Multiquip 21504 Bellhousing Kubota HTX44T Service Only

The Multiquip 21504 is a genuine OEM Bellhousing Kubota HTX44T Service Only designed for HTX44K4 and HTX44K5 hydrostatic ride-on power trowels. As a direct OEM replacement, part 21504 is produced to the exact specifications of the original component, ensuring proper alignment between the Kubota engine and the trowel's drivetrain. This part is designated for service use and is the correct replacement when the bellhousing on your HTX44 series machine requires renewal. Sourced directly through authorized Multiquip distribution, DHS Equipment supplies this part to keep your finishing equipment operating at full capacity.

Key Features

• Genuine OEM Construction: — Manufactured to original Multiquip specifications, ensuring correct bore dimensions and mounting geometry for the Kubota engine interface on HTX44 series trowels.
• Service-Only Designation: — Supplied as a standalone bellhousing for field service and overhaul, allowing technicians to replace the housing without sourcing a complete assembly.
• HTX44 Series Compatibility: — Confirmed fitment for HTX44K4 and HTX44K5 hydrostatic ride-on power trowels, covering both K4 and K5 Kubota diesel engine configurations.
• Drivetrain Alignment Integrity: — A correctly fitted bellhousing maintains precise concentricity between the engine output and transmission input; a cracked or worn housing can cause misalignment, vibration, and accelerated drivetrain wear.
• Authorized DHS Equipment Source: — Sold by DHS Equipment as an authorized Multiquip parts distributor, providing confidence in part authenticity and accurate part number verification.

The bellhousing is the structural bridge between the engine and the transmission or hydraulic pump assembly on a ride-on power trowel. It locates and encloses the flywheel and coupling components, keeping the engine and drivetrain in precise rotational alignment under the heavy loads generated during concrete finishing. When a bellhousing cracks, distorts, or sustains damage, misalignment between rotating components accelerates wear on bearings, seals, and couplings — and left unaddressed, can lead to more significant drivetrain failure. Replacing it with the correct OEM part, such as Multiquip 21504, restores the structural integrity of the engine-to-drivetrain connection and protects the surrounding components.
