including mechanical and hydrostatic variants such as HTX44K4, HTX44Y5, HHN34TVD, and HTN28KTCSL.
• Axial Load Control — The thrust collar manages axial forces on the rotating shaft, preventing unwanted lateral movement that can cause blade pitch inconsistency and accelerated wear on surrounding components.
• Bushing Integration Protects Mating Surfaces — The included bushing reduces metal-to-metal contact at the collar interface, limiting wear on the shaft and housing during continuous troweling operation.

The thrust collar with bushing is a precision hardware component positioned along the trowel's rotating gearbox or blade-pitch shaft to manage axial (end-to-end) load. Its job is to keep the shaft in a fixed lateral position while allowing it to rotate freely — without it, the shaft can walk or shift under load, throwing off blade pitch and placing undue stress on gears, seals, and adjacent bearings. The integrated bushing acts as a low-friction wear interface between the collar and its mating surface. When this part wears or fails, operators typically notice irregular blade behavior, increased vibration, or unusual noise from the gearbox — all signs that the collar is no longer controlling shaft movement correctly.
